Your purchase of an ADP303 places you in the vanguard of home theater listeners. The ADP303's advanced circuitry decodes the Dolby Digital (AC-3) signals from standard laser discs, the latest DVD players and other future digital audio sources to deliver six separate, discrete audio channels. The realism of AC-3 finally allows you to hear motion picture soundtracks and music videos with the digital clarity of the best first run movie theater. While complex systems are hard at work within the ADP303 to decode the digital audio, hook-up and operation are simple. However, to obtain the maximum enjoyment from your new decoder we urge you to take a few minutes to read through this manual. This will ensure that connections to source playback units, receivers or amplifiers and other external devices are made properly. In addition, a few minutes spent learning the functions of the various controls will enable you to take advantage of all the processing power the ADP303 is able to deliver. If you have any questions about this product, it's installation or operation, please contact the retailer or custom installer who sold you the product. They are your best source of local information. IMPORTANT SAFETY INFORMATION Verify Line Voltage Before Use Your ADP303 has been designed for use with 230 volt AC current. Connection to a line voltage other than that for which it is intended can create a safety and fire hazard, and may damage the decoder. If you have any questions about the voltage requirements for your specific model, or about the line voltage in your area, contact your selling dealer before plugging the unit into a wall outlet. Do Not Use Extension Cords To avoid safety hazards, use only the power cord supplied with your unit. If a replacement cord is used, make certain that it is of similar gauge. We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets or place heavy objects on them. Damaged power cords should be replaced immediately with cords meeting factory specifications. Handle the AC Power Cord Gently When disconnecting the power cord from an AC outlet, always pull the plug, never pull the cord. If you do not intend to use the decoder for any considerable length of time, disconnect the plug from the AC outlet. Do Not Open The Cabinet There are no user serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modification to the product will void your warranty. If water or any metal object such as a paper clip, wire or a staple accidentally falls inside the unit, disconnect it from the AC power source immediately, and consult an authorized service station. Installation Location · To assure proper operation, and to avoid the potential for safety hazards, place the unit on a firm and level surface. When placing the unit on a shelf, be certain that the shelf and any mounting hardware can support the weight of the product. · Make certain that proper space is provided both above and below the unit for ventilation.

We suggest that you save the carton and packing materials for use in shipping if you move or should the unit ever need repair. To minimize the size of the carton in storage, you may wish to flatten it. This is done by carefully slitting the tape seams on the bottom and collapsing the carton down to a more two dimensional appearance. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag. If you do not wish to save the packaging materials, please note that the carton and other sections of the shipping protection are recyclable. Please respect the environment and discard those materials at a local recycling center. When positioning your ADP303 in its final location, make certain that any shelf or stand is capable of supporting its weight, and that there is adequate ventilation on all sides, as well as on the top and bottom. Do not place CD's, record jackets, owner's manuals, or other paper on top of, or beneath the unit. This will block air flow and create a potential fire hazard. If the unit is to be enclosed in a cabinet or rack, make certain that there is adequate air circulation, with a means provided for hot air to exit, and for cool air to be brought in. WHAT IS DOLBY DIGITAL? Dolby Digital, or AC-3 as it is often referred to, is a totally new generation of multi-channel digital audio technology. Using advanced circuit designs and specially developed compression techniques, AC-3 delivers significant advances over previous multi-channel systems: it delivers noise free, wide bandwidth sound and it includes six separate audio channels. AC-3 evolves from Dolby Laboratories' constant research into new ways to deliver high quality audio for theatrical motion picture presentation and transmission via satellite and telecommunications links. In fact, the "AC" in AC-3 stands for "Audio Coding," the technique used in Dolby Digital for data compression. The ADP303 digital demodulator/ decoder brings that same 5.1 