Front Panel Controls - AMC 3100a User Manual

FRONT PANEL CONTROLS
POWER SWITCH
The amplifier rs turned on by depressing the
power switch. The small indicator above the
switch will glow green. 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 wrth other audiophile products, the
rnternal 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
srgnals from your remote handset.
PHONES
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 amp[fier
functions will operate as normal.
BALANCE CONTROL
The Balan:e Control adjusts the relative levels of
the left and right channels. lt 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
soeaker.
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 degrade stereo imaging. Small
compensating changes in the setting of the
Balance Control can significantly improve the
depth and stability of the stereo image.
DIRECT SWITCH
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 be 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.
BASS CONTROL
The Bass Control adjusts the relatrve level of the
low frequencies in the sound. The electrical
resoonse of the amolifier 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 vou.
TREBLE CONTROL
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 oosition. Rotation of the
Treble Control to the right (clockwise) increases
lhe 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.
RECORD SOURCE SELECTOR
This switch selects the input signal for recording.
(to TAPE OUTPUTS on rear panel)
