It monitors and controls all the audio signals; it generates all the home cinema signals and sends them on to the outputs. A further task, which the 5.1 Decoder Module handles is the connection of digital sources. In this case, you can either feed the digital signals in using an optical fibre or coax cable. If the 5.1 Decoder Module has an additional DLC Module*, there is also a coax output available to control all REVOX digital speakers. You can use all normal audio formats such as Dolby Surround, Dolby Pro Logic II, Dolby Digital, DTS or MPEG with the 5.1 Decoder Module, naturally in high resolution 24 bit as well. These signals are also made available to external devices through 6 cinch sockets. The 5.1 Decoder Module handles the conversion of the symmetrical analogue signals in ultra-linear stereo operation. From here, it also goes through gold-coated silver contact relays to the output stages. Important The 5.1 Decoder module plays a very significant role for the whole system. Since it represents the Audio Control Centre, the system will not operate without the decoder module. * The DLC Module is not supplied as standard. 2 5.1 Decoder Module II Re:source Installation The 5.1 Decoder plug-in card has the most modern technology on it and should be handled with care. Before you start to install the card, the M51 must be switched off and the power plug must be removed from the power socket. Slot 7 is reserved for the Decoder module, right next to the speaker connections. No other module should be plugged in to this slot because this provides the shortest possible signal route to the outputs. Loosen the two screws with the TORX screwdriver supplied and remove the slot blanking plate. Before removing the Decoder module from its packaging, make sure that you are not charged with any static electricity. This could cause a damaging power discharge when you touch the module. To be on the safe side, you should discharge any static from yourself by touching an earthed metal object such as a radiator. Remove the decoder module from its packaging and insert it into the slot position, using the two tracks within the M51 to guide it into position. The lettering on the card must be at the top. Just before the card is fully inserted, you will feel a certain mechanical resistance as the card meets the M51 contact strip. Push the card fully home by pushing in the area where the 2 screw holes are located and fix it in place with the two screws. All further steps needed to integrate the new module into the M51 will be carried out automatically next time the unit is switched on. 3 5.1 Decoder Module II Re:source 5.1 Decoder connections Line outputs The 5.1 Decoder offers 6 line outputs where audio signals are available in 5.1 format. The following is an overview of the individual signals: REVOX DIGITAL OUT DIGITAL IN 2 OUTPUT L Line output for the left-hand front channel OUTPUT R Line output for the righthand front channel SUB Line output for the active subwoofer CENTER Line output for the centre channel SURROUND L Line output for the rear lefthand surround channel SURROUND R Line output for the rear right hand surround channel 1 OUT L PUTS 3 R SUB CEN TER L SURROUND R 5.1 Decoder 1.551.084.01 4 5.1 Decoder Module II Re:source Digital inputs These line outputs are used to supply external outputs. In the same way, active speakers can be connected. In Home cinema operation, the active subwoofer is principally controlled by the SUB output. The level of the 6 line outputs is controlled synchronously to the total volume. The 5.1 Decoder Module can play back digital sources such as a CD, MD or DAT player using the two digital inputs DIGITAL IN 1-2. You should connect the external devices to the 5.1 Decoder Module using either a Cinch cable (Digital 1 input / Softkey Coaxial) or with a fibre-optic cable with a TOSLink plug (Digital 2 input/ Softkey Optical). Active loudspeakers are speakers with integrated outputs which don't need any amplifier. The external digital sources are activated with the two softkeys in the Source menu. The line outputs are not muted during headphone operation. The externally connected digital sources are not available at the REC OUT output. They also can't be used in neighbouring rooms in Multiroom operation. 5 5.1 Decoder Module II Re:source Edit source name The 5.1 Decoder Module offers you the option to select your own name for the inputs. In this way, you no longer have to remember which external device you have connected to which input. You can label it accordingly. Select the digital source in the SOURCE menu whose name you want to change. You can choose between: Coaxial (1) and Optical (2) You call this function by pressing the Setup button for approx. 2 seconds and then pressing the Source softkey. The following display appears: Edit function You will move to the following menu display by pressing the Edit Name softkey. The following Edit functions are available: The softkey Cursor moves the [ ] cursor to the left. The softkey Cursor moves the [ ] cursor to the right. The softkey Delete deletes the cursor at the current [ ] cursor position. The softkey Insert inserts a character to the left of the [ ] cursor. The softkey Store saves the currently displayed name and returns you to the source menu. The softkey Cancel returns you to the source menu without saving any modifications made. 6 5.1 Decoder Module II Re:source Digital output* As opposed to the analogue music signal, the digital signal can carry more music channels in one cable. This is why only one cable is necessary per device for stereo or multichannel reproduction with the DIGITAL IN inputs. The coaxial digital output DIGITAL OUT is activated by the external DLC module. This DLC module is plugged onto the 5.1 Decoder Module board and is naturally available for use the next time you power on. Further details are to be found in the Speaker Configuration chapter. DLC = Digital Loudspeaker Controller * The DLC Module is not supplied as standard. 