Welcome.

We are delighted that you have decided to purchase a  product. With the addition of the digital surround decoder to your  Hi-Fi system you are expanding it to embrace a completely new dimension: Audio-Vision.

With the digital surround decoder you can play Dolby Surround, Dolby Digital programmes, video films and DVDs and experience a genuine “live” atmosphere, complete with exciting sound effects. The digital surround decoder is also capable of generating artificial sound fields, which enhance the apparent reality of non-encoded programme material. For example, if you are watching a sports programme, you can allow yourself to be transported into the stadium, or listen to a jazz concert in an authentic simulation of the atmosphere of a typical jazz club.

Of course, it is essential that all these new facilities should have no detrimental effect on the excellent sound qualities of your Hi-Fi system, and the design of your new machine has been carefully thought-through from start to finish to ensure that this is the case.

As you would expect, the digital surround decoder features five high-quality output stages of discrete construction, offering outstanding sound characteristics and generous reserves of power, and they can cope with impedance-critical loudspeakers and complex surround effects covering a very wide dynamic range without turning a hair. The unit includes a high-precision digital signal processor which is responsible for precise decoding of the surround material as well as generating the sound fields.

Naturally, we have remained faithful to our basic design and manufacturing principles in developing the digital surround decoder. This design philosophy includes an insistence on durability and reliability, the avoidance of materials which are environmentally harmful, the use of metals instead of plastics, and the exclusive exploitation of high-quality, thoroughly tested materials. To ensure consistently high product quality we subject everything we make to a comprehensive monitoring process, terminating in a fully automatic computer-controlled final quality check and acceptance procedure.

Optional accessories for this unit include high-quality cables and connectors, together with a range of specialised furniture designed to match the design of our equipment.

We have gathered some basic information on the subject of surround sound and video connections in the sections 'Surround systems - explanatory notes', 'Loudspeaker configuration for the DD 1535 R' and

Picture norms, connecting AV devices to the DD 1535 R'. If you are not familiar with these subjects,

please read these sections first, as they will help you understand how to install and operate the equipment.

We are grateful to you for placing your faith in us, and hope that you will enjoy many hours of pleasure with your  digital surround decoder.

Note:

The DD 1535 R is designed specifically for use with a  R-series stereo pre-amplifier, amplifier or receiver with an R

VCR recordings with the DD 1535 R

The overall design of the SR 1535 R enables you to select an recording source regardless of the viewing / listening source currently selected.

This facility make it possible to record one AV source device (e. g. SAT receiver), while you simultaneously view and listen to another AV source device (e. g. DVD player).

If you wish to make a timer-controlled VCR recording, you must first select the appropriate recording source (e. g. SAT receiver).

At the time the recording is to take place, the decoder must not be completely switched off (i. e. it must be switched on or in stand-by mode).

In stand-by mode the decoder confirms its actions by displaying the selected recording source on its screen in dimmed form: 'REC' and source name.

Automatic power-off:

Normally the decoder switches itself off in parallel with the master device. If the system is switched to stereo mode, the screen shows:

'PREAMP

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.

Listening mode:

At this menu point you can select the decoder’s playback mode or sound field which you wish to use. The decoder

'remembers' your chosen setting for each input (DVD, CD, Tuner, ...), and selects it every time you switch to that input.

Surnd EX/ES (Dolby Digital EX / DTS ES decoder

version). The DTS ES and Dolby Digital Surround EX digital multi-channel signals are detected and decoded. The surround channels are reproduced by the surround loudspeakers and one or two rear loudspeakers (6.1 /

Not all signal sources (DVDs, CDs etc.) which are encoded with Dolby Digital or dts Digital Surround always contain information on all channels. Even if the screen indicates that a particular channel is present, this does not necessarily mean that the loudspeaker in question will always produce sound.

In every playback mode signals may be present on the subwoofer channel; this depends on the loudspeaker arrangement you have selected in the 'Speaker Setup'.

Surnd 5.1 (Dolby Digital EX / DTS ES decoder version) The DTS and Dolby Digital digital multi-channel signals are automatically detected and decoded. The surround

channels are reproduced by two surround loudspeakers (5.1 mode).

Stereo Even if a multi-channel signal is detected, the decoder converts it into a stereo signal, i. e. all channel information is mixed down and sent to the main left and right loudspeakers.

Mono All channels are mixed down onto the center loudspeaker channel.

Mono I Mode for two-channel TV sound Generally Channel I transmits the synchronised sound. The signal from Channel I is reproduced via the Centre loudspeaker *); Channel II (original sound) is suppressed.

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.

Hall Reverberant concert hall with sound reflections from all directions. Ideal for playing back recordings of large orchestras, or simulating the live atmosphere of a large rock concert hall - an excellent choice for very dynamic rock music.

Theatre This program combines clear voice reproduction with the full sound of an orchestra, but without exaggerated reverberation. The spatial sound towards the rear is slightly limited, in the interests of better orientation.

Stadium This sound image concentrates the “presence” in the front area, helping to localise commentators and dialogues on the screen. Sound from the rear is designed to give the impression of being amongst the spectators in the stadium. This sound field is also suitable for TV shows and music programmes.