channel high quality sound that accompanies many major motion pictures into your home when used with a compatible laser disc player, as well as from future Dolby Digital sources such as DSS, Digital Video Disc (DVD) and High Definition Television (HDTV). For today's Laser Disc systems the digital audio signal is recorded as a modulated RF signal, similar to the signals used for FM and TV broadcasts. That is why connections to a laser disc are made through an "RF" input. New technology products such as DVD will feature direct data outputs, and they are connected directly to the ADP303's decoding circuitry, without the need for the demodulator stage. Both Coaxial and Optical data inputs are available. Traditional "stereo" recordings consist of two channels, left and right, even though the original intent of sound engineers was to have a multitude of channels available to present a realistic audio soundfield. Unfortunately, early recording techniques for vinyl records and optical movie soundtracks were limited to two channels. Dolby Surround was the technology that broke the two channel barrier, by placing two additional channels within the left and right signals. Those two additional channels presented center channel information, primarily for movie dialog, and a single, mono rear channel for effects. The combination of these two channels with the existing left and right signals and low frequency information derived via filters or an electronic crossover gave home theater and musical presentations a realism never before possible. Dolby Digital takes surround sound to a new and even higher level. The use of digital recording techniques enables all surround channels to be full range, where the surround channel in older matrix surround systems is frequency limited. Dolby Digital also delivers six separate, discrete channels, including highly defined left and right surround channels. With two rear channels instead of the single, mono channel of Dolby ProLogic there is a greater feeling of reality and presence for surround effects such as "flyovers" of planes and spaceships. Discrete digital sound also enables complete separation between the left front, center, right front, right rear and left rear channels. The matrix system used in conventional surround recordings was often plagued with cross talk between the channels. That is now gone with Dolby Digital. 24093_ADP 303 Eng. 27/02/1998 10:34 Side 4 Introduction and Safety Information 3 WHAT IS 5.1 CHANNEL AUDIO? So far we have mentioned five channels, yet Dolby Digital is a six channel system. You may have also heard this system referred to as "5.1" channel audio. Where, you may ask, is the sixth channel, and what is the ".1" channel? The answer is simple. The sixth channel is a special low frequency effects channel, or "LFE". This is the bass channel that sends the thunder of explosions and other effects to your subwoofer. It is separate from the other five channels, brining the total channel count to six. This is true even though the "sixth" channel is non-directional, as opposed to the highly directional nature of the other signals. The reason for the ".1" designation is that the LFE channel is bandwidth limited. By definition, the LFE channel has a restricted bandwidth, while the others are full range. Thus, the system's inventors decided that although they could call Dolby Digital a six channel system, since there are six separate channels, it is more properly five "full" channels plus one separate, but limited channel. In this case, "5.1" equals six!

Depending on your application, they will either be connected to the "6 Channel Direct" inputs of products such as the AVR80 or directly to external power amplifiers . § Front SPK Switch This switch determines if low frequency signals are sent to the front left/right speakers. The factory default "Small" sends them to the subwoofer output only, while "Large" sends a full range signal to the front left/right speakers. ¶ Surr SPK Switch This switch determines if low frequency signals are sent to the surround speakers. The factory default, "Small," sends them to the subwoofer output only, while "Large" sends a full range signal to the surround speakers. Select "none" if you will not use surround speakers and to route surround audio to the front left/right speakers. · Center SPK Switch This switch determines if low frequency signals are sent to the center speaker. The factory default , "Small," sends them to the subwoofer output only, while "Large" send a full range signal to the center speaker. Select "none" if you will not use a center speaker and to route center channel audio to the front left/right speakers. IMPORTANT NOTE: These input jacks are for AC-3 digital signals only. Do not connect standard audio outputs or the PCM digital output of an LV or CD player to these AC-3 Input Jacks. ¢ 6 Channel Input Jacks When the ADP303 is used with an external preamplifier, an outboard surround processor or any AV receiver with PREAMP-OUT/MAININPUT jacks, connect these jacks to the outputs of the preamp or processor. 