Care should be taken to prevent objects or liquid from entering the enclosure. Never handle the power cord with wet hands. · The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of uninsulated "dangerous voltage" within the product's enclosure that may constitute a risk of electric shock to you. The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the unit. Caution: To prevent the risk of electric shock, do not remove cover. No user-serviceable parts inside. Refer servicing to qualified service personnel. If an outdoor antenna is connected to the antenna input, be sure it is grounded to provide some protection against voltage surges and built up static charges. Keep the outdoor antenna away from power lines. Unplug the receiver from the AC outlet when plugging in or unplugging cables, when left unused for an extended period of time, moving the receiver, or when you suspect lightning in your area. Prevent damage to the power cord. Do not bend, pull, place objects on, alter, etc. Replace the power cord if it becomes damaged. Always grasp the plug on the power cord when plugging in or unplugging the receiver from the AC outlet. Your system may produce sound levels capable of causing permanent hearing loss. Do not operate for extended periods of time at high volume levels. Make sure the receiver is placed on a level surface. Protect the receiver from impact. (Do not drop it!!!) Do not climb on top of the receiver or place heavy objects on its top cover. The receiver is equipped with raised feet to provide ventilation, reduce acoustic feedback, and provide protection against scratching the surface the unit is resting on. We advise against removing or altering feet. Do not stack anything on top of the receiver (processor, source, etc.) Leave a minimum of 3" clearance from the top of the receiver to the next shelf (or component). The receiver should be located away from sources sensitive to heat. Do not perform any internal modifications to the receiver. Always connect the receiver's power cord to an unswitched AC outlet for normal operation. If young children are present, adult supervision should be provided until the children are capable of following all rules for safe operation. Do not plug the receiver's power cord into an outlet with an unreasonable number of other devices. Be careful if using extension cords and ensure the total power used by all devices does not exceed the power rating (watts/amperes) of the extension cord. Excessive loads may cause the insulation on the cord to heat and possibly melt. Mistaking CONTROL OUTPUT or IR INPUT connectors for audio/video inputs or outputs may damage your receiver or other components. Damage can occur to your speakers if the power rating of each individual driver is exceeded by the receiver. Ensure that all the drivers in your system are capable of handling not only the average power being delivered by the amplifiers, but also the peak power that is likely to be generated during strong passages. If you are unsure of your speaker's power rating, contact the speaker manufacturer or the dealer where you purchased them. The receiver should be serviced by qualified personnel when: A. The receiver is not functioning properly. B. Objects have entered the chassis. C. The receiver was exposed to rain or other type of moisture. D. The receiver was dropped, or the chassis is damaged. · · · · · · · · · · · · · · · · · · 2 FEATURES Your new receiver is a versatile audio/video control center.

Sources - your receiver can provide audio from its built-in AM/FM tuner. It can also provide limited video from its on-screen menu system. You will want to connect a number of additional sources (VCR, DVD player, etc.) to your receiver. Your receiver is designed to accommodate a wide range of audio and video signals. The following table lists the most popular home theater media and how the audio information is stored. Source Media Audio Cassette Video Cassette Laser disc (LD) Compact Disc (CD) Digital Versatile Disc (DVD) Satellite Broadcast Digital Audio Tape (DAT) Digital Compact Cassette (DCC) Mini disc (MD) Analog X X X PCM Dolby Digital DTS X X X X X X X (compressed) X (compressed) X X X X X X X X X Analog vs. Digital Audio - This refers to the method used to place audio information on the source material and how they are delivered to your receiver from the source. Analog signals exactly represent the sound you will hear through a continuously varying voltage. Audio and videocassettes are analog recordings and are normally delivered to your receiver over a pair of coaxial audio cables. Digital signals closely approximate the original audio signals with a set of numbers referred to as a bitstream. CDs and DVDs are sources of digital audio and are normally connected to your receiver through a coaxial or optical digital cable. There are several different bitstream formats available. The simplest format is called Pulse Code Modulation (PCM). In PCM, the bitstream directly represents the original 2-channel audio. In Dolby Digital and DTS (see "Surround Formats" below) bitstreams are modified using a process called compression to squeeze more information into limited space. DTS squeezes 5.1 channels into the space normally required for two uncompressed channels, while Dolby Digital squeezes 5.1 channels into about ¼ the space required for two channels. Your receiver automatically detects the bitstream currently being provided from the source and performs the required decompression and surround processing. If no digital signal is present your receiver will automatically switch to analog processing. All sounds that you hear from your speakers are analog. Digital signals are automatically converted to analog by your receiver before being output to your the speakers. If analog signals exactly represent the audio, while digital signals only approximate it, why would I want to use digital? All analog sources add some amount of noise and distortion to the audio signal. Additional noise can be picked up through the cables from the source to your receiver. It is impossible for the receiver to tell the difference between the desired signal and the added noise and distortion, so it reproduces both of them. The result is increased background noise and decreased dynamic range and fidelity. Digital signals are virtually immune to noise and distortion. The receiver can, therefore, reproduce the signal with the greatest possible fidelity. We recommend you use digital signals wherever possible. Also Dolby Digital and DTS (see "Surround Formats" below) work only with digital signals. Audio and Surround Formats - Your source material will be in one of seven possible formats described below. Monaural (Mono) - This is the oldest format available. It contains a single, full range audio channel. Modern recordings are seldom made in this format, but older movies and music are available only in this format. You may get mono from any source - digital or analog. Sound will normally come from the seven speaker channels, but your receiver can produce mono in one to seven channels (see "Audio Modes under Operation"). Since all modern sources are stereo, the mono information is usually replicated from both the left and right channels. 