OPERATING INSTRUCTIONS
DD 1535 R
2
Welcome.
We are delighted that you have decided to purchase a  product. With the addition of the digital surround decoder to
your 

 Hi- i 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
1)
and dts
2)
encoded television
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. or 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- i 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 V 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
LINK
socket!

In normal use the headphone volume knob is recessed

from the front panel and can then easily be rotated.
You can now adjust the volume of the headphones
independently of the loudspeaker output stages.
When you are satisfied with the level, push the knob
back into the front panel under light pressure. It will
automatically engage in the recessed position.

PHONES
(headphone socket)
Socket for stereo headphones with a 3.5 mm Ø barrel
plug and an impedance of at least 50 Ω. The DD 1535 R
features a separate high-quality headphone amplifier,
independent of the loudspeaker output stages.
Note:
If the loudspeakers are switched on, the headphones
always supply a STEREO signal, regardless of the
selected mode of operation.
If the loudspeakers are switched off, a simulated
surround signal (DOLBY Headphone) is available at the
headphone output if a surround mode is selected.
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
PREAMPPREAMP
PREAMP
After two minutes in stereo mode the decoder
automatically switches to stand-by mode, as it is
redundant in stereo mode.
You can switch on the decoder again at any time by
pressing the 

 button briefly; it then reverts to
stereo mode.

Remote control of the Surround Decoder
General information
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- i mode.
The decoder receives its remote control commands via the
R
LINK
master device. Press the 

 button to switch it
on; it switches itself off when the Master device is turned off.
In the drawings some of the buttons are filled in
(

remote control of the decoder. The other buttons have no

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 Main Menu contains all the functions you will need
for everyday use of the decoder. You can call it up at any
time by briefly pressing one of the remote control buttons


 or 

When you install your surround system, it is important to
set up all the audio and video components and adjust
them to match each other correctly, and to match the
acoustic qualities of your listening room. These tasks are
carried out in the Configuration Menu .
If a television is connected to the decoder, all the menus
are displayed page by page on the television screen; at
the same time they are displayed line by line on the
decoder’s integral screen.
The following table shows how the menu control system
is operated using the remote control buttons, or the