24093_ADP 303 Eng. 27/02/1998 10:34 Side 7 Installation & Setup 6 INSTALLATION The ADP303 delivers optimal performance when it is used with the Harman Kardon AVR80 or AVI250 although it is also compatible with many other home theater system configurations. Please follow the instructions in this section that describe the equipment and speaker choices that most closely resemble that of your own system. Depending on the equipment in use, some of the switches and settings may require adjustment, while in other cases they may be left in their factory preset positions. Depending on the specific equipment in your home theater setup, the ADP303 can be connected in one of three configuration options: · Direct connection to A/V products such as the Harman Kardon AVR80 or AVI250 that feature a SIX CHANNEL DIRECT INPUT. · Connection between an existing A/V surround processor/pre-amp and your power amplifier(s) and subwoofer (for owners of separates-based home theater systems). · Connection to the PRE-OUT/MAIN-IN jacks on the rear panel of your A/V receiver, provided that it is equipped with 5 pre-out/main-in jack pairs and a subwoofer output jack. Rear channel speakers need not be identical to the front channel speakers, but they should be of high quality. One of the benefits of Dolby Digital AC-3 is that the surround channels are full range, while they were frequency limited in earlier ProLogic type systems. Bass effects are also an important part of home theater. For optimal enjoyment a subwoofer should be used as it is optimized for low frequency reproduction. If you have large full range front speakers, however, they may be used in place of a subwoofer with proper setting of the rear panel switches. For the best advice on speaker selection consult your Harman Kardon dealer. When you have the information on your speakers, set the four switches as follows: 1) Front Speaker Mode This switch determines the frequency range of the front left/right speakers. Select Large or Small depending on the type of speaker you will be using. The factory default setting is "Small". Large: Set the switch to this position if you are using full range speakers that are capable of reproducing sounds below 100 Hz. In this position, the output to the front left/right output jacks is full range. This switch position should also be used if you are using a packaged speaker system where the first input feed is to the subwoofer. Although subwoofer/satellite systems normally use the "small" setting, some systems contain a crossover within the subwoofer, and send filtered sounds to small speakers. Consult your dealer or the speaker system's owner's manual if you are uncertain if this is an appropriate setting. Small: Set the switch to this position if you have small, frequency limited satellite type speakers that do not reproduce sounds below 100 Hz, and whenever a subwoofer is used. Use this setting if you have a subwoofer satellite system where there are separate feeds to your subwoofer and the small satellite speakers (but then an extra subwoofer is neccessary for the LFE channel). When the Subwoofer Mode Switch ª is in the "ON" position, front Low Frequency Effects (LFE) audio will be routed to the subwoofer. 2) Surround Speaker Mode This switch determines the frequency range of the rear surround speakers. Select Large, None or Small depending on the type of speakers you will be using. The factory default setting is "Small". SPEAKER MODE SETTINGS Since the ADP303 may be used with a wide variety of speaker types, it is important that you adjust the rear panel speaker mode switches before use. Setting these switches will tell the ADP303 what type of speakers you are using so that the audio outputs will be directed to the proper speaker. In general, a "Large" speaker is defined as a traditional full range speaker that includes a woofer or some prepackaged "satellite/subwoofer" systems and is capable of reproducing sounds below 100 Hz. For the purposes of this product, a "Small" speaker is one that is not capable of delivering sounds significantly below 100 Hz. (Most "satellite" type speakers fall into this category.) Before setting the switches make note of the type of front, center and rear speakers that will be used. For further clarification of your speakers' type consult the speaker owner's manual and look on the "specifications" page to find the frequency range. SPEAKER SELECTION The home theater system you already have installed should work with the ADP303 provided that there are left, center and right front speakers, left and right rear/surround speakers and a subwoofer. For best results we recommend that the front speakers be of the same type, with identical or