4 Stereo - Stereo contains two discrete, front left and right full range audio channels. This is the most common format for music and is also used on many movies. You may get stereo from any source - digital or analog. Sound will normally come from the seven speaker channels, but your receiver can produce stereo in one (mono) to seven channels (see "Audio Modes under Operation"). Dolby Pro Logic - Dolby Pro Logic is a refinement of Dolby Surround, which was the earliest form of true surround processing. Like Stereo, Dolby Surround contains two discrete, full range audio channels. In addition, a monaural, limited range surround channel is encoded on the two stereo channels in a process called matrixing. The surround channel information is encoded in positive polarity on the left channel and in negative polarity on the right channel. The Dolby Processor can detect this encoding (left minus right) and send that information to the surround channels. Dolby Pro Logic adds additional processing to produce a full range center channel by extracting the mono information from the left and right channel. This is the most common format for all but the most recent movies. Music sources are occasionally encoded in Dolby Surround. However, many people prefer to use Pro Logic processing on all of their stereo sources. The center channel extraction process often yields improved stereo imaging, especially when you are sitting away from the "sweet spot" at center of the listening area. The surround channel processing often lends a pleasing ambiance even to material that is not encoded in Dolby Surround. Dolby Pro Logic is fully compatible with stereo and you may get it from any source - digital or analog. Sound will normally come from all seven speakers in your system, but your receiver can produce sound in one (mono) to seven channels (see "Audio Modes under Operation"). Dolby Pro Logic II - Pro Logic II brings exciting new features and advanced performance for decoding the many thousands of existing Dolby Surround programs, making them sound more like a discrete Dolby Digital 5.1channel version than ever before. Pro Logic II is able to decode the thousands of existing Dolby Surround movies and TV shows already on the shelf, compatibly, and with enhanced image stability. The improvements in decoding techniques mean that the discreteness of the sound field elements are better preserved in the decoding process than was possible with the now universally standard Pro Logic technology. Pro Logic II offers a music mode to expand stereo non-matrix recordings into a five-channel layout in a way that does not diminish the subtlety and integrity of the original stereo recordings. Dolby Digital - Dolby Digital contains up to five discrete, full range audio channels plus an additional Low Frequency Effects (LFE) channel. The LFE channel contains only low frequency information for enhanced sound effects in movies. This combination of five discrete channels plus a LFE channel is often referred to as 5.1 channels. Dolby Digital is a digital format only. It must be delivered to your receiver over a coaxial or optical digital cable. As of the writing of this manual, Dolby Digital is commercially available on DVD and Satellite (Also see Dolby Digital RF below). It is also possible to create your own Dolby Digital CDs and DATs if you have the recording equipment. You can't directly record Dolby Digital onto mini disc or digital compact cassette since these devices add their own compression, which is incompatible with the Dolby Digital compression. Not all Dolby Digital recordings will include all five channels, and, in fact, it is common on DVDs to have two channel Dolby Digital with or without Pro Logic processing. Sound will normally come from all seven speakers in your system, but your receiver can produce sound in one (mono) to seven channels (see "Audio Modes under Operation"). Dolby Digital RF - Dolby Digital RF is identical to normal Dolby Digital except that it uses a special RF encoding scheme to put the bitstream on Laser discs without replacing the normal stereo (or Dolby Surround) PCM bitstream that is normally available from laser disc. In order to use Dolby Digital RF laser discs you must have a B&K DT-1 RF demodulator or similar product from another manufacturer. For best results with your receivers Plug and Play capability we recommend the B&K DT-1. Dolby Digital Surround EX - Dolby Digital Surround EX is a new movie sound track that greatly enhances the sense of spatial and positioning of the surround channel sound. This system was developed jointly by Lucasfilm THX and Dolby Laboratories, using Lucas film's idea of improving spatial expression and achieving a 360-degree sound positioning with Dolby Laboratories' matrix encoding technology. The surround back channel is matrixencoded and inserted into both Dolby Digital SL (surround left) and Dolby Digital SR (surround right) channels. Upon playback, the signals may be decoded by a high precision digital matrix decoder within the Dolby Digital decoder into SL, SR and SB channels. DTS (Digital Theater Systems) - DTS is similar to Dolby Digital in that it provides 5.1 discrete audio channels. However, it uses more digital data to encode the information and may provide greater fidelity than Dolby Digital. DTS is a digital format only. It must be delivered to your receiver over a coaxial or optical digital cable. No RF demodulator is required for DTS laser discs since the DTS bitstream replaces the normal PCM bitstream. Like Dolby Digital, you can create your own DTS DATs or CDs but not mini disc or digital compact cassette. As with Dolby Digital, sound will normally come from all seven speakers in your system, but your receiver can produce sound in one (mono) to seven channels (see "Audio Modes under Operation"). 5 DTS NEO:6 ­ DTS Neo:6 is an advances matrix decoder. It will take any two-channel source and expand it into five or six channels, depending on the user's speaker layout. Two-channel sources include VHS tapes, broadcast television, stereo CDs and DVDs. DTS Neo:6 provides separate, optimized modes for stereo music materials and matrix surround motion picture soundtracks. DTS Neo:6 also decodes a center-surround channel from Extended Surround matrix soundtracks. DTS-ES (Extended Surround) - Extended Surround adds a center-surround channel to the existing 5.1-channel array. DTS-ES brings these soundtracks into the home in DTS quality and is the only home format that can deliver all 6.1 channels as discrete. DTS-ES is fully compatible with all types of multi-channel systems. All sounds will be heard, whether played back as discrete, matrix or on a 5.1 system. DTS 96/24 ­ More recording is being dome at a 96kHz sampling rate and at 24 bits. DTS has always had 24 bit capability, and DTS 96/24 adds the 96kHz capability. It is fully compatible with existing DTS encoders, which will output 96/24 tracks at 48 kHz. DTS 96/24 is the only system that provides 5.1 channels of 96/24 along with fullmotion video on DVD-Video and DVD-Audio (video zone). It is also compatible with all DVD-Video players, and is accessible through the digital output. DVD Audio (also referred to as MLP) - Meridian Lossless Packing (MLP) is a lossless coding system for highquality linear PCM audio. For DVD-Audio MLP performs lossless compression of up to 6 channels of up to 24-bit material sampled at rates between 44.1kHz and 192kHz. Lossless coding does not alter the final signal; it `packs' the audio data into a smaller rate and space. Currently, DVD Audio can only be delivered to your receiver via the analog 5.1 inputs. Sound will normally come from all seven speakers in your system, but your receiver can produce sound in one (mono) to seven channels (see "Audio Modes under Operation"). Home THX Cinema Processing - THX is an exclusive set of standards and technologies established by the world-renowned film production company, Lucasfilm Ltd. THX grew from George Lucas' personal desire to make your experience of the film soundtrack, in both movie and in your home theater, as faithful as possible to whatever the director intended. Movie soundtracks are mixed in special movie theaters called dubbing stages and are designed for playback in movie theaters using similar equipment and conditions. The soundtrack created for movie theaters is then directly put onto reproducible media, DVD, VHS tape Laser disc, etc. with no changes to account for playback in a smaller home theater environment. THX engineers developed patented technologies to accurately translate the sound from the movie theater environment into the home, correcting for the tonal and spatial errors that occur. While Home THX Cinema mode is active, THX processing is added after the Dolby Pro Logic, Dolby Pro Logic II, Dolby Digital or DTS decoder. Sound will normally come from all seven speakers in your system, but your receiver can produce sound in one (mono) to seven channels (see "Audio Mode"). Re-EqualizationTM - restores the correct tonal balance for watching a movie soundtrack in a small home theater. Timbre MatchingTM - filters the information going to the surround speakers so that they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning from the front to surround speakers. Adaptive DecorrelationTM - slightly changes one surround channel's time and phase relationship with respect to the other surround channel. This expands the listening position and creates a more spatial sense using only two speakers. 