INTRODUCTION
Your X-P200 can be connected either as a
conventional stereo amplifier, or
alternatively in “bridge” mode as a mono
amplifier with higher output power - see
page 4 and 5 for connection details.
It is intended for use with a pre-amplifier
or similar audio level source with a volume
control. We highly recommend the
matching X-Pre preamplifier also available
from Musical Fidelity.
Two stereo pairs of RCA audio input
sockets marked “
A
” and “
B
” on the rear
panel allow a choice between either of
these input sources. Simultaneous mixed
A
and
B
operation is not possible.
Whichever input is chosen, a fixed “line
level” audio output from the selected
source is available from the adjacent
OUTPUT
RCA sockets for onward
connection to another amplifier. This is to
allow for “bi-amplification” (see below).
BI-AMPLIFICATION
The X-P200’s
OUTPUT
sockets allow “bi-
amplification” of a speaker system using
suitable external amplifiers and crossover
networks. This enables the speaker drive
units to be powered separately, giving
noticeable improvement in clarity, imaging
and bass weight.
In this arrangement, typically one X-P200
is used to drive the “tweeter” (high
frequencies), and another to drive the
“woofer” (low frequencies) of each
loudspeaker enclosure. Thus, two X-P200s
would be needed for a stereo pair, or four
in bridge mode.

If in doubt about bi-amplification, please
contact your dealer for advice.
BEFORE SWITCHING ON . . . .
Plug the accessory IEC mains lead into the
rear panel socket, then the other end into a
wall outlet.
Turn the volume control on your pre-
amplifier to minimum.
OPERATION
Press the
POWER
button on the X-P200
amplifier - the blue power LED on the front
panel will light indicating that the unit is
ready for use. However, for about six
seconds no sound will be heard from your
speakers, and the red mute LED will be lit,
confirming initial mute action.
Press the
INPUT
selector button on the front
panel to switch between
A
and
B
input as
required. A corresponding blue LED above
the button will light to confirm your
selection.
Now adjust the volume control on your pre-
amplifier to obtain the preferred sound level.
If “bridge” loudspeaker operation is required,
press the
MODE
button on the front panel to
switch over to this function. A
corresponding blue LED above the button
will light to indicate which system is in use.
Press the
MODE
button again to revert to
normal stereo.
Please note that if
STEREO
mode is
accidently selected with the speakers wired
for “bridge” operation, sound will be
distorted, and lack bass. Similarly, if
switched to
BRIDGE
mode with speakers
wired for stereo operation, sound quality will