similar driver units. This will deliver smooth pans across the front sound stage as the action moves from side to side. 24093_ADP 303 Eng. 27/02/1998 10:34 Side 8 Installation & Setup 7 Large: Set the switch to this position when using traditional full range loudspeakers that are capable of handling sounds below 100 Hz. In this position, the output to the surround output jacks is full range. None: Set the switch to this position when no surround speakers are connected. In this position the full range surround audio that would otherwise be routed to the surround channels will be mixed in with the FRONT LEFT and FRONT RIGHT audio. Small: Set the switch to this position when using smaller bookshelf or "satellite" speakers that have limited low frequency range and are unable to reproduce sounds below 100 Hz. When the switch is in the "Small" position all sounds below 100 Hz will be routed to the Subwoofer output jack. When the Subwoofer Speaker Mode switch ª is in the "ON" position, LFE surround audio will be routed to the subwoofer. When the Subwoofer Speaker Mode Switch ª is in the "OFF" position, LFE surround audio will be routed to the front left/right speakers. 3) Center Speakers Mode This switch determines the frequency range for the center channel speaker. Select Large, None or Small depending on the type of center channel speaker installed. The factory default setting is "Small". Large: Set the switch to this position when using traditional full range loudspeakers that are capable of handling sounds below 100 Hz. None: Set the switch to this position when a center channel speaker is not connected. Full range audio signals that would otherwise be routed to the center channel will be mixed in with the FRONT LEFT and FRONT RIGHT audio. Small: Set the switch to this position when using a smaller bookshelf or "satellite" center speaker that has limited low frequency range and is unable to reproduce sounds below 100 Hz. When the switch is in the "Small" position, LFE Center audio will be routed to the Subwoofer output, provided that the Subwoofer Speaker Mode Switch ª is in the "ON" position. Otherwise it's routed to the front speakers. 4) Subwoofer Mode Set this switch to determine the routing of low frequency sounds for all channels. The factory default setting is "ON", to indicate that a subwoofer is present. On: Select this position if the ADP303 is connected to an amplifier or Receiver equipped with a Subwoofer INPUT terminal, or if it is directly connected to a powered subwoofer. Off: Select this position if a Subwoofer will not be used. In this position the low frequency sounds (below 100 Hz) will be routed to the FRONT LEFT, RIGHT and/or CENTER terminals, depending on the setting of the speaker switches for those channels. 5) System Reset Once you have completed any changes to the Speaker Selection Switches turn the ADP303 off, and then on again to enter the settings into the unit's memory for future use. 1. Using the remote control or front panel controls appropriate to your receiver, processor or pre-amp, make note of the delay time setting you use for normal surround listening. 2. Press the front panel DELAY button until the delay time indicator illuminates to show a setting that is closest to that used with your conventional surround system. SYSTEM CONNECTIONS The ADP303 may be used in one of three operating modes, depending on the other equipment in your system. Before proceeding to the final adjustments, check to make certain that the ADP303 is connected to the components in your system based on one of the three options shown on the following pages. Note that proper system calibration and operation are dependent on making the right connections and use of the controls as outlined on each page. If you will be using the ADP303 in conjunction with an AVR80, AVI250 or other AV receiver equipped with direct inputs for a "6 Channel Direct" connection via RCA jacks, use the system configuration shown on page 8. If you will be using the ADP303 in conjunction with an external preamp or surround sound processor, use the system configuration shown on page 9. If you will be using the ADP303 in conjunction with an AV receiver equipped with "pre-out/main-in" jacks for all five audio channels, use the system configuration shown on page 10. DELAY TIME ADJUSTMENT Delay time adjustment enables you to adjust the timing between signals at the front and rear channels. Since the use of the ADP303 may bypass the delay settings in your receiver or preamp it is important to establish a proper delay setting for use in 6 channel operation. 24093_ADP 303 Eng. 27/02/1998 10:34 Side 9 Installation & Setup 8 INSTALLATION & CALIBRATION WITH A PRODUCT EQUIPPED FOR 6 CHANNEL DIRECT INPUT LV Player AC-3 RF Output Line Out 1 2 L R PCM Out AC-3 Data DVD 1 3 6 2 4 ADP303 LARGE SMALL LARGE NON SMALL LARGE NON SMALL ON OFF AC OUTLET FRONT SPK.