6 THX Surround EX TM - Dolby Digital Surround EX is a joint development of Dolby Laboratories and the THX division of Lucasfilm Ltd. In a movie theater, film soundtracks that have been encoded with Dolby Digital Surround EX technology are able to reproduce an extra channel, which has been added during the mixing of the program. This channel, called Surround Back, places sounds behind the listener in addition to the currently available front left, front center, front right, surround right, surround left and subwoofer channels. This additional channel provides the opportunity for more detailed imaging behind the listener and brings more depth, spacious ambiance and sound localization than ever before. When released to the home consumer market, movies that were created using the Dolby Digital Surround EX technology, may have a note to that effect on the packaging. A list of movies created using this technology can be found on the Dolby web site at http://www.dolby.com/. Only receiver and controller products bearing the THX Surround EX logo, when in the THX Surround EX mode, faithfully reproduce this new technology in the home. This product may also engage the "THX Surround EX" mode during the playback of 5.1 channel material that is not Dolby Digital Surround EX encoded. In such case the information delivered to the Surround Back channel will be program dependent and may or may not be very pleasing depending on the particular soundtrack and the tastes of the individual listener. Ultra 2 TM - THX Ultra2 is a breakthrough technology which allows an entertainment system to accommodate current and future multi-channel formats for both music and movies. THX Ultra2 specification provides uncompromised eight-channel playback of multi-channel program material, whether movie soundtracks or music over the widest possible seating area. In addition, all Ultra2 certified receivers and controllers must incorporate video switching capable of handling wide-bandwidth sources, including HDTV and progressive scan DVD, without degrading the picture. THX Ultra2 uses seven channels of amplification to playback multi-channel-encoded program for use in a single fixed seven-speaker/one subwoofer home theater system. In THX Ultra 2 Cinema mode or THX MusicMode, program material with 5.1 channels or more is auto-detected and additional processing is applied to blend the directional and ambient surround information for playback with two surround side speakers and two surround back speakers. Boundary Gain Compensation TM - Room boundaries such as walls and other acoustic obstacles may increase the perceived volume levels of low frequencies. Depending where the listener or the subwoofer is located, the listener may experience excess bass level. Boundary Gain Compensation allows a means to adjust for excessive bass resulting from a boundary gain effect. The Boundary Gain Compensation feature is designed to operate when used with a subwoofer certified to THX Ultra2 specifications Advanced Speaker Array TM (ASA) - In THX Ultra2 Cinema and THX MusicMode, ASA performs additional processing to optimize the use of surround side and surround back speakers in a home theater system. THX Ultra2 TM Cinema mode - Processing a multichannel digital signal (Dolby Digital, DTS, etc.), this mode plays back 5.1 and 6.1 encoded movies for use with up to 8 speakers to give an enhanced movie watching experience. In this mode, ASA processing technology is used to blend the surround side speakers with the surround back speakers to provide an optimal mix of ambient and directional surround sounds. THX's ASA circuitry will automatically detect DTS-ES (Matrix and 6.1 Discrete) and Dolby Digital Surround EX encoded soundtracks and apply the required ASA processing for playback using 8 speakers. THX MusicMode TM - DVDs encoded for music content typically have their surround sounds mixed differently than the surround sounds mixed for movie soundtracks. In this mode ASA processing technology is used to optimize the playback of 5.1 encoded music material, i.e. DTS, Dolby Digital and DVD-Audio, for playback using 8 speakers. THX MusicMode provides a stable wide rear soundstage with surround sounds best suited for music playback. 7 Bass Management - Dolby Digital and DTS-ES formats may contain up to 6 full range channels plus LFE. Only a system with six full-range (large) speakers plus a subwoofer can directly reproduce these formats. However, almost all commercially available center channel speakers are small and incapable of reproducing the lowest bass frequencies without distortion or even damage to the speaker. Many people also use small speakers in the rear of their system, while others use small speakers all around. Use of a subwoofer is almost mandatory when using five small speakers, but people with at least two large speakers may or may not choose to use a subwoofer. Some people may not use a center channel or surround speakers at all. In order to handle any possible combination of large, small, or missing speakers, a home theater system must contain good bass management, a concept often missing from two-piece systems where the Dolby Digital or DTS decoder is separate from the preamp. Your receiver contains a complete bass management system. You can use as few as two large front left and right speakers or two small left and right speakers plus a subwoofer or as many as seven full range speakers plus a subwoofer or any combination in between without missing any information. Wherever small speakers are used the bass management system prevents low bass information from going to that speaker ("high pass"). This bass information is rerouted to a speaker that can handle it, usually a subwoofer, but it can also send center, surround, or LFE bass to large front speakers if no subwoofer is available. When center or surround speakers are not used at all, the missing channel is sent ("down mixed") to the front speakers. Preamp - A preamp typically includes the capability to select from a number of sources, adjust volume levels and route the data to an amplifier. Your receiver includes a high quality preamp. Processor - A processor typically includes the capability to decode one or more surround formats, and convert between digital and analog as required. Your A/V receiver includes a high quality processor capable of decoding the surround formats described above. Zone - A zone is usually a room that has speakers installed in it. Your receiver includes a full preamp/processor for Zone 1 plus an additional analog stereo preamp for Zone 2. This allows, for example, watching a Dolby Digital movie in zone one while simultaneously using the built-in AM/FM tuner in another room. Amplifier - An amplifier takes the output of a preamp/processor and increases its level to that necessary to drive a speaker. Speakers - A surround sound system use to typically uses 5 speakers located left front, center front, right front, right surround, and left surround plus a subwoofer located anywhere in the room. With the new developments in surround technology from companies such as Dolby Laboratories, DTS, and Lucasfilm, it is now possible to improve spatial expressions with an additional channel of information for use with a 6th and/or 7th surround back speaker. Although best results are achieved using seven large speakers plus a subwoofer, this is not always practical. Excellent results can be achieved using small and/or fewer speakers, as long as you go through the set up procedures described later in the manual. Your receiver includes the capability of reproducing up to 6.1 channels of surround information. Component video vs. S-video vs. Composite video - Composite video is the oldest standard for color video. It combines the luminance (brightness or black-and-white) and chrominance (color) information onto a single conductor. These signals must be separated again for display resulting in some degradation of the video quality. S-video is a newer standard that uses separate conductors for the luminance (Y) and chrominance (C) information resulting in better video quality. Component video is the newest form of video introduced with DVD. This video format uses separate conductors for luminance (Y), red - luminance (R - Y), and blue - luminance (B Y). Using these signals a component video capable monitor allows for even better and higher resolution video quality. Your receiver is capable of switching composite, S-video and component signals, but it cannot convert between video types. In addition, your receiver is capable of switching between two pairs of component video inputs. 8 FRONT PANEL 5 B&K Components, Ltd.

