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.
The infrared receiver for receiving the
infra-red signals from your remote
handset.
The headphone socket will accept any
headphones fitted with a standard
1/4"(6.35mm) stereo jack plug.
When
Headphones are in use, the output will be
cut and all the amplifier functions will
operate as normal.
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

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 degrade stereo
imaging. Small compensating changes in
the setting of the Balance Control can
significantly improve the depth and
stability of the stereo image.
When this button is pressed the Bass and
Treble circuits are completely bypassed,
restoring precisely flat frequency
response. When this button is pressed
again, the switch will turned off, the tone
controls, operate normally. By adjusting
the tone controls and then switching them
in and out of
the signal path, you can
evaluate their effect on the sound.
The Bass Control adjusts the relative
level of the low frequencies in the sound.
The electrical response of the amplifier is
flattest when the control is set in the
detent or 12 o'clock position. Rotation of
the knob to the right (clockwise)
increases the level of low frequency
sounds, and rotation counter-clock-wise
decreases their level. Adjust the Bass
Control to achieve the tonal balance that
sounds most natural to you.
The Treble Control adjusts the relative
level of the high frequencies in the sound.
The response of
the amplifier is flattest
when the control is set in
the detent or 12 o'clock position. Rotation
of the Treble Control to the right
(clockwise) increases the level of high
frequency sounds, and rotation counter-
clockwise decreases their level. Adjust
Treble Control to achieve the tonal
balance sounds most natural to you.
