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 1) and dts 2) encoded television pro-
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 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 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 in-
cludes 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 moni-
toring 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 furni-
ture 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.

VCR-recordings using the digital sur-
round decoder
The
x
xx
xbutton on the decoder is used to select a
recording source independently of the current source
device which you are viewing or listening to.
This facility allows you to record an AV source device
(e.g. SAT receiver) while you simultaneously watch or
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) using the
x
xx
xbutton on the de-
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: 'REC' and source name.
Caution:
The record select switch on the decoder does not carry
out any picture format conversion. You must set the
recording VCR to the same picture norm as the record-
ing source.
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 automati-
cally 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
F11 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.
The decoder receives its remote control commands via
the RLINK master device. Press the


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

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 'Device Setup'.
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 but-
tons 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 characteris-
tics of a special listening source.


button on the
decoder’s front panel.
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, and
selects it every time you switch to that input.
Surround The decoder detects an encoded digital
multi-channel signal, decodes it and passes it to all the
output channels. The front panel screen displays the
current decoder mode. If the signal is analogue, the
decoder always uses Dolby Pro Logic II decoding.
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 suppres-
sed.
Mono II Mode for two-channel TV sound
Generally Channel II transmits the original sound. The
signal from Channel II is reproduced via the Centre
loudspeaker *); Channel I (original sound) is suppres-
sed.
Note:
*) If no Centre speaker is present (see 'Loudspeaker
Menu'), the Centre channel is mixed onto the left and
right main speakers.
Not all signal sources (DVDs, CDs etc.), which are Dolby
Digital or dts Digital Surround encoded contain full 5.1
information. 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'.
Sound fields:
Disco This sound field is particularly suitable for pro-
viding an even spread of sound over a dance floor, using
the front and surround loudspeakers. The sound signal is
mixed and passed to the front and surround speakers
without reflections and delays, and with equal power.
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 reproduc-
tion with the full sound of an orchestra, but without exag-
gerated reverberation. The spatial sound towards the
rear is slightly limited, in the interests of better orienta-
tion.
Stadium This sound image concentrates the “pres-
ence” 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 suit-
able 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.

11
ProLogic II mode:
This menu point enables you to set the Dolby ProLogic II
decoder to suit varying programme material.
Movie for films
Music for music
Matrix for mono programme material
Balance left/right and front/surround:
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 com-
pensate for tonal differences in the recorded material.
The setting affects all channels, and the range of ad-
justment is +/- 6dB in 1 dB increments. The current value
is displayed on the screen; 00
dB means 'Linear set-
ting'.
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'.
Loudness:
Toggles volume-dependent tone correction
(LOUDNESS) on and off. The display area of the de-
coder always shows the current status briefly in text
form; the
symbol in the display window is the per-
manent indicator that loudness is switched on.
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 be-
tween the other channels (front, rear and center). This
task is carried out in the 'Speaker Balance Setup'.
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 reproduc-
ing the full range.
Unfortunately not every listening room can cope with the
full dynamic range which the decoder is capable of re-
producing. 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.
high standard setting, moderate compression of
dynamic range.
full exploits the full dynamic range which the
sound source makes available.
Note:
Any adjustment to the dynamic range only affects Dolby
Digital encoded sound sources.

12
System Configuration
In the 'Device Setup'you can adjust the settings for all
the audio and video components of your surround sys-
tem so that they match each other perfectly, and at the
same time set them to suit the acoustic characteristics of
your listening room.
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.

The table on the left shows how the menu system can be
controlled using the remote control buttons or the buttons
on the front panel of the decoder.
•The select buttons are used to move to pre-set posi-
tions where you can enter information.
•The change buttons alter the value at the input posi-
tion.
•If there is a further menu name at the data input posi-
tion, then pressing the confirmation button calls up
the corresponding sub-menu. Otherwise the confirma-
tion button closes the menu.
All menus are displayed page by page on the screen of a
television set (if connected), and at the same time line by
line on the decoder’s integral screen.
The following section describes the menu points and

Screen brightness:
The brightness of the screen can be set to suit your
personal preference. Three brightness levels are avail-
able:

If you set either of brightness levels 1 and 2, 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 bal-
ance 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

Loudspeaker:
The 'Speaker Setup'provides the means to balance the
output signals to the loudspeakers in your surround sys-
tem. At the same time you can adjust the output of the
speakers accurately to suit the acoustic and spatial
characteristics of your listening room.
Picture norm:
In the 'Video Setup'you can set the correct picture norm
to match the picture sources connected to all the de-
coder’s video inputs and outputs.
Source:
The purpose of the 'Source Setup'is to integrate the AV
sources connected to the decoder into the overall oper-
ating system of the typical ‘R’ system. This is done by
assigning a name to every AV source which is connected
to the decoder; those names are then used from that
point on in all the decoder’s on-screen messages. You
can then define the audio / video input socket (or
sockets) on the decoder to which each device is con-
nected. Finally it is possible to assign every AV source to
a source button on the remote control handset, so that
the various machines can be selected when the system
is set to surround mode.

Speaker Setup
The first purpose of the 'Speaker Setup'is to allow you
to distribute the output signals correctly to the loud-
speakers which form part of your surround system.
If your system does not include a “full set” of supple-
mentary loudspeakers (center, rear and subwoofer), it is
important to mark the missing items as
none in the
'Speaker Setup'.
The corresponding sound signal is then mixed down onto
those channels which are present (Downmix).
The last three menu points enable you to adjust the
loudspeakers to suit the acoustic and spatial character-
istics 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.).
Main size:
Defines the size and bass capacity of the main left and
right front loudspeakers. Select one of the following set-
tings: *)
satellite for small speakers whose bass reproduc-
tion is necessarily restricted. The low bass
content (below 80 Hz) of the main channel
signals is mixed down onto the subwoofer,
if present.
full range for larger speakers. The full frequency
range is passed on to the main speaker
channels without restriction.
Center size:
Defines the size and bass capacity of the center
speaker. Select one of the following settings: *)
none if no center loudspeaker is present. The
center channel is mixed down onto the left
and right main loudspeakers.
satellite for small speakers whose bass reproduc-
tion is necessarily restricted. The low bass
content (below 80 Hz) of the main channel
signals is mixed down onto the subwoofer,
if present.
full range for a center speaker of about the same
size as the main loudspeakers. The full
frequency range is passed on to the center
channel without restriction.
Note:
If your system does not include a center speaker, the
main loudspeakers should be set up not too far away
from the TV set, and ideally should be arranged symmet-
rically about it, otherwise it will be very difficult to localise
dialogues on the television screen.

15
Rear Size:
Defines the size and bass capacity of the rear surround
loudspeakers. Select one of the following settings: *)
none if no surround loudspeakers are present. The
surround channels are mixed down onto the
left and right main loudspeakers.
Note:
Genuine surround reproduction is not possible without
rear speakers!
satellite for small speakers whose bass reproduction
is necessarily restricted. The low bass content
(below 80 Hz) of the main channel signals is
mixed down onto the subwoofer, if present.
full range for speakers which offer very good bass
reproduction. The full frequency range is
passed on to the surround channels without
restriction.
*) Note:
To avoid nonsensical settings, the system does not allow
you to set all the possible combinations (Front LS, Cen-
ter and Rear LS). The following list shows all the stan-
dard combinations, but you can modify them individually.
Standard combinations
1. Main, center and rear size: ....... Satellite
Subwoofer: ............................... on
2. Main size: ................................. Full range
Center and rear size: ............... Satellite
Subwoofer: ............................... off
3. Main and rear size: ................... Full range
Center size: .............................. Full range
or ........................ Satellite
Subwoofer: ............................... on
Subwoofer:
In this menu point you set whether a subwoofer is pres-
ent in your loudspeaker system. Select one of the fol-
lowing settings:
on If a subwoofer is present. The signals in the
Low Frequency effect channel (LFE), and all
other low-frequency bass signals (below
80 Hz) which are not within the compass of
the full-range loudspeakers, are passed to the
subwoofer channel.
off If no subwoofer is present. The signals from
the Low Frequency effect channel (LFE) and
all other low-frequency bass signals (below 80
Hz) are mixed down onto the main loudspeak-
ers.
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.
Speaker position:
Activating this menu point leads to a further menu in
which you can define the position of the loudspeakers,
i.e. you can enter the distance from the listening position
to each loudspeaker separately. This enables the de-
coder to compensate for timing discrepancies due to
differences in speaker location (see 'Speaker Position
Setup').
Noise sequencer:
Activating this menu point leads to a further menu in
which you can set the balance between the volume of all
the loudspeakers (see 'Speaker Balance Setup').
Tone adjust:
Activating this menu point leads to a further menu in
which you can adjust the tonal balance of the loud-
speakers (see 'Tone Control Menu').

