Introduction
Thank you for purchasing the X-LPS Version 3 stereo phono pre-amplifier.
We sincerely hope that by allowing the very best from your record collection, it
will bring you many years of listening pleasure.
Installation Precautions
Your new X-LPS V3 is designed and built to provide trouble-free performance, but
as with all electronic devices it is necessary to observe a few precautions.
nDo not use the X-LPS V3 near water. The unit must not be exposed to
dripping or splashing, and no objects filled with liquids, such as vases,
must be placed on the top.
nKeep the X-LPS V3 away from heat sources such as radiators.
nOnly use the mains adaptor provided.
Use of other power supplies could seriously damage your X-LPS V3.
nPlace all connecting cables where they are not likely to be walked on or
trapped by items placed on them.
This Hi-Fi product has been tested to ensure that its operation is not adversely
affected by normal background levels of Radio Frequency Interference (R.F.I.),
and that it does not itself generate excessive amounts of interference.
However, if a problem persists, please contact your Musical Fidelity agent.
Never open the case of the X-LPS V3 yourself, as this will invalidate the guaran-
tee. There are no user adjustments inside.
Please refer all service work to an authorised Musical Fidelity agent.
IMPORTANT NOTE
To avoid unwanted noise, always ensure that the volume control on your amplifier
is at minimum when turning the X-LPS V3 power supply on or off.
Connections
All connections should be made before the accessory mains adapter is
plugged into a mains outlet.
The X-LPS V3 is easy to connect into your system. If the turntable is fitted
with a moving magnet type cartridge, plug the RCA/phono leads from your
turntable into the X-LPS V3 inputs marked MM. If the turntable is fitted
with a moving coil type cartridge, plug the leads into the inputs marked MC
instead. Now select the appropriate cartridge type with the MM/MC selector
push button on the X-LPS V3 rear panel. This button should be "in" for MC
and "out" for MM.
Using good quality RCA/phono interconnect lead, connect the Left and
Right Outputs from the X-LPS V3 to unused line level inputs (e.g. Auxiliary,
Line etc.) on your amplifier system:
If your turntable has a separate, single, chassis earth wire (sometimes includ-
ed with the RCA/phono leads), this should be connected to the green earth
terminal on the rear of the X-LPS V3 (marked with the earth symbol).
Connect the low voltage AC output lead from the accessory mains adaptor to
the X-LPS V3, and then plug the mains adaptor into a convenient supply out-
let. Switch on mains power and ensure that the blue LED indicator on the
X-LPS V3 is lit.
Select the appropriate input on your amplifier, and adjust the volume control
as required.
The X-LPS V3 has been designed so that it may be left on indefinitely, but
please note that the mains adaptor may become warm to the touch - this is
normal.