Before you do that, take a few minutes to plan out how you want the receiver to fit into your audio/video system. Ask yourself the following questions: What source components do I want to connect to my receiver? (CD, VCR, etc.) What equipment will be receiving the audio and video? (TV monitor, Speakers, etc.) The answers to your questions determine how many cables you need to connect to the back of the receiver. Good preplanning equals great sound. Keep these recommendations in mind: List all components in your system and indicate which jacks of the receiver each component will be connected to. Your receiver has seven sets of inputs. It is convenient to connect a DVD player to the input labeled DVD or a VCR to the input labeled V1 or TAPE, etc. However, your equipment may differ from the labeling on the back of your receiver. In most cases you can connect any type of source to any input (see FREQUENTLY ASKED QUESTIONS). For example, if you don't have a satellite receiver you can connect a DAT player or a second cassette deck to SAT. You can also reprogram the source name that will appear on your receiver's front panel and on-screen display (see SYSTEM SETUP - INPUTS) Also note the length of the cable for each component's connection and describe how it should be routed or draw your routing scheme below your list. You may want to label each cable with a name or number at both ends. Use high quality connections to maintain high quality audio and video. Think about the type and length of cable you need and obstacles in the cable's path (doorways, furniture, walkways, etc.). To decide which ones are right for you talk to your dealer about the various cable products that are available. For safety, keep all cables out of high traffic areas (hallways or doorways) and away from equipment that radiates power, including amplifiers, power cords, heaters, etc. If you might expand your audio/video system later, keep these ideas in mind as you plan current cable runs. To provide the best tuner reception, make sure the antenna is at least several feet away from the receiver and any other equipment that may produce high frequency interference such as Personal computers, CD players, halogen lamps, etc. Take a look at the back panel of the receiver. You will notice that the RCA-type audio input and output connectors are identified by colors, red for right channel and white for left channel audio. Red/White/Grey identifies the surround outputs. Red/Green/Blue identifies component video input and output connectors. Composite video input and output connectors are identified by yellow. Coaxial digital inputs are identified by orange. 12 AUDIO / VIDEO CONNECTIONS Connecting your analog sources to your receiver Audio / Video source - connecting a DVD/VLD player to the receiver's analog inputs. Use the same instructions for connecting to other audio / video sources such as a satellite receiver, cable box, etc. See Connecting Video for use with other than composite and S-video (Omit the video connections for an audio-only component such as a CD player.) Attach one end of the audio interconnect cable to the left audio output on the DVD/VLD player, then attach the other end to the left (white) DVD/VLD audio input on the receiver. Repeat for the right (red) audio connection. Attach one end of the composite video interconnect cable to the video out on the DVD/VLD player, then attach the other end to the yellow video input on the receiver labeled DVD/VLD. Repeat for the S-video connections if you are using S-video. ZA DVD S-Video input from DVD output Composite video input from DVD output Left audio input from DVD output Right audio input from DVD output LINE INPUTS S-Video output to monitor input Composite video output to monitor input S BACK Video Monitor - Attach one end of the composite video interconnect cable to the video input on the monitor, then attach the other end to the yellow video output on the receiver's ZONE OUTPUTS. Repeat for the S-video connections if you are using S-video. Dual zone operation requires connections be made to (ZA) for Zone 1 (A), and (ZB) for Zone 2 (B). VCR or audio recorder - connect a VCR to V1. Use the same instructions for connecting to the V2 and TAPE analog inputs. If connecting a cassette deck or other audio-only recorder then omit the video connections. V1 V1 S-Video output to VCR input Composite video output to VCR input Left audio output to VCR input Right audio output to VCR input LINE OUTPUTS LINE INPUTS S-Video input from VCR output Composite video input from VCR output Left audio input from VCR output Right audio input from VCR output Attach one end of the audio interconnect cable to the left audio output on the VCR, then attach the other end to the left (white) V1 audio input on the receiver. Repeat for the right (red) audio connection. Attach one end of the composite video interconnect cable to the composite video output on the VCR, then attach the other end to the yellow video input on the receiver labeled V1. Repeat for the S-video connections if you are using S-video. Attach one end of the audio interconnect cable to the left audio input on the VCR, then attach the other end to the left (white) V1 audio output on the receiver. Repeat for the right (red) audio connection. Attach one end of the composite video interconnect cable to the composite video input on the VCR, then attach the other end to the yellow video output on the receiver labeled V1. Repeat for the S-video connections if you are using S-video. 13 Component Video - in addition to S-video and composite video switching, your receiver provides two sets of component video inputs for DVD and TV/DBS type inputs, and one set of component video outputs. Your receiver's component video connections are passive to minimize the possibility of video format compatibility issues. Use the same instructions to connect a second (TV/DBS) component video device.

Repeat for the surround left (white) and surround right (red) audio connection. 14 DIGITAL CONNECTIONS Connect digital inputs (DVD, VLD, etc.) to the receiver. You will need either coaxial or optical digital inputs to play Dolby Digital (AC-3) or DTS surround sound processing. Digital connections are also recommended for PCM sources. If your source has both optical and coaxial outputs connect only one. Coaxial digital inputs - standard RCA type connectors. Attach one end of your digital coaxial cable to your source coaxial digital out and the other end to the appropriate receiver coaxial digital (orange) input. Optical digital inputs - First, remove the cap on the optical digital input. Save the cap. Attach one end of your digital optical cable to your source and the other end to the appropriate digital input on the back of the receiver. ZA OUT COAX DIGITAL TV V2 V1 Coax digital input from DVD output ZB OUT SAT CD DVD OPTICAL DIGITAL CD DVD V2 SA T V1 Optical digital output from source Connecting A Laser disc Player - Dolby Digital (AC-3) laser discs use a special technique called ACDT-1 3 RF to encode the Dolby Digital bitstream. If the laser disc player is capable of playing back Dolby COAX DIGITAL Digital discs it will have a separate output for this TV V2 V1 bitstream in addition to the normal coaxial and/or optical outputs. Do not connect the AC3-RF output MAIN COAX AC-3 RF directly to your receiver. The AC-3 RF bitstream OUTPUT INPUT INPUT must first be converted to a normal (non-RF) Dolby SAT CD DVD Digital type signal. It is recommended that a B&K DT-1 be used to convert and select between the Coax digital input Laser's AC-3 RF and PCM/DTS signals. The output from VLD output from a DT-1 will automatically select between the connected PCM/DTS bitstreams and the converted AC-3 RF input AC-3 RF Dolby Digital signal. Other AC-3 RF to from VLD output Dolby Digital decoders may not make this switch automatically. Connect the laser disc's AC3-RF output to the DT-1's AC-3 RF input. Connect either the laser disc player's PCM coaxial or optical digital output (not both) to the DT-1's coaxial or optical input. Connect the DT-1's coaxial output to the desired coaxial digital input on your receiver. Digital Outputs - Separate and independent coax digital outputs are available for Zone 1 and Zone 2. Connect to a digital recorder (CD-R, mini disc, DAT, personal computer, etc.) These signals are the same as the incoming digital signal from the selected source on each zone. If your digital recorder has both optical and coaxial inputs you need only connect one. Zone 1 selected digital input is converted to both coaxial and optical. You may connect one digital recorder to the optical output and another recorder to the coaxial. Zone 2 digital output is coax.

