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.
