FEATURE
The AMC Integrated Amplifier XIA100 /
XIA150 offers, in an innovative and
elegant design, an affordable combination
of high quality sound reproduction and
comprehensive facilities.
The amplifier accepts six inputs (Option,
iPod / DAC, CD, Tuner, Video, Aux) and
has full recording capabilities.
To get the best from your amplifier please
study this manual carefully. Should you
experience any problems, please discuss
with your dealer who has a full knowledge
of AMC products for uses in a variety of
systems.
Your AMC amplifier is set to work on your
local mains supply voltage. Check that
your local mains supply voltage agrees
with the voltage setting indicated on the
back panel of the amplifier. If not, please
contact your dealer or national distributor
for details on how to proceed further.
The cores of the mains lead are colored
in accordance with the following code:
Blue -Neutral
Brown -Live
Export units for certain markets
have molded mains plugs fitted as
standard.
As the colors in the mains lead may not
correspond with the colored markings
identifying the terminals in your plug,
proceed as follows:
The wire which is colored blue must be
connected to the terminal which is
marked by the letter N, or colored black
or blue. The wire which is colored brown
must be connected to the terminal which
is marked by the letter L, or colored red or
brown.
If the mains plug is fused, fit a 5 amp
fuse. Your AMC amplifier contains fuses
which are designed to protect the
amplifier and prevent the unit from the
occurrence of a dangerous fault
condition. These should only be
inspected and replaced by a competent
engineer using the correct replacement
types.

switch between MM & MC, please open
top cover and switch the MM/MC switch
on PHONO Module to the position you
will like to select. The PHONO Module is
located behind PHONO INPUT RCA
Jacks fixed to the side chassis. The plugs
on your turntable lead should be
connected to the disc input sockets on
the rear panel of your amplifier.
The Ground Terminal is for you to
connect ground wire of your turntable in
order to eliminate possible interference
and hum loop for best possible sound
quality.
The PHONO Module can be replaced
with AMC proprietary designed DAC to
convert the PHONO INPUT into a
COAXIAL/OPTICAL INPUT.

player, or an additional video source
wired for replay only.
HEATSINK / VENTILATION
REQUIREMENTS
The heat produced by your AMC amplifier
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.
PRE OUT/MAIN IN
LOUDSPEAKERS
LOUDSPEAKER CONNECTIONS
Normally the preamplifier and power
amplifier sections of this unit are
connected together via factory-installed
U-shaped metal jumpers that bridge the
PRE-OUT and MAIN-IN jacks. Check to
be sure that they are fully inserted into
the jacks and that nothing is touching
them.
By switching OFF the power and
removing the metal jumpers, you can
connect a signal processor such as a
surround-sound decoder or an electronic
crossover in the path between preamp
and power amp. Connect a cable from
PRE-OUT to the processor's input and a
second cable from the processor's output
to MAIN IN.
Your AMC amplifier is designed to drive
loud-speakers with a nominal impedance
of 4-8 ohms.
The USB feature is optional.
The USB connector is for connecting to
computer, other equipments with USB,
LAN and so the internet.
The loudspeaker output terminals will
accept 4mm (banana) plugs, spade
connectors, pin connectors or bare wires.
Connect the negative side(usually black)
of your left hand loudspeaker lead to the
black terminal of the two terminals
marked "L" 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 "L".
Repeat this operation for the right hand
loudspeaker.
Your AMC amplifier is capable of
generating high peak currents, so all
connections must be checked to avoid
inadvertent short circuits and to ensure a
good clean contact.
Such action will damage output circuitry
and is not covered by guarantee.
USB (OPTION)
RS232
AMC CARD (OPTION)
ETHERNET (OPTION)
XIA100/XIAS150 can be hooked to a
control system through the AMC Card,
RS232 or Ethernet connector to accept
commands from your system controller.
For details of RS-232 commands, please
refer to the RS-232 appendix.
UNDER NO CIRCUMSTANCES SHOULD
THE OUTPUTS BE SHORTED TOGETHER.

BALANCE CONTROL
DIRECT SWITCH
BASS CONTROL
TREBLE CONTROL
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.
The infrared receiver for receiving the
infra-red signals from your remote
handset.
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 amplifier functions will
operate as normal.
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 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.
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 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.
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.
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 position. Rotation
of the Treble Control to the right
(clockwise) increases the 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.

INPUT SELECTION
VOLUME CONTROL
The rotary input selector switch selects
which input signal (Option,
CD, Tuner, Video, AUX) is fed to the
power amplifier.
The volume control adjusts the overall
loudness level of the sound. It has no
effect on the level of the signals fed to the
REC OUT jacks for 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.
