This is where you can change the surround receiver settings which are only occasionally required in normal daily listening: perhaps to allow for temporary changes in the listening room, or to compensate for unusual characteristics of a special listening source (see 'Main Menu').
Remote control of the Surround Decoder General information In the drawings some of the buttons are filled in ( ); these are the ones which are required for remote control of the decoder. The other buttons have no effect on this unit. The digital surround decoder can be controlled using the F6, F12 remote control handset, or the F1 system remote control unit. If you are using the F1 handset, it must first be switched to Hi-Fi mode.
F1 F12 F6 Switch the handset to Hi-Fi mode.
Menu control system To keep the control panel of the digital surround decoder as compact and uncluttered as possible, the panel does not include dedicated buttons for controlling the decoder functions of tone and level adjustment directly; instead a menu control system ('Main Menu') is used. The following table shows how the menu control system is operated using the remote control buttons, or the buttons on the decoder’s front panel.
Main Menu The 'Main Menu' is designed for adjustments to the decoder which are only occasionally required for daily listening; perhaps to allow for temporary changes in the listening room, or to compensate for unique characteristics of a special listening source. To open the 'Main Menu' press the remote control button or briefly, or the button on the decoder’s front panel.
Sound fields: 2-Channel Mode / 5.1 PL IIx Mode: Disco This sound field is particularly suitable for providing an even spread of sound over a dance area. The sound signal is reproduced with equal power by the main and surround loudspeakers, without echo or delay. The strongly concentrated sound reproduction generates an immediate, energy-charged atmosphere which is a great choice for any party. This menu point enables you to select the decoder for 2channel input signals (e. g. from stereo sources).
Balance left/right and front/surround: Dynamic range: These two menu points allow you to set a temporary change in the balance between the left/right and front/rear loudspeakers, in order to compensate for a temporary listening position which is less than perfect. You can alter the balance in 1 dB increments, and the current value is displayed in the following form: The dynamic range is the difference in volume between the quietest and loudest passages of a recording.
System Configuration This procedure only needs to be carried out when you are installing the system, or when you are adding or replacing individual components of the system. The following diagram shows the menu structure. In the 'Configuration' you can adjust the settings for all the audio and video components of your surround system so that they match each other perfectly, and at the same time set them to suit the acoustic characteristics of your listening room.
Configuration You can call up the 'Configuration' menu by pressing the remote control button or , or the button on the front panel of the decoder; in either case hold the button pressed in for about two seconds. Display brightness: Loudspeaker: The brightness of the screen can be set to suit your personal preference. Three brightness levels are available: The 'Loudspeaker Menu' provides the means to balance the output signals to the loudspeakers in your surround system.
Speaker Setup The three last menu points enable you to adjust the loud-speakers accurately to suit the acoustic and spatial characteristics of your listening room. In the 'Loudspeaker Menu' you can branch off to the menus for setting the loudspeaker size, loudspeaker position, loudspeaker balance and the individual tone settings for each separate loudspeaker.
Speaker size menu To avoid the loss of any sound information in systems where not all the loudspeakers (centre, rear and subwoofer) are present, the missing components must be marked as none in the 'Speaker size menu'. In the 'Speaker size menu' you initially adjust the output signals to suit the existing loudspeaker system. The corresponding sound signal is then distributed over the channels which are present (Downmix). Select menu point Change value Speaker size Main speaker Center speaker Surr.
Back speaker: 5.1 Surnd LS Setting the size and bass capability of the back loudspeakers. The following settings are possible in each case for one (6.1 mode) or two (7.1 mode) rear loudspeakers: As described under 'Surround systems - explanatory notes', the recommended settings for 5.1 loudspeaker sets differ from those for 6.1 / 7.1 speaker sets. To achieve the correct surround effect the surround loudspeakers are located behind the listener for the 5.
Subwoofer: Satellite high pass: In this menu point you set whether a subwoofer is present in your loudspeaker system. Select one of the following settings: Here the lower transition frequency for satellite speakers can be selected. The bass range below the frequency set here (for all loudspeakers whose size is set as 'Satellite') is mixed by the bass manager onto other suitable loudspeakers and the sub-woofer. Bass-manager recommended setting woofer / satellite systems.
Speaker Position Menu This enables the decoder to compensate for timing discrepancies due to differences in speaker location. In the 'Speaker Position Menu' you can enter the distance from the listening position (in 0.3 m increments) for each loudspeaker separately. Recommended loudspeaker arrangement 5.1 Loudspeaker set 7.
Speaker Balance Menu To ensure that the decoder supplies a balanced sound image, the system allows you to adjust the volume of the individual channels to provide a harmoniously balanced arrangement. The purpose of the 'Speaker Balance Menu' is to adjust the level of all the channels. Select menu point Change value -10(dB) . . . 00(dB) . . . +10(dB) -10(dB) . . . 00(dB) . . .
Tone adjust Menu The decoder features an active tone control system (+/6dB) whose purpose is to compensate for the unwanted influence on playback quality of your listening room, or of imperfect loudspeaker positions. The treble / bass balance can be adjusted separately for all the output channels, and can therefore compensate for problems caused by the location of individual speakers.