The AVR 315 receiver allows THX Surround EX compatibility via two Surround Back `S BACK' processor outputs. Here is a typical surround output setup: ZA AUDIO OUT SUB CENTER Connect to the Subwoofer 'SW' power amplifier input Connect to the Surround Left 'Sl' power amplifier input Connect to the Surround Right 'Sr' power amplifier input Connect to the Center power amplifier input Connect to the Left Front power amplifier input Connect to the Right Front power amplifier input Connect to Zone 1 (A) composite video monitor input Connect to the Surround Back Left 'Sbl' power amplifier input Connect to the Surround Back Right 'Sbr' power amplifier input S BACK SURR FRONT Subwoofer Output - Connect an RCA cable from the receiver's SW output (part of the surround outputs. If your subwoofer does not contain its own amplifier (powered subwoofer) you will need to acquire the use of an external power amplifier. Connect the external amplifier's speaker output to your subwoofer. 16 SPEAKER OUTPUTS L C R FRONT LEFT (-) (+) (-) (+) CENTER FRONT RIGHT (-) (+) SURROUND LEFT SURROUND RIGHT CENTER SURROUND BACK SURROUND BACK LEFT RIGHT FRONT LEFT FRONT RIGHT PLUS PLUS PLUS PLUS PLUS PLUS PLUS MINUS MINUS MINUS MINUS MINUS MINUS MINUS Sl (-) (+) Sr (-) (+) Sbl (-) (+) SURROUND LEFT Sbr (-) (+) SURROUND RIGHT SURROUND BACK LEFT SURROUND BACK RIGHT Five-way binding posts are provided, one pair for each channel.

The plug must be wired as tip (+) and the long barrel section (-). The Control outputs are programmable for each source in your system (see "Advanced Setup"). However, the receiver provides the following factory preprogrammed setup that should serve for most standard system applications. Control 1 - HEADPHONE. On (+12 VDC) when Zone 1 is on and not in Headphone mode, off when Zone 1 is off or in Headphone Mode. This mode may be used for controlling external amplifiers or powered subwoofers in Zone 1. Control 2 - Zone 2. On (+12 VDC) when Zone 2 is on, off (0 VDC) when Zone 2 is off. This mode is used for controlling external amplifiers, projection screens, etc. in Zone 2. Control 3 - Z1 + Z2. On (+12 VDC) when Zone 1, Zone 2, or both zones are turned on. Off (0 VDC) when both zones are off. Control 4 -REMOTE. It will repeat a received 38 kHz modulated IR signal. The receiver will transmit received IR signals even in sleep mode. Note - The control outputs can output a maximum of 50 mA. Check to see that the source you are connecting to the control out requires 50 mA or less current. WARNING - Not all manufacturers adhere to the +12 VDC control specification. Check to see if your sources control inputs are +12 VDC compatible. Do not connect your receiver's control outputs to a source with control or remote inputs rated at +5 VDC or other voltage rating. Damage to your source may result. IR Inputs - Your receiver can be controlled by a directly connected IR repeater system in combination with or in place of the supplied remote control. Connect your IR input cable to the receiver using a mono 3.5 mm jack shown above. The plug must be wired as tip (+) and the long barrel section (-). The inputs are standard 38kHz modulated IR type with a voltage range of +5 to +12 VDC. 18 FREQUENTLY ASKED QUESTIONS My collection of equipment differs from the labels on the back of my receiver, how can I hook them up? Your receiver provides 5 identical sets of inputs - V1, V2, DVD, CD, and SAT. Each of these has analog audio, composite video, S-video, coaxial digital audio, and optical digital audio. It is convenient to connect components as labeled on the back of your receiver, but since all the inputs are identical, you can connect any compatible source to any set of inputs. For example, you can connect a DAT player to V1 instead of a VCR. You can program your receiver to display any 5 character name for any input (see System Setup - Inputs). The sixth input, TV, is identical to the others except that there is no optical digital. You can also connect portables to any other coaxial digital input using adapters or special cables. If you have a source with only optical digital output don't connect it to TV. The seventh input, TAPE, has analog audio, composite video and S-video, but has no digital inputs. It is primarily intended for analog recorders such as VCRs or cassette decks. If you have a three-head cassette or reel-to-reel tape deck you will prefer the TAPE input since it allows a full tape monitor capability. Tape monitor allows you to listen to what is actually on the tape as you are recording it. The V2 input also provides full tape monitor capabilities for Zone 2. If you don't use Zone 2 you can use V2 as a second independent analog tape monitor loop. V1 includes a line level output but does not provide true tape monitor capability. My DVD player (or other source) has both optical and coaxial digital outputs. Should I connect both? No, connect only one digital cable per source. Do I need an AC-3 RF demodulator (B&K DT-1 or equivalent) to playback Dolby Digital DVDs? No, this is required only for Dolby Digital laser discs. Do I need an AC-3 RF demodulator (B&K DT-1 or equivalent) to playback DTS laser discs? No, this is required only for Dolby Digital laser discs. Do I need to connect both analog and digital audio from my DVD player (or other digital audio source) to the receiver? In general, it is simpler to connect both. However, if you can meet all of the following criteria you need only connect digital: 1. I do not use Zone 2. (Zone 2 is analog only - if you use Zone 2 you must connect both left and right analog to hear audio.) 2. I do not own any old laser discs. (Early laser discs contained only analog audio tracks - you must connect both left and right analog audio to play these back.) 3. I do not use Tape Monitor. (It is possible to tape digital-only sources. However, if you wish to listen directly to the tape as you are recording - you must connect both left and right analog audio - the tape monitor loops are strictly analog.) If the tape monitor loop is strictly analog, how do I make an analog recording of a digital-only source? Do not select TAPE. Select the source you wish to record. Select STEREO 9, the LtRt mode. If that source is digital, the converted digital-to-analog will appear at the tape and V1 outputs. V2 out, like Zone 2 out, is analog only. (See Operation - Audio Mode.) I want to make direct digital recordings from my CD player (or other digital source) on my CD Recorder, DAT (or other digital recorder). Can my receiver make this connection for me? Yes, your receiver's digital outputs act much like the analog tape outputs. When you select a source, if that source has a digital connection to your receiver, then that digital signal will appear on the receiver's coaxial and optical digital outputs. Simply connect all of your sources digital outputs to your receiver's digital inputs. You can then connect up to three digital recorder inputs to your receiver's three digital outputs. 