Club The characteristic atmosphere of a cellar jazz club, with a pattern of reflections dominated by large floor and wall surfaces. Also good for simulating small halls.

Church Simulation of the acoustic conditions in a large church, with long reverberation times. This sound field is an excellent choice for sacred organ music.

This menu point enables you to select the decoder for 2channel input signals (e. g. from stereo sources). The Dolby Pro Logic II(x) process is available in three different configurations (see also 'Surround systems -

explanatory notes').

If the MCH-IN input is assigned to the active source. In this case the sound signal of the Multi-channel input is used.

Note:

The selection ‚DD EX‘ is normally not necessary. In contrast to Dolby Digital EX the Dolby Pro Logic IIx creates two back-channels instead of one. Only if the back-channels of Dolby Digital EX coded material is reproduced diffusely or nervously, this option may be helpful.

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:

10L (left) . . . . . . . . 10R (right)

10R (surround) . . . 10F (front)

Center (neutral position)

Note:

It is important to start by setting the correct balance for the “standard” listening position, adjusting the volume of the front, surround and center channels. This task is carried out in the 'Speaker Balance Setup'.

Tone: treble and Tone: bass:

These two menu points allow you to set a temporary change in the treble and bass settings in order to compensate for tonal differences in the recorded material. The setting affects all channels, and the range of adjustment is +/- 6dB in 1 dB increments. The current value is displayed on the screen; 00 dB means 'Linear setting'.

The dynamic range is the difference in volume between the quietest and loudest passages of a recording. The original sound track of a film usually features a very wide dynamic range, and the decoder is capable of reproducing the full range.

Unfortunately not every listening room can cope with the full dynamic range which the decoder is capable of reproducing. You also have to consider your neighbours, especially in the late evening.

To cope with these problems it is possible to reduce the dynamic range of Dolby Digital encoded sound material in three stages. The result is that quiet passages (e. g. low-level conversations) are reproduced slightly louder when the volume is set low, whereas loud passages (e. g. gigantic explosions) are slightly reduced in volume.

The following dynamic ranges are available:

standard highly compressed dynamic range, e. g.

for playing at night-time.

full exploits the full dynamic range which the

sound source makes available.

Note:

It is important to start by establishing the correct tone settings for your room, to allow for imperfect loudspeaker positioning or room influences. This task is carried out in the 'Tone Control Menu'.

Subwoofer level:

If you switch on the subwoofer in the 'Speaker Setup', in this menu point you can adjust its level within the range 10 (dB) to +10 (dB) in order to match its volume to the acoustic conditions in your listening room, and to match the volume of the other channels.

If the subwoofer is switched off in the 'Speaker Setup', this menu point in the 'Main Menu' shows off . You cannot adjust the subwoofer level in this situation.

Note:

It is important to start by setting the correct balance between the other channels (front, rear and center). This task is carried out in the 'Speaker Balance Setup'.

Note:

Any adjustment to the dynamic range only affects Dolby Digital encoded sound sources.

Sound Delay:

Some video monitors - especially 100 Hz types, plasma monitors and monitors with progressive scan function create a delay in picture reproduction. In such cases the result may be poor synchronisation between sound and picture. Since certain source devices employ different picture transfer processes (analogue, progressive, SDI, HDMI), the sound delay may also be due to the source device. In the menu point Sound Delay you can set a delay for sound reproduction within the range 0 … 150 ms in order to correct the synchronisation between sound and picture (“lip synchronisation”). This value can be set separately for each source device (see also the 'Special Functions' menu for a simplified method of setting the basic value).

System Configuration

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.

Overview of 'Configuration Menu'

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.

If you set brightness level 'off', the screen switches briefly to normal brightness every time you give a command, so that you can check the settings easily even from a distance. After about four seconds the screen automatically switches back to your preferred brightness level. If you change the brightness level, this also means that the new value only becomes effective after about four seconds.

Switching the on-screen main menu on and off:

If you just wish to make a temporary change to the balance or tone, it is not absolutely necessary to call up the 'Main Menu' on the television screen and superimpose it on what you are watching; in most cases the display on the decoder’s screen is quite adequate. At this menu point you can switch the TV on-screen main menu display on and off.

Video inputs:

In the 'Video inputs Menu' you can set the correct picture norm to match the picture sources connected to all the decoder’s video inputs and outputs.

YUV inputs:

Many source devices feature a high-quality Component (YUV) picture output. If you wish to use this, the source device must be assigned to the YUV input of the

DD 1535 R in the 'YUV Inputs menu'.

Audio inputs:

The ‘Sound Inputs Menu’ is used to integrate the AV sources connected to the decoder in the overall control system of an 'R'-system. This is achieved by first assigning a name to each AV source device connected to the decoder; it will then appear under this name on the decoder’s integral screen. You can then select the Audio / Video input socket(s) to which it is connected. Finally a source button on the remote control handset can be assigned to each AV source, which is then used to select it in surround mode.

On-screen language:

The on-screen menus can be displayed on the TV screen in different languages. Here you can select your language.

Speaker Setup

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:

The three last menu points enable you to adjust the loud-speakers accurately to suit the acoustic and spatial characteristics of your listening room.

