affordable combination of high quality
sound reproduction and comprehensive
facilities.
The integrated amplifier accepts five
inputs (Phono, CD, Tuner, Aux/USB and
Tape), is compatible with both moving
magnet and moving coil cartridges, has
full tape monitoring capabilities and also
both a direct switch, allowing the tone
control circuitry to be by-passed for
improved sound quality.
To get the best from your amplifier
please study this manual carefully.
Should you experience any problems,
please discuss them with your dealer
who has a full knowledge of AMC
products and their use in a variety of
systems.
If the mains plug is fused, fit a 3amp
fuse. Your AMC amplifier contains fuses
which are designed to protect the
amplifier and prevent the occurrence of
a dangerous fault condition. These
should only be inspected and replaced
by a conpetent engineer using the
correct replacement types.

A/C OUTLET
INPUTS
The A/C convenience outlet is fitted so
that other components can be powered
when the AC line cord of your amplifier is
plugged into mains outlet.
You must fit an Standard 3 pin plug,
available from most specialist dealers.
All audio Inputs and tape outputs are via
gold plated RCA type phono connectors.
All the phono sockets on your AMC
amplifier are marked "L" for left and "R"
for right channels, with the left channels
nearer the top of the cabinet. Your
connection leads will have a white or
black plug for left, and a red plug for right.
Note: The A/C outlet is UNSWITCHED by
the power switch on your amplifier.
The maxinum output current rating
of A/C outlet is 1A.
UNDER NO CIRCUMSTANCES SHOULD
THE CASE OF THE AMPLIFIER BE
OPENED BY ANYONE OTHER THAN A
QUALIFIED ENGINEER, AS DANGEROUS
VOLTAGES ARE PRESENT INSIDE. ANY
UNAUTHORIZED REPAIR MAY INVALIDATE
YOUR WARRANTY.
USB CONNECTOR (XIA50 only)
PHONO INPUT (OPTION COAXIAL IN)
Note:
CD INPUT
TUNER INPUT
AUXILIARY INPUT
TAPE INPUT
The USB connector is for connecting to
computer, other equipments with USB,
LAN and so the Internet.
The analog output of the USB connector
is in parallel with auxiliary input.
This input is suitable for both moving
magnet and moving coil cartridges. For
either type of cartridge the plugs on your
turntable lead should be connected to the
phono input sockets on the rear panel of
your amplifier.
A switch adjacent to the disc input
sockets allows the selection of either MM
or MC input. Facing the back of the
amplifier, move the switch to the right for
use with MM or high output MC cartridges
and to the left for use with normal(low
output) MC cartridges.
Never operate the MM/MC selector
switch with the volume control turned up
as the resultant electrical surge may
damage your loudspeakers.
To minimize hum the turntable lead
should be kept away from the mains
wiring, and any separate turntable ground
lead should be attached firmly to the
earth terminal on the rear of the amplifier.
The PHONO can be replaced with AMC
proprietary designed DAC to convert the
PHONO INPUT into a COAXIAL INPUT.
The CD input is suitable for use with any
CD player. Connect your CD player to the
amplifier using the phono sockets marked
"CD".
The Tuner input is suitable for use with
most AM/FM tuners. Connect your tuner
to the amplifier using the phono sockets
marked "Tuner".
The Auxiliary input is suitable for use with
any extra source processing a line level
output, perhaps a second tuner or CD
player, or an additional tape or video
recorder wired for replay only.
The auxiliary input is in parallel with the
analog output of the USB connector.
This input is suitable for use with most
cassette, reel to reel or video recorders.
Connect the "record" leads of your tape
recorder to the phono sockets marked
"Tape out" on the rear of your amplifier
using phono/phono leads.

6
Connect the "playback" leads of your tape
recorder to the phono sockets marked
"Tape in" on the rear of your amplifier
using phono/phono leads. If your tape
machine processing DIN outputs, then
DIN/phono leads, or a DIN/phono adaptor
can be used. If you experience level
matching problems when using DIN
connectors, please consult your tape
machine manufacturer.
Normally the pre-amplifier 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.
PRE OUT/MAIN IN
LOUDSPEAKERS
Your AMC amplifier is designed to drive
loudspeakers with a nominal impedance
of 4-8 ohms.
However,XIA30 can only drive 4 ohm
speakers by switching the impedance
selector on the rear panel of the unit to
the 4 ohm setting.
LOUDSPEAKER CONNECTIONS
AC Selector (115V or 230V)
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 "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.
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.
The AC Selector will be set to the AC
power voltage of your country from
factory. But in case if your XIA30/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
UNDER NO CIRCUMSTANCES SHOULD
THE OUTPUTS BE SHORTED TOGETHER.
Such action will damage output circuitry
and is not covered by guarantee.
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.
HEATSINK/VENTILATION REQUIRE-
MENTS

your wall AC outlet, please always check
if the Voltage selector set to the voltage of
the country you will use XIA30/XIA50 or
not and set to correct voltage. When the
AC Selector is set to 115VAC, the
XIA30/XIA50 can be used in countries
with AC Power Voltage between 110V
and 120V. When the AC Selector is set to
230V, the XIA30/XIA50 can be used in
countries with AC Power Voltage between
220V and 240V.
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.

POWER SWITCH
Note:
BALANCE CONTROL
INPUT SELECTION
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
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.
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
INFRARED RECEIVER
The infrared receiver for receiving the
infra-red signals from your remote
handset.
Recorder is routed to the loudspeakers/
headphones.
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.
VOLUME CONTROL
TONE CONTROLS

With the Direct/Mute 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.
PHONES
MUTING
TAPE RECORDING
PLAYBACK
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.
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 ect.)
All sources, Phono, CD, Tuner and Aux
can be recorded via the tape connections.
To record an input, select the required
source and set your recorder to the
record mode.
To record from one tape recorder to
another, the palyback recorder should be
plugged into the Aux/USB socket, and the
recording machine into the Tape socket.
The input selector switch should be set to
"Aux". A recording can now be made in
the normal way.
Set the Tape Monitor switch to the "Tape"
position and set your recorder into the
playback mode.