19 My laser disc player (or other digital source) has only optical output, but my CD recorder (or other digital recorder) has only coaxial input. Do I need some sort of converter to make direct digital recordings? No, your receiver will convert optical to coaxial and coaxial to optical. The currently selected digital input (optical or coaxial) will appear at both of the receiver's digital outputs (optical and coaxial). Do I need to connect both analog and digital audio from my receiver to my CD, DAT, MD, etc. recorder? In general, yes. If all of the sources you wish to record are digital, then you need only connect digital to your recorder. However, your receiver does not provide digital outputs for non-digital inputs. If you wish make a digital recording from an analog-only source you must also connect analog from your receiver (Tape or V1 out) to your recorder. Can I connect a phonograph directly to my receiver? No, you will need a separate outboard phono preamplifier. The output of the phono preamp can then be connected to any analog input on your receiver. We recommend our Phono 10 phono preamp. In addition to its superb analog audio processing, it has an option for S/PDIF coax output. Talk to the dealer where you purchased your receiver. Do I need to connect both S-video and composite video to my receiver? If all of your video equipment has S-video then you need only connect S-video. S-video is a higher quality video format and you will probably not want to use composite. If all or most of your video equipment is composite then it is simplest to just connect the composite and omit S-video. Can I connect mixed composite and S-video sources? Yes, but your receiver will not convert S-video to composite or composite to S-video. If your monitors and VCRs accept only composite video then there is no point in connecting S-video from other sources. If you use mixed S-video and composite sources you must connect both S-video and composite to your monitors and VCRs. You will need to change your monitor or VCR S-video / composite inputs manually when you change sources. This can normally be done via the monitor's or VCR's remote control (or the supplied universal remote). Some monitors or VCRs may require you to physically disconnect S-video before they will accept composite video. Some monitors are capable of automatic switching between S-video and composite. Your receiver must be setup properly in order to work with auto switching monitors - refer Setup Displays. To assist you, the receiver's on-screen display will tell you what video is currently selected whenever you change sources or hit the SEL (remote) or ENTER (remote or front panel) key, but it cannot switch your monitor or VCR input for you. If you are watching S-video, but the source is composite video only, you will see "Switch Monitor to Composite" on your Monitor. If you are watching Composite video but your source is S-video only, you will see "Switch Monitor to S-video" on your monitor. These displays appear only if your receiver is setup for manual monitors. Can I connect mixed composite and S-video monitors and VCRs? Yes, but you must connect both S-video and composite from all of your sources - your receiver will not convert between S-video and composite. Refer to the previous question if not all of your sources have both Svideo and composite outputs. For example, it is common to have an S-video monitor and a composite VCR. Connect the monitor to the Zone 1 S-video and composite outputs and the VCR to the V1 or TAPE composite output. The composite inputs will appear at the composite outputs for TAPE and V1. (The S-video inputs also appear at the TAPE and V1 Svideo outputs, but, in this example, they are not connected.) To prevent feedback, TAPE IN will not appear on TAPE OUT and V1 IN will not appear on V1 OUT - this also applies to the audio outputs. Zone 2 works the same for Zone 2 OUT and V2 OUT with feedback prevention on V2. Things get a bit more complicated for the Zone 1 output because it contains your receiver's internal onscreen display system. You must be sure that you tell your receiver if you have a monitor which can automatically switch between S-video and composite outputs, or one which must be manually switched (see Setup Displays). 20 SETUP For best results, perform the following set up procedure when you initially install your receiver and anytime you change or add sources, speakers, etc. or when you rearrange your listening area THE MENU SYSTEM Setup of your receiver will require you to navigate through the menu system. We recommend that you use a video monitor connected to the Zone 1 output along with the remote control provided with your receiver. It is also possible to set up your receiver from the front panel. Do not leave your video monitor on with the receiver in the menu system for long periods of time. This can result in permanently burning the menu display into your monitor's screen. This would take several hours so there is no danger of it happening during normal setup procedures. The following are general instructions for using the menu system. A complete guide to the menu system is included at the back of this manual. MENU - If you are not already in the menu system, the MENU button will activate the menu system. Once you are in the menu system, the MENU button will return you to the next higher-level menu or, if you are already at the highest level, it will exit from the menu system. UP/DOWN ARROWS - Once you are in the menu system, use the UP/DOWN ARROWS to move to the desired menu selection. The currently active menu line is highlighted in a contrasting color. SEL (remote) or ENTER (remote or front panel) - Some menu selections cause another menu to be activated. Use the UP/DOWN ARROWS to move to the desired menu line. Pressing SEL or ENTER will activate the next menu. NUMERIC KEYS (remote only) - From the remote control you may also go directly to a menu line by typing the corresponding line number. If there is another menu below that line it will be activated immediately (no ENTER required).

Pressing the LEFT/RIGHT ARROWS will change the setting. There are no LEFT/RIGHT ARROWS on the front panel. While in the menu system, the VOLUME KNOB acts as the LEFT/RIGHT ARROWS. This means that you will not be able to adjust the volume from the front panel while in the menu system. The remote control volume will work in most menus. TEXT EDITING - some menu selections will require you to edit text. Use the UP/DOWN ARROWS to change the current (blinking) character. Use the LEFT/RIGHT ARROWS (or VOLUME KNOB) to move to another character position. EXIT (remote only) - From the remote control you may instantly EXIT the menu system. UNIVERSAL REMOTE - Remember that when you press a source button (DVD, CD, etc.) the remote now controls the selected device. To return control to your receiver, you must press B&K or AUDIO. ALWAYS check that your remote is set to B&K or (AUDIO) before attempting to control your receiver. B&K or (AUDIO) will be displayed in the remote's LCD window. 21 SYSTEM SETUP You should always perform System Setup after first installing your receiver and after adding/changing speakers or sources or rearranging your listening area.