Adjustments should only be made to these settings when you are installing the system, if you are adding, replacing or moving individual loudspeakers, or if the acoustic conditions in your listening room are changed (e. g. changes to the furniture, carpets, curtains etc.).

Speaker balance:

Activating this menu point leads to a menu in which you can determine the size of the loudspeakers and the sub-woofer mode. Here you can also select the transition frequency for satellite / sub-woofer mode. This ensures that all the loudspeakers are fed only the frequency range which they can actually reproduce.

You can also select at this point whether the surround channels of 5.1 input signals are only to be reproduced by the surround loudspeakers, or by the back loudspeakers, or both (see 'Speaker size menu').

Speaker position:

Activating this menu point leads to a menu in which you can determine the loudspeaker positions. Here you can enter the correct distance from each loudspeaker to the listening position. This compensates for delay discrepancies caused by differences in speaker distance from the listening position (see 'Speaker position menu').

Activating this menu point leads to a menu in which you can set the level balance between all the loudspeakers (see 'LS balance menu').

Tone controls:

Activating this menu point leads to a menu in which you can adjust the tonal balance of the loudspeakers (see

'Tone controls menu').

Auto Setup

The menu point 'Auto Setup' represents an alternative to setting up the loudspeaker parameters manually, using the 'LS Balance' menu. Calling up the Assistant initiates an automated routine for setting the correct volume, tone setting and position of the individual loudspeaker channels in your surround system.

Notes:

If no back speakers are present, the surround mode 'Surnd EX/ES' cannot be selected, and Dolby Digital Surround EX and DTS ES are reproduced as normal 5.1 sound.

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 5.1 set-up, whereas they should be positioned more to the side of the listener with the 6.1 / 7.1 arrangement. For this reason it is possible to select here whether the surround information in the 'Surnd 5.1' mode is to be reproduced by the surround speakers, the back speakers, or both.

Surnd only The surround signals are reproduced

only by the surround loudspeakers.

Back only The surround signals are reproduced

only by the back loudspeakers.

Surnd+Back The surround signals are reproduced by

both the surround and the back loudspeakers.

Note:

If only one back loudspeaker is present, the 'Back only' setting cannot be selected.

If you select the setting 'none' in the menu point 'Surround loudspeakers', the back loudspeakers are automatically switched off.

Not all combinations can be set; this is deliberate in order to avoid senseless settings.

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:

woofer / satellite systems.

If a sub-woofer is present. The signals of the bass effect channel (LFE), and all other low frequency bass signals (below the set transition frequency) which are not reproduced by the full-range loudspeakers, are passed to the sub-woofer channel. In this mode it may occur that the sub-woofer has no signal to reproduce in some surround modes or with multi-channel input signals which lack an LFE channel.

If the bass manager is in use, the low-pass filter on the sub-woofer should be switched off, as the bass manager carries out the filtering.

Permanent recommended setting for full-range

loudspeakers and sub-woofer.

If a sub-woofer is present and you wish it to operate constantly. In addition to bass management the signals of all channels are mixed together and reproduced by the subwoofer.

For constant sub-woofer operation the lowpass filter on the sub-woofer must be switched on and the transition frequency on the subwoofer set in such a way that the sub-woofer only reproduces signals below the bottom transition frequency of the main loudspeakers (generally 30 - 40 Hz).

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.

The following values (Hz) can be set:

50 60 70 80 90 100 120 150 180

none if this setting is selected, at least the main

loudspeakers must be full-range types.

If no sub-woofer is present. The signals of the bass effect channel (LFE) and all other low frequency bass signals (below the set transition frequency) are reproduced by the main loudspeakers.

Note:

Provided that you have switched on the subwoofer in the 'Speaker Setup', then you can adjust its level in the 'Main Menu' within the range -10 (dB) to +10 (dB), so that the volume of the subwoofer matches the volume of the other channels.

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.

If the calibration process is to work properly the following conditions need to be fulfilled: an unobstructed location for the calibration microphone close to your preferred listening position (e. g. on the living room table, or on the backrest of an armchair), and direct visual contact between the microphone and each loudspeaker.

The first step is to connect the calibration microphone to the socket marked 'MIC' on the front panel. Now set a normal volume for listening to the system.

To ensure that the calibration can be carried out properly, the volume must first be set correctly. To this end the DD 1535 R generates a hiss signal on the front left channel. The screen displays the currently set volume value in the 'Volume' line, followed by the button you need to press. 'VOL+' means that the volume is too low; 'VOL-' means it is too high. Only if the display shows 'OK' can the calibration process be initiated by pressing the 

 button.



The DD 1535 R now carries out the automatic calibration process. During the procedure you will hear your loudspeakers emit various test signals. During the period of the calibration procedure it is important that no loud extraneous sounds should occur, as these could falsify the results of the process.

The 'Auto Setup' screen display on your TV set provides constant information about the settings the system has determined.

The first columns show the values determined for the set level corrections (volume compensation). The following two columns list the bass and treble settings, and the final column the loudspeaker distances.

Notes:

If the calibration process was adversely affected by extraneous noises, or if for any other reason the calibration process produces implausible results, note that the procedure can be re-started at any time.

The distances determined by the Assistant are calculated on the basis of acoustic delay times. They may be slightly different from the geometric distances due to signal delays in your loudspeakers.

If the automatic calibration procedure produces incorrect results due to difficult acoustic conditions in your listening room, we suggest that you should first attempt to achieve better results by varying the microphone position and / or the volume setting.

If this also fails to produce good results, the automatic calibration process is not suitable for your conditions. In this case you should set up the loudspeakers manually using the 'Loudspeaker Menu'.

Page 25

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.

For more information on picture norms please refer to the chapter 'Picture norms, connecting AV devices to

the DD 1535 R'.

Notes:

If your device features S-Video outputs, we recommend that you use S-Video mode, as this provides better picture quality.

Page 26

YUV Inputs menu

Some source devices provide picture signals using the high-quality Component Video norm (YUV, YPbPr or YCbCr).

In the YUV Inputs menu you determine which source is connected to which YUV input.

For example, if the DVD player is connected to YUV input 1, as in 'Wiring Diagram 4', you should enter DVD in the YUV-1 line of the menu. Repeat the procedure with all your YUV sources.

If you select a source configured in this way, the DD 1535 R switches the normal video signals (Video or S-Video) of this source through to the corresponding MONITOR output. At the same time the YUV signals of the source are passed to the YUV monitor output.

You can then switch between inputs on your video monitor, in order to decide whether you prefer to watch the film in normal video quality or in YUV quality.

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.

OSD Video standard

The DD 1535 R is capable of generating its user menus (OSD = On-Screen Display) and displaying them on the video monitor connected to it via the Component Video output using the YUV or RGB video norm. Here you should enter the picture norm used by your projector.

This setting only affects the Component Video output. It has no effect on the normal Video and S-Video outputs of the DD 1535 R.

*) You cannot simply decide not to connect the Video / SVideo signals, as YUV signals cannot be recorded by video recorders.

Page 27

Audio inputs Menu

Up to eight AV source devices (with picture and sound signal) can be connected to your surround receiver.

The analogue stereo signals of the external source devices are passed to the DD 1535 R via the co-axial Cinch sockets.

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.

In such cases the assigned digital or multi-channel signal from the decoder is accepted and processed instead of the analogue stereo input signal.

The alternative inputs are assigned within the 'Inputs Menu'.

The illustration of the menu on the left lists the available alternative inputs of the DD 1535 R - the co-axial and optical digital inputs ( DIG-1, DIG-2, DIG-3, DIG-4, DIG-5, DIG-6 ) and the multi-channel input MCH-IN.

Each of these alternative inputs can be assigned to an audio or AV input.

Examples:

(see Wiring Diagram 3)

The digital sound signal of the DVD player is connected to the co-axial (Cinch) digital input DIG-3 of the DD 1535 R; for this reason the name DVD must be added to DIG-3 as a suffix - and that is the factory default setting.

(see Wiring Diagram 5)

The digital sound signal of the SETTOPBOX is connected to the optical digital input DIG-1 of the SR 1535 R; in this case the name STB must be added as a suffix to DIG-1.

MCH-IN

Note:

The Multi-channel input is only active if the MCH-IN surround mode is selected. This mode can only be selected for the source to which MCH-IN is assigned.

Page 28

Special Functions menu

In the Special Functions menu you can set the following points:

TRIGGER 2 / TRIGGER 3

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.

In this menu you can determine which conditions cause Trigger signals 2 and 3 to be generated.

Trigger signal 1 is switched automatically when the device is switched on, and cannot be configured.

If you have queries regarding the automation facilities and how they can be implemented, please ask your local  specialist dealer or an experienced electrician.

Audio delay for all sources:

The basic sound delay setting (LipSync) is crucially dependent upon the picture delay time of the display device - but it may also vary from one source device to the next. For this reason the DD 1535 R can be set to a different sound delay for each source.

To make it easier to set these values, this menu point can be used to set the delay time of the display device as the basic value for all sources. This value can then be altered individually in the Main Menu.

The operating instructions for your display device may state suitable values. If not, the following can be taken as a sensible starting point:

SAFETY NOTES

All the components we use meet the currently valid German and European safety norms and standards.

Our production areas are supervised by highly qualified expert staff, and all final production units are checked comprehensively by a fully automated, computercontrolled system to ensure uniformly high quality. W e guarantee that our products meet our own specifications to the full.

Please read right through these operating instructions carefully before you attempt to use your new surround receiver. Note in particular the information regarding setting up and operating the equipment, and the safety notes.

The unit must be set up in such a way that none of the connections can be touched directly (especially by children). Be sure to read the information in the section entitled 'Installation'.

The power supply required for this decoder is printed on the mains supply socket. The unit must never be connected to a power supply which does not meet this specification. If the unit is not to be used for a long period, disconnect it from the mains supply at the wall socket.

Mains leads must be deployed in such a way that there is no danger of damage to them (e. g. through persons treading on them or from furniture). Take particular care with plugs, distribution panels and connections at the surround receiver.

Liquid or foreign bodies must never be allowed inside the case. Protect the unit from drips and splashes of water; never place flower vases or fluid containers on the unit. Mains voltage is present inside the unit, and there is a risk of lethal electric shock. Do not exert undue force on the mains connectors.

Caution!