16
Speaker Position Setup
In the 'Speaker Position Setup'you can enter the dis-
tance from the listening position (in 0.3 m increments) for
each loudspeaker separately.
This enables the decoder to compensate for timing dis-
crepancies due to differences in speaker location.
Measure the distance between the listening position and
the loudspeakers in your surround system, and enter the
measured distances.
As the illustration shows, you use the select buttons to
move to the input positions in the following sequence.
Output channels not in use (see 'Speaker Setup') can-
not be edited.
•Main loudspeaker front left (FL)
•Center loudspeaker front center (Center)
•Main loudspeaker front right (FR)
•Surround loudspeaker rear right (SR)
•Surround loudspeaker rear left (SL)
•Active subwoofer (any position) (Sub)
Use the change buttons to enter the measured distance
in increments of 0.3 m.
Note:
The maximum distance of a loudspeaker to the listening
position is 12 m. For acoustic reasons greater distances
cannot be recommended, and the system cannot com-
pensate for timing errors over a range greater than 12 m.

17
Speaker Balance Setup
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 Setup'is to adjust
the level of all the channels.
When you activate the 'Speaker Balance Setup'you will
hear a hiss from the left main loudspeaker lasting two
seconds. You will find the data input position after the
first menu point.
'FL: 00 '.
As the illustration shows, the hiss is reproduced on all
the channels in turn, in each case lasting about two sec-
onds:
•Main loudspeaker front left (FL)
•Center loudspeaker front center (Center)
•Main loudspeaker front right (FR)
•Surround loudspeaker rear right (SR)
•Surround loudspeaker rear left (SL)
The system skips any output channels which are not in
use (see 'Speaker Setup').
When the hiss is sounding on a particular channel, the
on-screen menu indicates the corresponding input posi-
tion. You can now alter the value within the range –10
to +10 using the change buttons. You can immediately
hear the result of any change you make.
If you alter the volume, the hiss continues on that chan-
nel for a further two seconds before moving on to the
next channel. The input position then changes accord-
ingly.
You can override the automatic cycling process by se-
lecting a particular channel using the select buttons; you
can then adjust its level as you wish.
Take your time to set all the channels to give as even an
impression of volume as possible!
Note:
The hissing sound used for this is not suitable for as-
sessing bass volume; the volume of the subwoofer
channel can be adjusted in the menu point 'Subwoofer
level', which is part of the 'Main Menu'.
The levels you set for each channel are stored for use
when the surround system has been selected, and ap-
plies to all surround modes.

18
Tone Control Menu
The decoder features an active tone control system
(+/- 6 dB) whose purpose is to compensate for the un-
wanted 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 speak-
ers.
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.
Once you have activated this section of the menu, you
will find the data input position after the first menu point.
'FL TB: 00 '.
You can now alter the value within the range –06 to
+06 using the change buttons; any change you make is
immediately audible.
Select the input position using the select buttons.
As the illustration shows, you can cycle through the input
positions in the following order:
Output channels not in use (see 'Speaker Setup') can-
not be edited.
•Main loudspeaker front left Treble (TB)
•Main loudspeaker front left Bass (BS)
•Center loudspeaker front center Treble (TB)
•Center loudspeaker front center Bass (BS)
•Main loudspeaker front right Treble (TB)
•Main loudspeaker front right Bass (BS)
•Surround loudspeaker rear right Treble (TB)
•Surround loudspeaker rear right Bass (BS)
•Surround loudspeaker rear left Treble (TB)
•Surround loudspeaker rear left Bass (BS)
Set values for treble (TB) and bass (BS) on all channels
which gives as well-balanced a sound image as possible.
Note:
Adjusting the tone controls has an influence on the over-
all level of that channel. After making a change here we
recommend that you call up the 'Speaker Balance
Setup'again so that you can check the balance of all
channels and make corrections if necessary.

