Source selection

• To select a listening source, press either the

corresponding button on the unit or on the remote
control. The yellow LED next to the respective
button on the unit comes on and the display
indicates the selected source e.g.

TAPE

D.O.T. (Direct Operation Technique)

An "intelligent" data bus connection in your unit
makes it possible for individual components of this
series to "communicate" with each other.
The D.O.T. function allows automatic input selection
by the unit.
• E.g.: as soon as you press the CD player

PLAY

button, the tuner

STATION

1 2

buttons or the

cassette deck

PLAY

button, the unit

automatically switches to the corresponding input.

• To take advantage of this capability, all auxiliary

units must be connected via the bus lines (orange
connectors), and the D.O.T. function must be
active (D.O.T. switch on).

If D.O.T. is not active, the unit functions as a normal
unit. This may be desirable, for example, if you
want to listen to a CD over headphones and would
like to simultaneously make a tape recording from
another programme source, for instance, from the
tuner.

Switching off the display

Your unit is capable of controlling the displays of all
the units connected via the bus system.
• Use the

DISPLAYS ON/OFF

button if you want to

switch off the displays. Pressing this button again
switches all displays on once more.

speakers connected to the CENTRE SPEAKER and

SPEAKERS terminals and the rear speaker RBX1-RF

(if set to SURROUND mode).

light above the button lights up.

• The stereo RF transmission can only be switched on

when the amplifier is in normal stereo or in

3-CHANNEL mode. When RF is switched on, the

yellow light above the button lights up.

In this mode, a RBX1-RF set to STEREO mode can

receive the stereo signal from the amplifier.

When SURROUND is pressed the stereo RF trans-

mission is switched off and the light above the RF

Note:

make sure that the CHANNEL selection is the

Home cinema installation

• Switch on the amplifier and press

SURROUND

select the PRO LOGIC mode.

• Set the 2-position slide switch on the back of the

speaker to

SURROUND

– In this mode the audio signal of the speaker is

controlled by the amplifier and the speaker does not

react to its remote control.

Multi-room installation

The RBX1-RF can also be used as a stereo speaker in

a second room.

• Set the 2-position slide switch on the back of the

speaker to

STEREO

– In stereo mode, you can control the active speaker

via the supplied remote control.

NOTE:

the reach of the RF signal is 30 m in open air.

This distance will be reduced if walls are in between,

depending very much on the construction materials.

Dolby Pro Logic

Dolby Pro Logic is a coding system that enables a
set to decode 4 sound channels out of a normal
stereo signal: the centre channel for picture related
sounds, both front left and right channels for stereo
sounds and one surround channel to bring room
and depth to the scene.

Dolby Pro Logic manufactured under license from
Dolby Laboratories Licensing Corporation.
DOLBY, the double-D symbol

and ‘PRO LOGIC’

are trademarks of Dolby Laboratories Licensing
Corporation.

This full Pro Logic system needs 4 speakers that
should be connected and positioned as shown
below.

through a graphic equalizer. Please refer to your
equalizer user manual for guidance on switching off
(or defeating) the equalizer.

Adapting the Surround mode values

Both surround modes have programmed values for
centre-mode, centre and rear levels and for rear
channel time delay which are suitable for most

Direct adjustment of rear and centre level

During e.g. a film, it is possible that the special