The mains button is not a mains isolation switch. Even when the green LED is not glowing, parts of the machine remain connected to the mains power supply. If the decoder is not to be used for a long period, we recommend that you isolate it from the mains by pulling out the mains plug at the wall socket.

This device should never be used without proper supervision. The surround receiver should be set up well out of the reach of small children. This applies to all electrical equipment.

The unit should only ever be opened by a qualified specialist technician. Repairs and fuse replacements should be entrusted to an authorised  specialist workshop.

With the exception of the connections and procedures described in these instructions, no work of any kind may be carried out on the surround receiver by unqualified persons.

If the unit is damaged, or if you suspect that it is not functioning correctly, immediately disconnect the mains plug at the wall socket, and ask an authorised  specialist workshop to check it.

The unit may be damaged by excess voltage in the power supply, the cable network or in aerial systems, as may occur during thunderstorms (lightning strikes) or due to static discharges.

Special power supply units and excess voltage protectors such as the  'Power Bar' mains distribution panel offer some degree of protection from damage to equipment due to the hazards described above.

However, if you require absolute security from damage due to excess voltage, the only solution is to disconnect the unit from the mains power supply and any aerial systems.

If you believe there is a danger of excess voltage (e. g. when an electrical storm is building up) disconnect the surround receiver from the mains and the aerial socket.

All mains power supply and aerial systems to which the unit is connected must meet the currently valid regulations, and must be installed by an approved electrical installer.

Note:

Many insurance companies offer lightning damage insurance for electrical equipment as part of their household insurance service.

Optimising the system

Loudspeaker and signal leads

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.

Our range of accessories includes a series of excellent leads and plugs possessing characteristics which have been matched to our loudspeakers and electronic components and which combine with them to give outstanding results.

If the space for the player is inconvenient or restricted, you will also find leads of non-standard lengths and special plugs (e. g. angled) among the  accessories with which almost any connection or setting-up problem can be satisfactorily resolved.

Mains leads and filters

Apart from supplying the necessary power for your video/audio equipment, the mains electricity system can also cause interference from domestic appliances, radios and computers situated elsewhere in the home.

To prevent electromagnetic interference, our range of accessories includes the specially shielded POWER FOUR mains lead, the POWER LINE mains lead with sleeve core filters and the POWER BAR multiple socket outlet with mains filters.

In many instances, the playback quality of our equipment can be further enhanced with these accessories.

Your  dealer can provide you with comprehensive, expert, non-obligatory advice on all matters associated with leads and connections. We can also supply comprehensive informative material on this subject on request.

Physical insulation

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. The player is fitted with the newly developed  insulating feet which possess internal cushioning and thus effectively insulate the player from the surface on which it stands.

Note:

The screw-type feet can be tightened or eased off if it is necessary to compensate for irregularities in the surface when levelling the player.

The player must be adjusted in such a way that it is level in all directions. All the feet must rest securely on the surface, i. e. the player must not rock.

Surround sound - explanatory notes

General information:

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.

As we all know, a normal stereo recording has two channels - left and right. When stereo material is reproduced in your listening room, the entire sound event takes place on an imaginary stage which covers the space between the two loudspeakers.

The listener is able to locate specific sound events over the width of the stage; with good recordings there is also a slight impression of depth, i. e. behind the speakers. Nevertheless, normal stereophonic reproduction always leaves the listener isolated from the event.

As a result it is impossible to recreate the excitement of a live atmosphere, as in a real concert hall, since the acoustics of the concert hall are crucially influenced by sound reflections from the side and back walls, the floor, the ceiling, and from objects inside the hall.

The reflected sound comes from any number of directions - not just from the front. If a sound event is to be reproduced with real fidelity, it therefore follows that a proportion of the sound must emanate from all directions in the room, that the “reflections” must be timed accurately, and that they must be generated at a realistic level.

Reproducing television sound via a conventional stereo system is problematic, because it is often impossible to locate dialogue on the screen itself.

A further point is that exotic sound effects have been in use in the cinema since the 1950’s, using proper multichannel sound systems. These effects are often crucial to the overall impact of a film, but they cannot be reproduced at home with a conventional stereo sound system.

Over the last few years surround technologies have been developed which make it possible to experience all these effects within the listener’s own four walls, with the result that a far greater simulation of reality is possible than with conventional stereo.

For an effective surround system we always recommend the installation of a centre loudspeaker, which is installed below or directly above the TV set. This loudspeaker helps greatly in locating particular sound events (especially dialogue) on the TV screen itself.

Types of reproduction

The DD 1535 R makes available a range of different types of reproduction: multi-channel mode, mono/stereo mode and sound fields.

The surround receiver ‘remembers’ the setting for each input, and reverts to the mode of operation which was last used for that input when you switch to it from another input.

Multi-channel mode (surround):

Mode of operation for the reproduction of multi-channel programmes (e. g. DOLBY Pro Logic II, DOLBY DIGITAL, dts, etc.)

Digital multi-channel signals are detected by the encoding methods employed, and the surround receiver automatically sets the correct loudspeaker assignment. The current reproduction mode is displayed on the front panel screen.

For analogue input signals the correct mode of operation cannot be detected automatically by the decoder. In this case the surround receiver always reverts to Dolby Pro Logic II decoding. If the signal is actually in a different form (stereo, mono - see below), then the mode must be set manually instead of surround mode.

 surround system



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. Many existing surround systems have gained a reputation for no more than moderate sound quality, especially when used in normal stereo mode.

The reason for this lies in the tiny magnitude of the sensitive analogue stereo signals. These signals are measured in the range of just a few Millivolts (thousandths of a Volt), and unwanted interference to these signals can be perceived by the human ear even when a thousand times smaller than that. Conventional surround amplifiers feature a single case in which digital signals and high-frequency video signals live in the same space as the sensitive analogue signals, and this represents an open invitation for interference between the various signals.

This compromise solution is entirely unacceptable to us at , so for our surround system we developed an arrangement in which the various signal processing sections were kept entirely apart. The system therefore comprises two specialised devices: an analogue twochannel stereo amplifier is used to process high-quality stereo signals, while the digital surround signals are processed in the surround decoder which is an independent machine.

In the  system the analogue and digital subassemblies are separated from each other completely, and this eliminates the danger of interference to the delicate analogue signals. The net result is that there is absolutely no danger of a loss in quality in analogue stereo reproduction.

To make it possible to integrate the surround decoder easily into an existing  system, we developed the  surround interface (TASI), which also provides the means to process and reproduce analogue signals, e. g. Dolby Surround encoded source material.

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.

Not even the length of the signal paths is changed; in stereo mode all signals remain in the pre-amplifier section of the amplifier, i. e. they are not forced to make a detour through the surround decoder.

When the system is used in Pro Logic II mode, the TASI interface also ensures that the decoder is looped in at the ideal point and at the optimum level in terms of signal processing, i. e. directly after the source selector switch.

An additional advantage of the TASI interface is that it makes it possible to exploit the superb output stages of a typical  stereo system for the front channels when in surround mode.

To ensure that the sound from the whole system is as balanced and harmonious as possible, the output stages built into the decoder are identical in circuit design to our stereo output stages. This design philosophy ensures identical frequency, phase and transient behaviour on all channels, combined with perfectly balanced dynamic characteristics.

The  surround philosophy also provides further advantages: two separate pre-amplifier circuits are present, each with its own volume and tone control functions: a stereo pre-amplifier and an independent sixchannel pre-amplifier in the surround decoder.

It is therefore possible to adjust the levels and tone settings separately to meet the different requirements for stereo and surround modes. When you switch mode, the correct settings automatically take effect.

Dolby Pro Logic IIx Surround

In this process several independent signal channels (left, centre, right and surround (rear)) are recorded using two channels and a special encoding process. Since this process only requires two recording channels, it is compatible with many picture / sound systems which are already widely in use (CD, video recorder, TV etc.).

The information is decoded at playback time and reproduced in the listening room via four (left, right, 2 x rear) loudspeakers, although five speakers (with an additional front centre speaker) are preferable. Dolby Pro Logic encoded material is currently available mainly in the film and video arena, recorded on video cassettes and DVDs, but a large number of television programmes are now being produced and transmitted using Dolby Surround.

DTS Neo:6

The DTS Neo:6 process can be used both for encoded stereo material (see Dolby Pro Logic II Surround) and also for un-encoded stereo material.

The Neo:6 decoder generates – according to setting - up to 6 channels (left, centre, right, 2 x side, back centre) from this; the back centre channel can also be reproduced by 2 separate speakers if they are available.

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.

In comparison with Dolby Pro Logic II, Dolby Digital provides two independent surround channels which generate genuine spatial stereo sound, offering the same realistic stereo reproduction as provided by the front channels.

The integral Dolby Digital decoder provides the means of obtaining a genuine digital Dolby stereo cinema presentation in your own living room. The discrete digital recording process and the five playback channels guarantee a very wide dynamic range and accurate spatial orientation.

The dynamic range is the difference in volume between the quietest and loudest passages of a recording. The original soundtrack of a film generally features an extremely wide dynamic range which the surround receiver can reproduce in full.

Unfortunately not all listening rooms, and not all times of day, are suitable for exploiting the full dynamic range. For example, it may be necessary to take your neighbours’ feelings into account - especially in the late evening hours.

For this reason it is possible to reduce the dynamic range of Dolby digital encoded sound sources in such a way that quiet passages (e. g. whispered conversations) are reproduced somewhat louder, while loud passages (e. g. massive explosions) are reduced in volume slightly (see 'Main Menu').

STEREO / MONO mode:

dts Digital Surround

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.

The six channels (5.1) are encoded / decoded in original quality, i. e. with 20-bit resolution, and recorded using only slight data compression. The 5.1 loudspeaker configuration, currently the standard arrangement for home cinema systems, is ideal for playback.

Dolby Digital Surround EX

Dolby Digital Ex is an expansion of the Dolby Digital process. In order to optimise the spatial reproduction further, the surround speakers are set up to the sides of the listening position, and supplemented by one or two additional back loudspeakers (if 2 back speakers are used, both of them reproduce the same signal).

