5. Set up

The mains lead supplied with this prod-

uct has an IEC mains plug end which

fits into the IEC socket located on the

rear panel. The other end is fitted

with an appropriate mains plug of your

country. In the UK this is the stan-

dard UK13A plug.

The performance of this pre-amplifier

will be impaired if the electrical supply

is in poor condition. We recommend

that you use a high quality wall socket

directly, or a multi-way socket unit

designed for audio use. You may also

wish to try a combined multi-socket

and power supply conditioner designed

for audio to optimize fidelity.

We recommend that you place the

pre-amplifier on a suitable rack, table

or platform support, offering maxi-

mum isolation from mechanical vibra-

tion.

We recommend that the pre-amplifier

is turned on half an hour or more

before use. Most audio electronics

sound better once they have 'warmed

up'. We do not recommend that you

leave it on all the time but it will come

to no harm if you do. From new, you

will find that the pre-amplifier will need

about 100 initial hours use to achieve

its optimum audiophile sound.

All RCA (phono) input and output sock-

ets are mounted on the rear panel

and are of quality construction.

recommend that you use high-quality

signal cables for optimum perform-

ance. The MP3 input and headphone

outputs are described in Section 6.

Two pairs of RCA output sockets allow

you to bi-amp from the pre-amplifier if

you wish.
