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
i n f r a - r e d

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

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
h e a d p h o n e s
f i t t e d
w i t h
a
s t a n d a r d
1/4"(6.35mm)
stereo
jack
plug.
When
Headphones
are
in
use,
the
output
to
your loudspeakers will be cut and all the
a m p l i f i e r ' s
f u n c t i o n s
w i l l
o p e r a t e
a s
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
w h e n
t u r n e d

T h e
f l a t t e s t
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
t h e
k n o b
t o
t h e
r i g h t
( c l o c k w i s e )
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
the amplifier is flattest
when the control is set in the detent or 12
