LX-LPS Dual Input Phono Stage

Instruction Manual

Introduction

Thank you for purchasing the LX-LPS. We
sincerely hope that it will bring you many years
of outstanding listening pleasure.

Installation Precautions

Your new LX-LPS is designed and built to
provide trouble-free performance, but as with all
electronic devices, it is necessary to observe a
few precautions:

Do not use the LX-LPS near water. The unit must
not be exposed to dripping or splashing and no

objects lled with liquids, such as vases, must

be placed on the unit.

Keep the LX-LPS away from heat such as
radiators. No naked flame sources, such as
lighted candles, should be placed on the unit.

Power Supply Note:

Only use approved Musical Fidelity DC power
supply. The use of other adaptors or supplies
could seriously damage the LX-LPS.

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 LX-LPS yourself, as
this will invalidate the guarantee.

Place all connecting cables where they are not
likely to be walked on or trapped by items placed
on them.

The LX-LPS will operate in accordance with its

specications within the following environmental

range:

• Temperature 5 to 45 degrees Celsius

• Humidity 10 to 90% non condensing

There are no user adjustments inside. Please
refer all service work to an authorised Musical
Fidelity agent.

Connections

All connections must be made before the mains

adaptor is plugged in, and before any amplier

connected is switched on. Always switch off

the equipment attached to the LX-LPS before

connecting/disconnecting power, changing
leads or inputs.

Inputs

Using good quality RCA leads (not supplied),

connect the left and right turntable outputs to
the correct LX-LPS INPUT sockets.

Use the phono MM input for moving magnet

cartridges. Fit your loading plugs if required.

Use the phono MC input for moving coil

cartridges. Fit your loading plugs if required.

Outputs

Connect the LX-LPS left and right OUTPUTS to
the desired LINE LEVEL (e.g. AUX) inputs of the

amplier system.

Power

Plug the DC connector lead from the power
supply unit into the LX-LPS power inlet socket,
and plug the adaptor into a convenient wall
mains outlet. Switch on the unit, and the status

LED next to the power switch will light to conrm

the unit is ready for use. Now select the MM/MC
input to match.

Earthing

An earth terminal is provided. Optimum earthing
arrangements differ according to setup

Connect earth wire from turntable to this
terminal if hum is apparent.

Any particular setup may work perfectly or even
better if this terminal is left disconnected and
there is no harm in doing so.

Use

Turn the volume on amplier to normal listening

levels, sit back and enjoy the music.

This product has been designed so that it may

be left on indenitely, but please note that the

mains adapter may become warm to the touch

- this is normal.

Loading plugs

The standard values as supplied (Green plugs
for MC, Blue plugs for MM) can be used for
the majority of today’s cartridges or custom
values can be tted to match your preference.

equipment. Always check the most obvious possible causes rst, such as the following examples:
