AMPLIFIER
The amplifier is used for reproduction of radio programmes and
prerecorded cassettes, but it is also possible to use the set as an
amplifier for external microphones @ or for the sound source
connected to the AUX @ or PHONO @ input sockets.
in this way you can e.g. reproduce gramophone records by connecting
a MD record player, you can amplify your own voice (‘Public Address’)
by connecting external microphones etc. or you can mix the mi-
crophone signal with all other sound sources.
e@ Switch on the set by pressing POWER button ().
@ Connect loudspeaker boxes to the sockets @ LOUDSPEAKERS.
e@ Set SOURCE selector ({) to the required position, see —.
e@ Make the required connections (see CONNECTIONS’).

and TREBLE @).
e Adjust the stereo effect with STEREO control G0, see —.
@ At low listening levels, press LOUDNESS button @3, see —.

back the microphone MIX control! @. You may also reduce the
reproduction VOLUME, contro! @9.

STEREO control
The
STEREO
control
@
affects
the
reproduction
of
stereo
signals
through
the
power
amplifier
and
the
loudspeakers.
The
stereo
effect
is
continuously
variable,
so
the
STEREO
control
can
also
be
set
between
two
positions,
if
desired.
When
the
sound
signa!
is
mono,
the
STEREO
contro!
will
not
have
any
effect.
e@ MONO-position:
the
stereo
signa!
will
be
reproduced
in mono.
The cassette recording and the LINE OUT @ signal will be in stereo.
e
Central
position
(STEREO):
the
stereo
signal
will
be
reproduced
in
normal
stereo.
e@
SPATIAL-position:
the
channel
separation
of
the
stereo
signal
is
electronically
increased
and
the
stereo
effect
is
extended
to
a spatial
stereo
sound.
However,
the
cassette
recording
and
the
LINE
OUT
@
signal
will
remain
in
normal
stereo.
LOUDNESS button (3
Depressing
the
LOUDNESS
button
@
will
boost
the
bass
and
treble
response.
Since,
at
low
listening
levels,
the
human
ear
is
less
sensitive
to
high
and
low
tones,
switching
on
LOUDNESS
will
compensate
for
this.