Dolby Digital EX generates six full-range channels from the 5.1 signal. This is achieved by a matrix decoder which produces a third surround channel from the two surround channels of the 5.1 signal. Dolby Digital EX works best with film and sound material encoded with extra Dolby Digital EX.

dts ES / discrete

DTS ES is an expansion of the dts digital surround

process. The surround loudspeakers are supplemented by back speakers in a similar way to Dolby Digital EX. The sound signal is produced during the decoding process from the surround channels by means of an additional stage.

In contrast, DTS ES discrete produces the sound channel for the back speakers from a sixth channel which is recorded completely separately.

Page 54

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.).

These sound field simulations are based on an accurate analysis of the room acoustics of a number of popular room and hall types.

The digital signal processor of your decoder is capable of simulating and reproducing the characteristic sound of these venues.

For example, if you select the HALL setting while watching a rock concert on television, you will have the illusion of sitting in the middle of the audience.

Please note that it is important to set the sound field which is appropriate for the material to which you are currently listening. It makes no sense at all to select a sports stadium if you intend listening to a concert of chamber music, or an intimate club atmosphere for a rock concert.

Your DD 1535 R can generate the following sound fields:

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 produced in this way generates an immediate, energy-charged atmosphere which is a great choice for any party.

Note:

With the Dolby Digital EX / DTS ES decoder the signal is also reproduced by the centre and back speakers.

Hall

A resonant concert hall with reflections from all directions. Ideal for reproducing a large orchestra, or the live atmosphere of a large rock concert hall - an excellent choice for highly dynamic rock music.

Opera

This program combines the complete spectrum of clear voice reproduction with the full sound reproduction of an orchestra, without any unnatural echo. For better orientation the room sound is restricted slightly towards the rear.

Arena

Sound image with a narrow presence in the front region. Commentators and dialogues are localised on the screen. The rear resonance provides the impression of the public in the stadium. This sound field is also suitable for TV shows and music transmissions.

Club

The characteristic cellar jazz club atmosphere, with a pattern of sound reflection which is dominated by large floor and wall surfaces. Also good for simulating small halls.

Church

Simulation of the acoustic conditions of a large church with a long resonant period. This sound field is the perfect choice for sacred organ music.

MCH-IN

If the MCH-IN input is assigned to the active source. In this case the sound signal of the Multi-channel input is used.

Dolby Headphone

Dolby Headphone is a system which provides a form of spatial sound image even with conventional stereo headphones.

Method of working:

When a stereo signal is reproduced via two loudspeakers set up in front of the listening position, the listener perceives the music to be spread out over the area between the right and left speakers, rather than directly from the two loudspeakers themselves.

The sound image appears in this way because of sound reflections: the sound from the front speakers reaches the ears directly, but is also reflected around the room, and by the listener’s shoulders and head.

The effect is amplified by the fact that the sound from the right-hand speaker reaches the left ear as well as the right ear (and vice versa), albeit with a slight delay.

The net result of these two processes is that it is possible to locate individual sound sources spread out across the front of the listening area.

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.

Dolby Headphone goes even further than this, and incorporates the rear channels which are present in 5.1 /

7.1 material, providing a genuine cinema-like atmosphere even with conventional stereo headphones.

Three different types of room can be selected, so that the listener can match his or her personal preference to the type of music signal being reproduced:

- DH1 (reference room): small room with pronounced acoustic damping;

- DH2 (living room): small room, but with less pronounced damping;

- DH3 (large room): larger room with more diffuse sound distribution.

If we attempt to reproduce the same signal using conventional headphones, the sound from each channel reaches the associated ear of the listener, but not the opposite ear. Furthermore the reflections in the room and the shoulder area of the listener simply do not occur.

The result of this is that the music reaches the listener directly from right and left, and therefore seems to come from inside the head rather than being spread out in front.

This is the reason why many people find headphone listening an unnatural experience.

Loudspeaker configurations for the DD 1535 R

The DD 1535 R features a digital decoder which is capable of decoding all sound formats currently in use. The output can be via a stereo speaker pair, a three-channel (stereo + centre) set or a 5, 6 or 7-channel surround loudspeaker set.

Regardless of the loudspeaker configuration you use in your home, the DD 1535 R ensures that no recorded sound information is ever lost.

For example, if a 6.1 recording is played back using a 3.0 loudspeaker set (front left, front right, front centre), the DD 1535 R mixes the rear channel information onto the loudspeakers which are actually present, maintaining correct levels and phase. The information of the LFE (Low Frequency Effects) channel, i. e. of the 1. channel, is also mixed onto the channels which are present. You therefore hear everything contained in the original recording. However, if rear speakers are not present in your system, the surround effects cannot be reproduced. You therefore do not sit in the middle of events, but more as if in a theatre in front of an acoustic stage, on which the action takes place.

For the genuine surround experience you require at least a 5-channel loudspeaker set - with or without a sub-woofer.

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. It is also essential to calibrate the loudspeakers so that they reproduce the signals at exactly the right volume. This ensures that sound effects take place exactly at the position intended by the film director. With the loudspeaker con-figuration menu you can also compensate for differences in sound between individual loudspeakers, e. g. when speakers have to be set up in the corners of the room. To simplify the speaker configuration process as much as possible the SR 1535 R features an 'Assistant' which carries out most of the work for you fully automatically, i. e. level calibration, tone settings and speaker distances (see the chapter 'Auto Setup').

