9. LOUDSPEAKERS
Your AMC
amplifier
is
designed
to
drive
loudspeakers
with
a
nominal
impedance
of 4-8 ohms.
LOUDSPEAKER CONNECTIONS
The
loudspeaker
output
terminals
will

of your left hand loudspeaker lead to the

marked "left" on the rear of your amplifier.
The other side of your left hand speaker
lead (the positive side or red) should be
connected
to
the
red
terminal
marked
"left".
Repeat
this
operation
for
the
right
hand loudspeaker.

so
all
connections
must
be
checked
to
avoid
inadvertent short circuits and to ensure a
good clean contact.
UNDER NO CIRCUMSTANCES SHOULD
THE OUTPUTS BE SHORTED TOGETHER.
Such
action
will
damage
output
circuitry
and is not covered by guarantee.
HEATSINK/VENTILATION REQUIRE-
MENTS
The heat produced by your AMC amplifier
during
normal
operation
is
dissipated
by
an during normal operation is dissipated
by
an
internal
finned
heatsink.
It
is
perfectly
normal
for
your
amplifier
to
becomes quite warm and to radiate heat
when in use, especially if it is run near full
power. However, if it becomes too hot to
touch, switch off at once and contact your
dealer.
It is very important that there is adequate
ventilation for the whole of the amplifier.
Do
not
place
the
unit
on
a
rug
or
other
soft
surface
that
it
could
sink
into,
obstructing the air inlets on its underside,
and
take
care
not
to
obstruct
the
outlet
grille on the top cover.
10. AC Selector (115V or 230V)
The
AC
Selector
will
be
set
to
the
AC
power
voltage
of
your
country
from
factory. But in case if your XIA30t/XIA50
is not received directly from factory or you
move from one country to the other, the
AC
selector
might
be
set
at
different
voltage. So, before plug power cord into
your wall AC outlet, please always check
if the Voltage selector set to the voltage of
the country you will use XIA30t/XIA50 or
not and set to correct voltage. When the
A C
S e l e c t o r

11 5 VA C ,
t h e
XIA30t/XIA50
can
be
used
in
countries
with
AC
Power
Voltage
between
110V
and 120V. When the AC Selector is set to
230V,
the
XIA30t/XIA50
can
be
used
in
countries with AC Power Voltage between
220V and 240V.
11. AC RECEPTACLE
The AC RECEPTACLE is for you to plug
in
with
power
cord
attached
in
the
packing
or
you
can
plug
in
with
other
power cord with your preferences.
