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