7 5.1 Decoder Module II Re:source 5.1 Decoder menu As the 5.1 Decoder module is the central unit for the processing of audio signals, this module has been assigned its own function key, namely the large key labelled as Amplifier on the front of the M51. Room sound programs The Amplifier button brings you directly into the 5.1 Decoder Main Menu. Here, you can choose between 6 Surround sounds and an ultra-lineal stereo playback: Movie Music Matrix Spatial X-Stereo Stereo The five large buttons on the front of the M51 are shown as Setup Source Amplifier Power Disc in the following chapters. The individual programmes can be selected by pressing the corresponding softkey and each programme can be set individually for each source. The inner part of the display shows a graphic of up to 5 speakers, including seating positions. The speakers which are activated by the individual programs are shown dark; the deactivated speakers are shown light. 8 5.1 Decoder Module II Re:source Sound field description Pro Logic II is a further development of Dolby Pro Logic and was developed especially for the surround-sound playback of pure stereo sources, alongside the other well-known decoding of Pro Logic sound material (mainly films). With Pro Logic II, this part handles the Music sound field, with the freely definable parameters Center Width, Dimension and Panorama. Through this, you get a realistic, enveloping sound, which you would expect from 1 5.1 Channel System. It greatly enriches the usual stereo sound that you get from the Dolby Digital multi-channel system. When you play a DVD, whether using the M51's internal drive or an external device over DIGITAL IN, the 5.1 audio format that the DVD requires is automatically selected. These are: Dolby Digital, DTS, MPEG In this case, all other surround sound programmes are blocked. Movie The Movie mode has been optimised for use with films or programmes with a sound track in Dolby Surround. It is also suitable for video games. Movie mode has all the important properties of Pro Logic, while the Stereo Surround outputs, which cover the whole frequency range, give you a sound experience that much more closely resembles the quality of Dolby Digital. Surround With this setting, the 5.1 Decoder always adapts itself to the current audio format of the selected source. This setting is recommended for use with Pro Logic quality television films, which are being shown in your living room with the original studio mix. 9 5.1 Decoder Module II Re:source Music With pure stereo music recordings, the Music mode delivers a new level of live atmosphere, which satisfies the most discerning listener. You can set up every conceivable combination of settings using the Center Width, Dimension and Panorama parameters. The choice of parameters is made through the second Menu page of Music. Center Width This parameter allows you to define the centre settings, allowing you to choose to hear the centre range just from the Center speaker, to hear it as a "phantom centre" using the right and lefthand speakers or to setup a combination of all three speakers. Depending on the requirements of your living room, you can choose, for instance, to have a partial mixture of the three front speakers or a wider or more compact sound picture. Dimension This parameter allows you to position the sound field more to the back or to the front. This enables you to get a better balance between the speakers with different recordings. Panorama mode This mode widens the output from the front speakers. In combination with the surround boxes, this gives you a fascinating and enveloping effect with those sounds that are located at the edges of the sound picture. 10 5.1 Decoder Module II Re:source Matrix This parameter primarily increases the surround effect for programmes sources recorded in stereo sound, by using an elaborate Dolby Matrix decoder. Spatial This is a living sound picture, which was developed in the REVOX sound studios. It emulates a small hall where you might expect to hear some live jazz or chamber music. For this reason, Spatial is particularly well suited for listening to this or similar music types. X-Stereo With this stereo sound, the stereo signal is also sent to the rear surround speakers but as a mirror image. This means that you have stereo reproduction between each pair of speaker. With a square layout, this can give a fantastic feeling of space. Stereo Additionally, it is possible to listen to music in pure stereo with out the influence of any room sound program. In the lower display field this is indicated with . In this case, the audio cables are connected directly to the outputs on an ultra linear amplifier path. If, however, you want to modify the treble and bass settings in stereo mode, this will take you out of the ultra linear path. Playback is then done through a DSP as shown by the display field at the bottom of the screen. All surround speakers are deactivated in this function and are therefore shown as light symbols on the display. 11 5.1 Decoder Module II Re:source Amplifier sub-menu The Sound fields have different sub-menus to fine-tune your desired sound settings. You will find an overview of which sub-menus are available for which sound fields at the end of the description of the individual sub-menus. Level setting The sub-menu shown below suggests level settings for the surround speakers, including Center and Subwoofer: The speakers can be adjusted to the correct volume ratio to the main speakers using the softkeys. This function allows you to make a temporary adjustment to the Center and Surround volumes. The settings are automatically reset as soon as another source is selected or the M51 is switched off. The setting for the Subwoofer, on the other hand is saved until the next modification of the subwoofer level or until a complete reset using the Reset k ...