Auto Setup provides the Auto Setup system as an aid to setting up a surround system correctly. If you follow the steps described below, the DD 1535 R will carry out an automatic calibration of your loudspeakers with the help of the calibration microphone supplied with the set. Under normal listening room conditions this process reliably provides optimum results. The first step is to connect the calibration microphone to the socket marked 'MIC' on the front panel.
Video Inputs menu Every AV source device is connected to one of the AV inputs of the DD 1535 R by means of a Video or S-Video cable, in order to supply picture data to the DD 1535 R. In the 'Video Inputs menu' you determine for each AV input whether the source device connected to it is to operate in normal Video or S-Video mode. Notes: If your device features S-Video outputs, we recommend that you use S-Video mode, as this provides better picture quality.
YUV Inputs menu Some source devices provide picture signals using the high-quality Component Video norm (YUV, YPbPr or YCbCr). If your video monitor features a corresponding Component input, we recommend that you connect all YUVcapable sources using YUV cables in addition *) to the standard Video or S-Video connections. In the YUV Inputs menu you determine which source is connected to which YUV input.
Audio inputs Menu Some source devices also generate a digital output signal, others an analogue multi-channel signal (MCH). Alternative input sockets of the DD 1535 R can be assigned to these source devices; these inputs are suitable for digital signals (co-axial or optical) and multichannel signals. Up to eight AV source devices (with picture and sound signal) can be connected to your surround receiver.
Special Functions menu In the Special Functions menu you can set the following points: TRIGGER 2 / TRIGGER 3 Audio delay for all sources: The back panel of the DD 1535 R features control outputs for automation functions. For example, you can use them to control a motorised screen, so that it extends automatically when you select a video source; alter-natively the light could be dimmed automatically when you select video operations.

Optimising the system Loudspeaker and signal leads Physical insulation The loudspeaker and signal leads used affect the playback quality of the entire system to an extent which should not be underestimated. therefore recommends the use of high- quality leads and connecting plugs. Tone quality is influenced to a considerable extent by the type of surface and underlying support on which sophisticated HiFi instruments are placed. As far as possible, the surface should be strong, stable, rigid and level.
Surround sound - explanatory notes General information: Types of reproduction The following section is not concerned directly with the operation of your DD 1535 R decoder, but is rather intended to explain some of the terms which arise in connection with surround systems. It is intended to help you understand and exploit the facilities and capabilities of your DD 1535 R to the full.
The surround system This interface is the key to integrating the decoder elegantly into the overall system. At the same time the decoder has absolutely no effect on normal stereo signals, since it is completely removed from the signal path during normal stereo operations. Multi-channel reproduction based on surround technology does indeed open up new worlds of experience, but the technical implementation of a multichannel surround system does involve a number of potential pitfalls.
Dolby Pro Logic IIx Surround Dolby Digital is a digital multi-channel surround system which was developed specifically for spatial sound reproduction in connection with cinema films. The process utilises five separate sound channels: three front channels (left, centre, right) and two surround channels. A sixth independent bass effect channel is also present, catering for low frequency effects (LFE). That is why such systems are said to offer 5.1 channels.
STEREO / MONO mode: dts Digital Surround Stereo The “dts” multi-channel film sound system was originally developed to replace analogue film soundtracks, using digital recordings consisting of six discrete channels. This system has now been further developed to provide spatial sound reproduction in the home situation. Note: A multi-channel signal is converted into a stereo signal (downmix), and reproduced via the main left and right loudspeakers. The six channels (5.
Your DD 1535 R can generate the following sound fields: Sound field simulation The surround processes already described require programme material which is encoded using the appropriate system, but the DD 1535 R also offers a facility to enhance the spatial effect available with conventional unencoded stereo recordings (CD, MC, FM radio etc.). Disco These sound field simulations are based on an accurate analysis of the room acoustics of a number of popular room and hall types.
Dolby Headphone Dolby Headphone is a system which provides a form of spatial sound image even with conventional stereo headphones. Dolby Headphone is a process by which the music signal is processed to simulate the characteristics of music reproduction in a normal room; the result is that an approximation of the usual listening experience is possible even using headphones. Method of working: Dolby Headphone goes even further than this, and incorporates the rear channels which are present in 5.1 / 7.
Loudspeaker configurations for the DD 1535 R To ensure that the SR 1535 R is able to distribute the information in all recordings correctly to your individual loudspeaker combination, it is important that you enter the correct settings in the Loudspeaker Configuration menu when installing your system, i. e. which loudspeakers are present and connected, what size they are, and how far they are located from the listening position.
Auxiliary YUV sockets If your video monitor features a YUV input, you should connect the monitor and all YUV-capable source devices using YUV cables in addition to the Video or S-Video wiring. You can then switch your monitor to YUV mode when using these sources, and in this way obtain the absolute best possible picture quality when watching a film.
Trouble-shooting Many problems have a simple cause and a correspondingly simple solution. The following section describes a few difficulties you may encounter, and the measures you need to take to cure them. If you find it impossible to solve a problem with the help of these notes please disconnect the unit from the mains and ask your authorised specialist dealer for advice. Service Menu The operation of the service menu is similar to the operation of the setup menu (see chapter 'Menu control system').
