Installation Precautions
Your new X-A200 is designed and built to provide trouble-free
performance, as with all electronic devices it is however necessary to

with these before you connect the power to your X-A200. Retain this
guide for future reference.

This Hi-Fi product has been tested to ensure that its operation
will not be adversely affected by normal background levels of R.F.I.
(Radio Frequency Interference). It is possible that if the unit is sub-
jected to abnormally high levels of R.F.I. the unit may not perform as
expected. In the unlikely event of this happening please contact
Musical Fidelity's service department.
Do not remove any covers, the X-A200 will not be covered
under warranty if it has been tampered with. There are no adjust-
ments within. Please refer all service work to an authorised Musical
Fidelity agent.
Connections
All connections should be made before the mains lead is plugged in
and the unit switched on.
The X-A200 is a mono power amplifier, two are supplied for stereo
operation, further units can be used if required for multi channel surround
sound systems or for bi-amping etc.
The X-A200 can be used with a preamplifier or any line level
source which has a volume control. We highly recommend the
matching X-PRE or 'Nu-Vista' Class A Tube Preamps available from
Musical Fidelity as an excellent choice.
Connect your pre-amp or other line level source to the phono input
on the back panel marked "Line Input". For the best results we recom-
mend that you use Musical Fidelity X-LINX "no-nonsense" interconnect
cables for this connection.
Connect your loudspeaker to the loudspeaker terminals situated
on the back panel marked "Loudspeaker Output"
Once these connections are made, plug in the IEC type mains
lead and switch on the unit.
Bi-Amping
The X-A200 has a "Loop Out" facility to allow for easy bi-amping of
speakers with bi-wireable crossovers. In this kind of set-up typically one
X-A200 is used to drive the tweeter (high frequencies) and one to drive
the woofer (low frequencies) of each loudspeaker enclosure. Thus in this
example four X-A200s would be required for a stereo pair.
Taking the left channel connections first, the pre-amp's (or other
source's) left output is first connected to the first X-A200's line input
and then that X-A200's loop output is connected to the second
X-A200's line input, both X-A200s will now be driven from the same
left channel signal. The first X-A200 can now be used to drive the
woofer and the second, the tweeter of the left channel loudspeaker.
Repeat this process for the right channel.
If you are in any doubt about bi-amping, please contact your
dealer who will be able to help and advise you.