This is the most important setup procedure you will perform. The receiver comes from the factory setup for 7 small speakers and a subwoofer. If this does not match your speakers then audio information will be lost. For example, if you do not currently have a center channel speaker and you do not perform this setup procedure, the center channel information will be lost. If you perform this setup correctly, the receiver will know that you have no center channel speaker and send this information to your front left and right speakers (along with the normal front left and right information) so no audio information is lost. Speaker Size Speaker size generally refers to the size of your speakers. Audio material, particularly Dolby Digital and DTS movies, often contain large amounts of bass. If this bass information is sent to small speakers that are incapable of reproducing so much bass, then the bass information will be lost or distorted. TOO MUCH BASS MAY DAMAGE MANY SMALL SPEAKERS. By telling your receiver the size of your speakers, it will be able to intelligently route the bass to speakers that can reproduce it correctly. Typically, all bookshelf or satellite speakers are considered small. Smaller floor standing speakers with single woofers 8" or less should also be considered small. Floor standing speakers with 10" or larger woofers or multiple smaller woofers may be considered large. These are general guidelines only - if you are unsure consult your speaker manufacturer or check with the dealer if they are unsure. If you have all small speakers we strongly recommend use of a subwoofer. If your front left and right speakers (or more) are large then you may not require a subwoofer, but you may still get better results using a subwoofer, especially with Dolby Digital and DTS movies. All THX certified speakers are small, regardless of their physical size, and should be used in audio systems along with a subwoofer. 22 Set the size for your front left and right, `L' and 'R' speakers - You must have front speakers. 1 2 3 4 5 SETUP SPEAKERS Speaker Size Speaker Location Speaker Levels Crossovers + LFE Room Equalization next item SEL select MENU setup system 1 2 3 4 5 6 SETUP SPEAKER SIZE Front Large Center Small THX Surround Small THX Surround Back None Subwoofer Yes THX THX Ultra 2 Sub Yes next item adjust MENU setup speakers SPEAKERS SIZE FRONT Large From Remote 1 2 3 4 À(PAUSE) or §(STOP) SEL or ENTER À(PAUSE) or §(STOP) ¶(REW) or ·(FF) From Front Panel (UP) or (DOWN) (ENTER) (UP) or (DOWN) VOLUME KNOB Action move to Speaker Size activate SETUP SPEAKER SIZE move to Front choose speaker size Subwoofer None Front Bass is *Front Hi-Pass to Front Front Full Range to Front Front setting Small THX Large Subwoofer Ultra Front Bass to SW Front Hi-Pass to Front Front Bass to SW Front Full Range to Front Subwoofer Yes THX Front Bass to SW Front Hi-Pass to Front Front Full Range to Front Set the size for your center `C' speaker 1 2 3 4 5 6 SETUP SPEAKER SIZE Front Large Center Small THX Surround Small THX Surround Back None Subwoofer Yes THX THX Ultra 2 Sub Yes next item adjust MENU setup speakers CENTER SMALL From Remote 1 2 À(PAUSE) or §(STOP) ¶(REW) or ·(FF) Subwoofer Ultra From Front Panel (UP) or (DOWN) VOLUME KNOB Subwoofer Yes THX Action move to Center choose speaker size Subwoofer None Front Large Center Full to Front Center Bass is *Center Hi-Pass to Center Center Full to Center Subwoofer None Front Small Center Bass is *Center Hi-Pass to Front Center Bass is *Center Hi-Pass to Center Center Full to Center Center setting None Small THX Large Center Bass to SW Center Hi-Pass to Front Center Bass to SW Center Hi-Pass to Center Center Bass to SW Center Full to Center Center Bass to SW Center Hi-Pass to Front Center Bass to SW Center Hi-Pass to Center Center Full to Center 23 Set the size for your surround left and right, `Sl' and `Sr' speakers 1 2 3 4 5 6 SETUP SPEAKER SIZE Front Large Center Small THX Surround Small THX Surround Back None Subwoofer Yes THX THX Ultra 2 Sub Yes next item adjust MENU setup speakers SURROUND SMALL From Remote 1 2 À(PAUSE) or §(STOP) ¶(REW) or ·(FF) From Front Panel (UP) or (DOWN) VOLUME KNOB Action move to Surround choose speaker size Surround setting None Small THX Large Subwoofer Ultra Surround Bass to SW Surround Hi-Pass to Front Surround Bass to SW Surround Hi-Pass to Surround Surround Bass to SW Surround Full to Surround Subwoofer Yes THX Surround Bass to SW Surround Hi-Pass to Front Surround Bass to SW Surround Hi-Pass to Surround Surround Full to Surround Subwoofer None Front Large Surround Full to Front Surround Bass is *Surround Hi-Pass to Surround Surround Full to Surround Subwoofer None Front Small Surround Bass is *Surround Hi-Pass to Front Surround Bass is *Surround Hi-Pass to Surround Surround Full to Surround Set the size for your surround back left and right, `Sbl' and `Sbr' speakers SETUP SPEAKER SIZE Front Large Center Small THX Surround Small THX Surround Back None Subwoofer Yes THX THX Ultra 2 Sub Yes next item adjust MENU setup speakers 1 2 3 4 5 6 SUR BACK None From Remote 1 2 À(PAUSE) or §(STOP) ¶(REW) or ·(FF) From Front Panel (UP) or (DOWN) VOLUME KNOB Action move to Surround Back choose speaker size 24 Surround Back setting None 1 Small Subwoofer Ultra Subwoofer Yes THX Subwoofer None Front Large Surround Full to Front Sb Bass is *Sb Hi-Pass to Surround Back Left Sb Full to Surround Back Left Sb Bass is *Sb Hi-Pass to Sbl and Sbr Sb Full to Sbl and Sbr Subwoofer None Front Small Surround Bass is *Surround Hi-Pass to Front Sb Bass is *Sb Hi-Pass to Surround Back Left Sb Full to Surround Back Left Sb Bass is *Sb Hi-Pass to Sbl and Sbr Sb Full to Sbl and Sbr Surround Bass to SW Surround Hi-Pass to Front Sb Bass to SW Sb Hi-Pass to Surround Back Left Sb Bass to SW Sb Full to Surround Back Left Sb Bass to SW Sb Hi-Pass to Sbl and Sbr Sb Bass to SW Sb Full to Sbl and Sbr Surround Bass to SW Surround Hi-Pass to Front Sb Bass to SW Sb Hi-Pass to Surround Back Left Sb Full to Surround Back Left Sb Bass to SW Sb Hi-Pass to Sbl and Sbr Sb Full to Sbl and Sbr 1 Large 2 Small THX 2 Large Setup your subwoofer `SW' - In the table above, you have the flexibility to choose how bass information is distributed to your speakers only if you have large speakers and a subwoofer as part of your home theater speaker system. For example, selecting the "Front Large" and "Subwoofer Yes THX" options, bass from the front left and front right channels will go ONLY to the front left and front right speakers. Bass going to the subwoofer will only come from the LFE channel and any channels with speakers that you have designated as "Small". This selection is preferred by THX. However, selecting the "Front Large" and "Subwoofer Ultra" options, you will send the bass from the front left and right channels to the front left, right AND subwoofer speakers simultaneously. To decide which setting is best for your room, once you have positioned all of your speakers, choose the option that gives you the most solid sounding bass. Note: when the subwoofer is set to None, bass is redirected to remaining large speakers. When no speakers are set to Large, and the subwoofer is set to None, bass information is lost. 1 2 3 4 5 6 SETUP SPEAKER SIZE Front Large Center Small THX Surround Small THX Surround Back None Yes THX Subwoofer Yes THX THX Ultra 2 Sub Yes next item adjust MENU setup speakers SUBWOOFER YES From Remote 1 2 3 À(PAUSE) or §(STOP) ¶(REW) or ·(FF) MENU From Front Panel (UP) or (DOWN) VOLUME KNOB MENU Action move to Subwoofer choose the desired subwoofer setting return to SETUP SPEAKERS 25 Subwoofer Setting None Yes THX Ultra Front Large LFE + Bass to Front LFE + Bass to SW Front Bass not Duplicated LFE + Bass to SW Front Bass is Duplicated Center Large LFE + Bass to Center LFE + Bass to SW Center Bass not Duplicated LFE + Bass to SW Center Bass is Duplicated Surround Large LFE + Bass to Surround LFE + Bass to SW Surround Bass not Duplicated LFE + Bass to SW Surround Bass is Duplicated Surround Back Large LFE + Bass to Surround Back LFE + Bass to SW Sb Bass not Duplicated LFE + Bass to SW Surround Back Bass is Duplicated Note: The subwoofer setting affects the routing of front, center, and surround bass information as shown previously.

