With the digital surround decoder you can play Dolby Surround, Dolby Digital grammes, 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 nonencoded 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 three 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.

Hi-Fi system you are expanding it to embrace a completely new dimension:

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 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.

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

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:

Dynamic range:

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.

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 first step is to select a sound source which you wish to use as the basis for adjusting the tone controls. Make sure that the sound source you choose is active on all the channels, so that the sound image is typical of your listening habits, and any changes you make to the tone controls are immediately audible in that setting.

Video Setup

Optimum picture quality is only possible if the picture norms of all the video components in the system are set up to match each other, and if the correct cables (SCART, video-coax) for the selected picture norm are used. In the for all the decoder’s video inputs and outputs to match the capabilities of the devices connected to it. Many AV source devices can generate a picture signal using different picture norms (Video, S-Video, RGB), and in this case the picture norm you wish to use must often be set in a menu on the AV source device. If you are not sure of this, study the operating instructions supplied with the source device and the TV set.

'Video Setup'

you can set the picture norm

There is a large number of different picture norms on the market, but not all of them are supported by all AV source devices and TV sets. The decoder is designed to handle the most widely used picture norms: Video, SVideo and RGB; RGB provides the best picture quality.

The least problematic arrangement is for all the components to use the same picture norm. If the TV set connected to your surround system has a priority RGB circuit, mixed operation is also possible (e.g. DVD player « RGB, Set-top box « Video; VCR « S-Video);

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. We 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 equipment. 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

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 decoder.

Liquid or foreign bodies must never be allowed inside the cooling slots. 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.

Installation and wiring

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 decoder 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

With the exception of the connections and procedures described in these instructions, no work of any kind may be carried out on the decoder 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 cialist 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 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 unit 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.

Connect the equipment into an outlet on a circuit different form that to which the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

Installation, using the unit for the first time

General notes on setting up the unit:

Carefully unpack the digital surround decoder and store the original packing materials carefully. The carton and packing are specially designed for this unit and will be needed again if you wish to move the equipment at any time.

Please be sure to read the safety notes in these instructions.

If the unit gets very cold (e.g. when being transported), condensation may form inside it. Please do not switch it on until it has had plenty of time to warm up to room temperature, so that any condensation evaporates completely.

Before placing the unit on a sensitive surface, please check the compatibility of the lacquer and the unit’s feet at a non-visible point.

The decoder should be placed on a rigid, level base. When placing the unit on resonance absorbers or decoupling components make sure that they do not compromise the stability of the unit.

The unit should be set up in a dry, well-ventilated site, out of direct sunlight and away from radiators.

The unit must not be located close to heat-producing objects or devices, or anything which is heat-sensitive or highly inflammable.

When installing the unit on a shelf or in a cupboard it is essential to provide an adequate flow of cooling air, to ensure that the heat produced by the unit is dissipated effectively.

Any heat build-up will shorten the life of the unit and could be a source of danger!

Before you start:

Before you connect your digital surround decoder to your

Notes on connections:

• Be sure to push all plugs firmly into their sockets. Loose connections can cause hum and other unwanted noises.

• Deploy all mains leads, loudspeaker cables and remote control leads as far as possible from low-level leads (inter-connects) and aerial cables. Never route them over or under the decoder.

• Connect the unit to a correctly earthed mains socket using the mains lead supplied.

• To achieve maximum possible interference rejection the mains plug should be connected to the mains socket in such a way that phase is connected to the mains socket contact marked with a dot (z). The phase of the mains socket can be determined using a special meter. If you are not sure about this, please ask your specialist dealer.

'POWER LINE'

• We recommend the use of the ready-to-use mains lead in conjunction with the

'POWER BAR'

ted with a phase indicator as standard.

As the decoder can be combined with a very wide range of different AV components, it must be configured carefully for each audio / video device in order to achieve optimum sound and picture quality.

We recommend that you adopt the following procedure when using the decoder for the first time:

a. Connect the TV set and the surround speakers to the

decoder (wiring diagram 1).

b. Integrate the digital surround decoder including

speakers and TV set into your existing Hi-Fi system (wiring diagrams 2).

• Finally connect the mains lead and switch the system on.

• To use the decoder your television must be correctly configured. The essential settings include the following:

Choice of AV input

Some 16:9 TVs use a switch line (pin 8 of the SCART socket) to select the picture format. Use the SCART socket of the TV set which supports this method of switching, and set the TV appropriately

Use of decoder

The TV set must make the signals it receives available at the SCART socket, in order to allow you to view and hear the terrestrial programmes received via the TV set through the decoder, and also to let you see the decoder’s on-screen menu when in TV mode. On some TV sets you will have to set it for

devices connected to the TV.

Some source devices can supply a range of different picture norms, and some TV sets can only process one norm; If problems arise in this respect, it will sometimes be necessary to select the standard Video norm for all the machines in the system, as this is generally supported by all devices.

Surround sound - explanatory notes

General information:

The following section is not concerned directly with the operation of your digital surround 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 decoder 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 building. 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 center 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.

Dolby Pro Logic II Surround

In this process serveral independent signal channels (left, center, right, surround (rear) left and surround (rear) right) 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 center speaker) are preferable. Dolby Surround 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.

Dolby Digital

Dolby Digital is a digital multi-channel surround system which was developed specifically for spatial sound reproduction in connection with 35 mm cinema films. The process utilises five separate sound channels: three front channels (left, center, right) and two surround channels. A sixth independent bass effect channel is also present,

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

The decoder’s 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.

Sound field simulation

The surround processes already described require programme material which is encoded using the appropriate system, but the digital surround decoder also offers a facility to enhance the spatial effect available with conventional unencoded stereo recordings (CD, MC, VHF radio etc.).

This it does by offering a range of artificial

simulations

These sound fields are based on a precise analysis of the acoustics found in typical concert halls.

The digital signal processor of your digital surround decoder is capable of simulating the spatial sound of these halls, and reproducing it via the five channels of your surround system.

For example, if you select the 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 to 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 digital surround decoder can generate the following sound fields:

surround system

Multi-channel reproduction based on surround technology does indeed open up new worlds of experience, but the technical implementation of a multi-channel 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 highfrequency 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



, 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 assemblies 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

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 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 vantages: two separate pre-amplifier circuits are present, each with its own volume and tone control functions: a stereo pre-amplifier and an independent six-channel preamplifier 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.
