level differences caused by the nature of the
input signal or due to room acoustics.
TONE CONTROLS
The tone controls on your AMC amplifier use low
colouration high overload margine (higher then
50V RMS.) circuitry to ensure the minimum
degradation of the music signal.
They are
designed to gradually modify the tonal emphasis
of the music and to compensate for such
problems as difficult room acoustics.
If required, the tone controls can
be
completely
by-passed with a resultant increase in sound
quality. To do this, simply turn the Direct/Phones
switch to the 'Direct' position.
With the Direct/Phones switch in the 'Normal'
position, the tone controls will cut their respective
frequencies when turned anti-clockwise and
boost them when turned clockwise. The flattest
response is found when
the
controls are in
the
'12 o'clock' position. (DETENTED POSmON)
PHONES
The headphone socket will accept any
headphones fitted with a standard quarter inch
(6.35mm) stereo jack plug. For private listening
via headphones, the Direct/Phones switch
should be set to 'Phones' , thus cutting the output
to your loudspeakers. In this position the tone
controls remain active. The mute feature is also
useful for situations where the output trom your
loudspeakers needs to be cut momentarily (eg
for a phone call etc).
-TAPE RECORDING
All sourees, Disc, CD, Tuner and Aux can be
-recorded via the tape connections. To record an
input, select the required source and set your
recorder to the record mode.
To record from one tape recorder to another, the
playback recorder should be plugged into the
Aux socket, and the racording machine into the
Tape socket. The input selector switch should
be set to ' Aux'. A recording can now be made
in the normal way.

PLAYBACK
Set the Tape Monitor switch to the 'Tape'