This setting allows a means to adjust for excessive bass resulting from a boundary gain effect. Room boundaries such as walls and other acoustic obstacles may increase the perceived volume levels of low frequencies. Depending where the listener or the subwoofer is located, the listener may experience excess bass level. THX Ultra2 allows for Boundary Gain Compensation to reduce the boundary gain effect and allows a more natural listening environment. Select "Yes" if your subwoofer conforms to the THX Ultra2 standard or if the playback capability of its bass range extends down to 20 Hz. Otherwise, select "No." SETUP SPEAKER SIZE Front Large Center Small THX Surround Small THX Surround Back None Subwoofer Yes THX THX Ultra 2 Sub No next item adjust MENU setup speakers 1 2 3 4 5 6 ULTRA U2 SUB No From Remote 1 2 3 À(PAUSE) or §(STOP) ¶(REW) or ·(FF) MENU From Front Panel (UP) or (DOWN) VOLUME KNOB MENU Action move to THX Ultra 2 Sub choose the desired THX Ultra 2 Sub setting return to SETUP SPEAKERS 26 Speaker Location Ideally your speakers will be the same distance away from your listening area. However, physical limitations usually require placing the speaker in other than optimum locations. Your receiver contains a means to electronically move each speaker's location. This allows for superior reproduction of the directional cues available during the playback of movie or music. Measure the distance in feet to your speakers and set each speaker location setting to this distance. Your receiver will electronically "move" each speaker to maintain correct time alignment with the listening position. You may also change the units to meters, if you prefer.

For best results it is important that you perform this calibration when you initially install your receiver, whenever you change speakers, and whenever you rearrange your listening area. The following adjustment must be done for proper room calibration to THX reference level. Sit or place the SPL (Sound Pressure Level) meter in your normal listening spot. Check that you are in SETUP SPEAKERS and that your remote is in B&K mode. Note that if you have turned a speaker OFF in the SPEAKER SIZE SETUP menu then you will not be able to select that speaker in the SETUP SPEAKER LEVELS menu. Set the SPL meter to use 75 dB SPL, C Weighting and SLOW response. Adjust each speakers level up or down to achieve the desired THX reference level of 75 dB SPL. Note: if you must do this adjustment with out the aid of an SPL meter, you may do it by ear and adjust each speaker for equal volume. You may wish to go through the speakers several times to get a reasonable result. Also note that the VOLUME on the remote will not function in this menu. 1 2 3 4 5 SETUP SPEAKERS Speaker Size Speaker Location Speaker Levels Crossovers + LFE Room Equalization SETUP SPEAKER LEVELS Left Center Front +12.0 -11.5 +9.5 Right Front +12.0 -11.5 +9.5 Surround +12.0 +12.0 Back +12.0 +12.0 Subwoofer +12.0 next item adjust MENU setup speakers next item SEL select MENU setup system SPEAKER LEVELS LEFT Front +12.0 From Remote 1 2 3 4 5 6 7 8 À(PAUSE) or §(STOP) SEL or ENTER À(PAUSE) or §(STOP) ¶(REW) or ·(FF) À(PAUSE) or §(STOP) ¶(REW) or ·(FF) repeat 5-6 for each speaker MENU From Front Panel (UP) or (DOWN) (ENTER) (UP) or (DOWN) VOLUME KNOB (UP) or (DOWN) VOLUME KNOB repeat 5-6 for each speaker MENU Action move to Speaker Levels activate SETUP SPEAKER LEVELS move to Left Front adjust left level to a convenient reference level move to Center adjust center level to match left repeat until all levels match return to SETUP SPEAKERS Crossovers + LFE Usually these settings may be left set to the factory defaults. However, your receiver allows `fine tuning' of the system parameters most useful in setting up a high-end audio system. Set the high and low pass filters' crossover frequency - This sets the frequency at which bass tones are removed from the small main speakers and sent to the subwoofer. If you use very small main speakers you may wish to raise the crossover above 80 Hz. You may get better results with fairly large speakers by setting them to small and using a low crossover frequency so only the lowest tones are sent to the subwoofer. THX certified speakers are specifically designed for use with an 80 Hz crossover setting. 28 1 2 3 4 5 SETUP SPEAKERS Speaker Size Speaker Location Speaker Levels Crossovers + LFE Room Equalization 1 2 3 4 5 SETUP CROSSOVERS + LFE Crossover 80.0 Hz THX High Pass 12.0 dB THX Low Pass 24.0 dB THX LFE Level -20.0 dB Subwoofer Phase Invert next item SEL select MENU setup system next item adjust MENU speaker setup crossovers +lfe CROSSOVER 80 HZ From Remote 1 2 3 4 À(PAUSE) or §(STOP) SEL or ENTER À(PAUSE) or §(STOP) ¶(REW) or ·(FF) From Front Panel (UP) or (DOWN) (ENTER) (UP) or (DOWN) VOLUME KNOB Action move to Crossovers + LFE activate SETUP CROSSOVERS + LFE move to Crossover adjust frequency to desired value Set the high pass filters slope - A crossover doesn't simply send all content above 81 Hz to the main speakers and all content below 79 Hz to the sub. Instead there is a gradual transition. The crossover point is the frequency at which the amount of information in the sub and main speaker is equal. The crossover slope determines how gradual or abrupt this transition occurs. More gradual slopes generally result in a smoother transition from main to sub. However, gradual transitions can cause distortion in small main speakers because too much bass is sent to them. Gradual transitions with higher crossover settings can also cause the perceived location of a sound to move from the correct main speaker to the sub's location. THX speakers are specifically designed to use a 24 dB slope for the subwoofer and a 12 dB slope for the main speakers.