19
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 'Video Setup' you can set the picture norm
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 dif-
ferent 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.
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, S-
Video and RGB; RGB provides the best picture quality.
The least problematic arrangement is for all the compo-
nents to use the same picture norm. If the TV set con-
nected to your surround system has a priority RGB cir-
cuit, mixed operation is also possible (e.g. DVD player «
RGB, Set-top box «Video; VCR «S-Video); see ex-
ample.
TV out:
RGB / Video For TV sets with RGB or Video sock-
ets.
S-Video For TV sets with S-Video sockets.
DVD in:
RGB / Video If the DVD supplies an RGB and Video
signal.
S-Video If the DVD supplies an S-Video signal.
Set-top in:
RGB / Video If the set-top box supplies an RGB and
Video signal.
S-Video If the set-top box supplies an S-Video
signal.
VCR in:
Video If the video recorder only supplies a
Video signal
S-Video If the video recorder supplies an S-
Video signal
Example:
In the example mentioned above, the TV out output
should be set to RGB / Video . The decoder automati-
cally converts the incompatible S-Video signals to the
Video format.
Note:
Some AV source devices make available a switch volt-
age at their SCART output which switches the TV set
connected to it from television reception to SCART pic-
ture and sound reproduction; it can also be used to
change the picture format (4:3 / 16:9). Different makes of
TV set interpret the switch voltage in different ways; see
your TV operating instructions for details.
•In RGB/Video mode the switch voltage produced by
the source device is passed on to the TV out socket
unchanged.
•In S-Video mode the decoder switches on the switch
voltage at the TV out socket permanently.
If compatibility problems arise between the TV set and
the AV source devices connected to the system, we
recommend that you use the standard Video norm for all
the machines, as this is generally supported by all de-
vices. Look at 'Trouble-shooting'.

Source Setup AV source devices
The purpose of the 'Source Setup'is to integrate the AV
source devices connected to the decoder into a
'R'
system. For this purpose the sources are sub-divided
into three groups:
1. High-quality pure stereo sources (sound only),
2. A/V sources (picture and sound),
3. Combination sources; i.e. machines which supply
both a picture and high-quality stereo sound.
To ensure that sound and picture quality are always
optimum, these device groups are integrated into the
system in different ways (see also the section enti-
tled 'The
Surround System'). Please note the
following points:
Stereo sources (e.g. tuners) should be connected di-
rectly to a pre-amplifier input. They are selected by the
corresponding source button on the front panel, or on the
remote control handset.
A/V sources (e.g. standard video recorders) should be
connected directly to one of the decoder’s AV inputs
(SCART or Cinch). They can then be selected by the
2
22
2button on the front panel, or by the 

but-
ton on the remote control handset.
If you have assigned the source device to a direct select
button in the 'Source Setup', then you can select it di-
rectly by pressing the appropriate source button.
Combination source devices (e.g. DVD players and
set-top boxes) provide both an analogue stereo signal
and a digital surround signal.
The
surround design philosophy enables you to
connect the analogue stereo output of a combination
source device to a pre-amplifier input.
For example, if your DVD player is playing a DVD in
surround mode, the picture signal is passed to the
decoder via a SCART lead, and the sound signal via a
digital connection.
In surround mode you select the DVD player by pressing
the
2
22
2button on the front panel, or the 


button on the remote control handset.
If you have assigned the DVD player to a direct select
button in the 'Source Setup', then you can select it di-
rectly by pressing the appropriate source button.
CDs can be played on the DVD player in high-quality
stereo mode via the direct connection to the amplifier; in
this situation the decoder is removed from the signal
path.
In stereo mode you select the DVD player by pressing
the corresponding source button on the pre-amplifier’s
front panel, or on the remote control handset.
