Introduction

Thank you for purchasing the LX2-HPA. We
sincerely hope that it will bring you many years
of outstanding listening pleasure.

Installation Precautions

Your new LX2-HPA 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 LX2-HPA 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 LX2-HPA 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 LX2-HPA.

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 LX2-HPA 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 LX2-HPA 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 LX2-HPA before

connecting/disconnecting power, changing
leads or inputs. This is to prevent loud noises
being put out through the headphones.

Inputs

Using good quality RCA leads (not supplied),

connect the left and right outputs from a CD
player or other audio source to the LX2-HPA
INPUT sockets.

Outputs

Two headphone sockets are available to allow
a greater range of headphones to be used
without need of adaptors. the 3.5mm Jack is
standard for 3.5mm terminated phones. The
1/4 inch (6.3mm) jack is standard for 1/4 inch
terminated headphones.

Connect the LX2-HPA 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 LX2-HPA 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.

Enhanced power supply (sold seperately)
For optimum performace you can connect the
Musical Fidelity enhanced power supply (EPS).
When connected the EPS LED will light to

conrm that both units are ready for use.

Use

You can adjust the gain by +6dB or -6dB
according to listening preference and headphone
impedance.

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.

Turn the volume on the amplifier to normal
listening levels, sit back and enjoy the music.
