FRONT PANEL CONTROLS
POWER SWITCH
The amplifier is turned on by depressing
the power switch. The small indicator
above the switch will glow blue. Before
switching on, always set the volume
control to minimum to avoid damage to
your loudspeakers.
Note:
Your AMC amplifier will play music
almost immediately after being switched
on. However, in common with other
audiophile products, the internal circuits
take some time to stabilize fully, and the
best possible sound quality may not be
obtained until the amplifier has had some
time (possibly an hour or two) to warm
up.
INFRARED RECEIVER
The infrared receiver for receiving the
infra-red signals from your remote
handset.
BALANCE CONTROL
The Balance Control adjusts the relative
levels of the left and right channels. It has
no effect on recordings being made. A
detent at the 12 o'clock position marks
the point of equal balance. Rotation of the
Balance Control to the right (clockwise)
decreases the level of the left channel so
that only the right channel is heard.
Rotation to the left shifts the sonic image
toward the left speaker.
Adjust the Balance Control to produce a
natural spread of sound across the space
between the speakers, with any
monophonic sound (such as a radio
announcer's voice) appearing as a
phantom image centered midway
between them. Recordings often contain
small errors in channel balance, typically
no more than 2dB; but this is enough to
d e g r a d e s t e r e o i m a g i n g . S m a l l
compensating changes in the setting of
the Balance Control can significantly
improve the depth and stability of the
stereo image.
INPUT SELECTION
The rotary input selector switch selects
which input signal(Phono, CD, Tuner or
Aux/USB)is fed to the power amplifier.
The selected signal is also fed to the
"Tape out" sockets for recording.
TAPE MONITOR SWITCH
The Tape Monitor switch is generally left
in the "Source" position, so that the
program selected by the input switch is
routed to the loudspeakers/headphones.
If the Tape Monitor switch is turned to the
"Tape" position, the signal from the tape
Recorder is routed to the loudspeakers/
headphones.
If your tape machine is a three head type
suitable for A/B monitoring, then turning
the Tape Monitor switch to the "Tape"
position will allow full off-tape monitoring
of the recorded signal to be carried out
via the loudspeakers/headphones.
VOLUME CONTROL
The volume control adjusts the overall
loudness level of the sound. It has no
effect on the level of the signals fed to the
TAPE OUT jacks for tape recording. The
Volume control is designed for accurate
tracking of its two channels, so that the
stereo balance will not shift noticeably as
the loudness of the sound is varied.
TONE CONTROLS
The tone controls on your AMC amplifier
use low colouration passive 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/Mute switch to the
"Direct" position.
