INPUTS
All audio Inputs are via RCA type RCA
connectors. All the RCA 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.
1. PHONO GROUND TERMINAL
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.
2. PHONO MM/MC INPUT SELECTION
SWITCH
3. PHONO INPUT (OPTION COAXIAL
IN)
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 RCA
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 MC cartridges.
Note: 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.
4. OPT/ USB / AUXILIARY INPUT
The OPT /USB /Auxiliary input is designed for using
with Optical (OPT) or USB input located at Top Left
corner of rear panel for Hi-Res Streamers like D-
STREAM PRIMO-HD etc or and other optical
sources or for 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.
Use OPT input only. for using AUX inputs, please
take OPT or USB output connector out from
CN201
5. TUNER INPUT
The Tuner input is suitable for use with most AM/
FM tuners. Connect your tuner to the amplifier
using the RCA sockets marked
"Tuner".
6. CD INPUT
The CD input is suitable for use with any CD
player. Connect your CD player to the amplifier
using the RCA sockets marked "CD".
7. PRE OUT 1
There are two pre-outs, PRE-OUT 1
& PRE-OUT 2 for the convenience
to have the pre-amp outputs to be
connected to more others equipments.
The two pre-outs are connected in
parallel together.

8. PRE OUT 2
When you will like to connect the STEREO
PREAMPLIFIER of XP1000se to
more equipments like hooking to more
Power Amps or subwoofers, you can use
the two pre-amp outputs for the purposes.
It is very important that there is adequate
ventilation for the whole of the pre-
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.
9.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
XP1000se 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 the
XP1000se or not and set to
correct voltage. When the AC Selector
is set to 115VAC,
the XP1000se can be used in countries
with AC Power Voltage between 110V
and 120V. When the AC Selector is set to
230V, the XP1000se can be used in
countries with AC Power Voltage between
220V and 240V.
10.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.

11.OPT or USB CONNECTOR
The Hi-Res OPT 24Bit/192KHz DAC
input connector is AMC proprietary
Designed for Hi-Res Streamers like
D-STREAM PRIMO-HD etc or and other
Optical sources to create superb music
sound quality with isolated ground to

4. PHONES
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.
Special Headphone Amp Design for all
Headphones and earphones available in
the market up to 600 ohms impedance.
With AMC proprietary soft clipping circuit
topology for delivery Vacuum Tube like
Sound.
FRONT PANEL CONTROLS
1. POWER SWITCH
The preamplifier 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 preamplifier 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
infra-red signals from your remote
handset.
3. BALANCE CONTROL
The Balance Control adjusts the relative
levels of the left and right channels. 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.

5. 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 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.
6. 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 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.

7. INPUT SELECTION SWITCH 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.
8. VOLUME CONTROL
The volume control adjusts the
overall loudness level of the sound.
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.
