FRONT PANEL CONTROLS
1. 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.
2. INFRARED RECEIVER
The infrared receiver for receiving the
infra-red signals from your remote
handset.
3. 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
b e t w e e n t h e s p e a k e r s , w i t h a n y
monophonic sound (such as a radio
announcer's voice) appearing as a
p h a n t o m i m a g e c e n t e r e d m i d w a y
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.
4. 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 to
your loudspeakers will be cut and all the
amplifier's functions will operate as
normal.
5. MUTE/NORMAL/DIRECT SWITCH
By turning the Direct/Mute switch to
"Mute" it is possible to cut the output to
your loudspeakers, a feature which will
prove useful in situations where a lower
volume level may be required for short
periods (e.g. for a phone call etc.)
If required, the tone controls can be
completely by-passed with a resultant
increase in sound quality. To do this
simply turn the Mute/Normal/Direct switch
to the "Direct" position.
With the Mute/Normal/Direct 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.
6. BASS CONTROL
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.
7. TREBLE CONTROL
The Treble Control adjusts the relative
level of the high frequencies in the sound.
The response of
when the control is set in the detent or 12