Picture norms, connecting AV devices to the DD 1535 R

There are several different picture norms designed for transferring video data. The most common ones are: Video (also sometimes referred to as FBAS or CVBS), SVideo (also known as Y/C or S-VHS) and Component Video (common abbreviations YUV, Y Pb Pr or Y Cb Cr).

Video is supported by virtually all source devices, TV sets, monitors and video recorders. It is therefore the most universal method of connecting video devices to each other, but unfortunately also provides the worst quality of all.

S-Video offers a significant improvement in picture quality over Video. If monitor and source device permit, the S-Video connection should always be preferred.

The absolute best picture quality is obtained using Component Video. However, Component Video is not supported by video recorders, and only a few TV sets feature the appropriate inputs. Component Video is primarily used to connect DVD players to high-quality projectors, or other large-format monitors.

The DD 1535 R offers sockets for all three video norms listed above. It can also convert Video into S-Video, and SVideo into normal video signals. As the owner of an DD 1535 R you therefore do not need to limit yourself to standard Video as the “lowest common denominator” for all your video equipment. You can connect any devices to the DD 1535 R, no matter what the picture norms, and use them together. The DD 1535 R always automatically sets the best possible connection between source, monitor and video recorder.

With its integral norm converter the DD 1535 R automatically ensures that, for example, a normal video signal is fed to a standard video recorder when making a recording, even if the source device generates S-Video signals. With the DD 1535 R this also works the other way round: if you own an S-Video recorder, the DD 1535 R always ensures that an S-Video recording signal is available for it - regardless of whether the source device supplies an S-Video signal or only a standard Video signal.

The DD 1535 R also carries out a norm conversion for the video monitor connected to it. Regardless of what your source device generates, the correct video signal is always available for your monitor.

To ensure that the DD 1535 R is able to manage the various picture signals correctly, it is essential to enter the type of signal - Video or S-Video - which the source device supplies when you are installing each device to be connected to the machine (see the chapter 'Configuration / Video Inputs').

Available as an option: YUV converter module The YUV converter module converts all Video and S-

Page 57

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. The YUV module of your DD 1535 R features a signal bandwidth of 350 MHz, is absolutely loss-free, and is therefore prepared for future high-resolution video standards (HDTV).

When installing a device, a YUV input of the DD 1535 R must be assigned to each YUV source device connected to the system (see 'Wiring Diagram 4' and the chapter

'Configuration / YUV Inputs').

Recording with the DD 1535 R

Picture norms

To make recordings using a video recorder the source device from which the recording is to be made must be connected to the DD 1535 R using either a Video or SVideo lead. It is not possible to make recordings from source devices which are connected solely using a Component input, as video recorders are not designed to handle Component signals.

Note:

Even if you own YUV-capable source devices, you still need to connect standard Video or S-Video cables, as these signals are essential for video recordings

Glossary

AV source device

A source device which supplies sound and picture signals. The sound signals may be generated in analogue or digital form.

Center

Front loudspeaker between the two main speakers, located below or directly adjacent to the TV set.

The unit of measurement for electrical levels is the

deciBel (dB).

DSP (Digitaler Signal Processor)

The digital surround decoder employs a fully programmable signal processor. A DSP can process signals using a program stored in the program memory. The program can be updated at any time, which means that the decoder can be kept abreast of new developments.

Front-speaker

Front pair of main loudspeakers, set up to left and right of the television set.

STANDBY

The digital surround decoder can be switched on from stand-by mode at any time by pressing a button on the remote control handset.

Subwoofer

Loudspeaker designed for reproducing low bass signals. It is used for special deep bass effects which are encoded on the LFE channel in Dolby Digital and dts material. When combined with small satellite speakers they also provide a full-range bass response.

S-VIDEO

High-quality picture norm with separate brightness and colour signals. Better picture quality than standard video. However, as the colours are not transmitted separately, picture quality is not quite as good as with the RGB method.

TASI

This standard  interface makes it possible to loop a  surround decoder between the source selector

switch and the volume control of the stereo amplifier. The interface automatically detects the decoder when it is connected. In surround mode the volume and tone controls of the stereo amplifier are disabled, as these functions are assumed by the decoder.

Surround-speaker

Rear pair of loudspeakers, set up behind the listening position, designed to provide spatial sound effects.

LINK

Universal control interface by means of which all the components of a  system communicate, provided

that they are fitted with an R

LINK

control socket.

RGB

High-quality picture norm, utilising separate wires for the colour signals red, green and blue. This avoids the problem of signal contamination; RGB playback

provides the best possible picture quality.

SCART

Widely used standardised connection using a 21-pin connector. SCART leads can transfer all picture norms and additional control signals (e. g. for 3:4 / 16:9 picture format switching). Adaptors are available in specialist shops for connecting a SCART socket to other standard connectors (Cinch or Hosiden).

Update

Method of bringing the software used by the decoder’s main processor or signal processor abreast of new developments. Updating the software provides for future expansion of functions and changes to meet new requirements.

VIDEO

Standard picture norm: colour and brightness information is transmitted by a single conductor. Standard video connections are present on all AV devices.

YUV

High-quality picture norm, whereby the different colour components are transferred using separate cables, in a similar way to RGB.
