TAPE MONITOR 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.
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 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

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.
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

is

the
loudspeakers/

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.
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.
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.
