heading 'Use with the signal source selection switch'.
Recording
A recording can be made in two ways:
With the 'REC SELECTOR' recorder selection switch @in the
'source' position. The same signal will be produced at the
terminal sockets
and
loudspeakers and/or headphones.
At the same time, switch on a recorderwhich is connected to the
terminal sockets
and
or
With the 'REC SELECTOR' recorder selection switch @in the
'CD' or 'TUNER' position. The same signal will then be produced
at the terminal sockets @and @as corresponds to the selected
'REC SELECTOR' position (on condition that the signal source
is operative).
At the same time, switch on a recorder connected to the terminal
sockets
and
or

Note:
- If the recorder used has separate heads for recording and
playing back, then it is possible to monitor the recording. For
further information see the operating manual of the recorder.
- Operating the bass/treble, volume level, balance control and
loudness switch has no effect during the recording.
Listening to a different signal source whilst making a recording
If you make a recording with the 'REC SELECTOR' recorder
selection switch @in the 'CD' or 'TUNER' position, it is possible
to listen to a different signal source.
If you wish to do so, press on the amplifier the selection switch
@which corresponds to the signal source. The corresponding
indicator will light up.
If the recording fails:
An unsuccessful recording may be the result of:
faulty operation of the signal source to be recorded.
operation of the 'REC SELECTOR' recorder selection switch @.
operation of the 'DIGITAL' switch
Copying tapes
With the 'REC SELECTOR' recorder selection switch
'COPY 1 -b 2' position, a tape in recorder 1 can be copied onto
that in recorder 2.
With the 'REC SELECTOR' recorder selection switch
'COPY 2 -b 1' position, a tape in recorder 2 can be copied onto
a tape in recorder 1.
In the meantime, if required, it is possible to listen to a different
signal source.
Set the 'REC SELECTOR' recorder selection switch @ t o the
'COPY 1 -b 2' or 'COPY 2 -b 1' position.

GENERAL INFORMATION

Loudspeaker connection
Loudspeakers must be connected in pairs to the 'SPEAKERS'
loudspeaker connections
system A or system B is used or loudspeakers with an imped-
ance of 8 to 16 ohms if system A and system B are used).
In order to do this, the wires of the loudspeaker cables, which
should preferably have a minimum diameter of 1' 1 , mm
prepared by removing the insulation ( + 5 mm.) and twisting the
core wires. If necessary, remove the loudspeaker plugs to do
this. If you prefer not to do this, use suitable adaptor cables.
One of the two wires of a loudspeaker cable or adaptor cable is
marked throughout with a special marking. This may be a colour,
stripe, rib or other indication.
Bear this distinction in mind!
Connection
1. Ensure that the amplifier is switched off!
2 . Determine which group of terminals you will use (e.g. A).
3. Select the loudspeaker to be connected (e.g. the left, 'L').
This will then determine which two wires are to be connected
to which two terminals.
4. Insert the marked wire into the red terminal, the non-marked
wire into the black terminal (see Figs. 5a, 5b and 5c).
Tighten the loudspeaker terminal firmly to limit the contact
resistance between the terminal and the wire as far as
possible.
5. In exactly the same way, connect the wires of the other
loudspeaker (in this case the right, 'R') with the two other
terminals (in this case A), i.e. the marked wire in the red
terminal, the non-marked wire in the black terminal. If you do
not do this, the loudspeakers will not work 'in phase'. The
stereo reproduction will then not be correct.
6. If connecting a second pair of loudspeakers, connect these
in exactly the same way to the remaining terminals (in this
case the B terminal).
7 . Check all connections made are correct:
Uninsulated wire ends must not touch (short circuit!).
The wires must not be loose in the terminals (tighten fully).
8. Ensure that the volume control is not on MAX and only then
should you switch on the amplifier.
Positioning the loudspeakers
In order to obtain as good a stereo effect as possible, take some
time when positioning your loudspeakers. Because every room
has its own limitations, the best positioning can only be obtained
by experimenting.
The following rules should be borne in mind:
Looking from the listener's position, place the loudspeaker
connected to the 'L' terminal on the left. Place the loudspeaker
connected to the 'R' terminals on the right.
Try to keep the distance between the two loudspeakers equal
to that between each of the loudspeakers and the listener's
position.
Bass reproduction is amplified by placing the loudspeakers on
the floor or in a corner.
Treble reproduction is adversely affected by placing the
in the
loudspeakers behind objects (furniture, sunblinds, curtains,
etc.).
Try to keep the arrangement and the positioning height as
in the
symmetrical as possible.
Maintenance
The amplifier can be cleaned on the outside using a damp cloth
(not wet!). Use only water to dampen the cloth.
(impedance 4 to 16 ohms, if only
2
, must be
