Thank you for purchasing the A52 Power amplifier. You are now in possession of a State of the
Art Power Amplifier. The functions and operation of the A52 are extremely simple. However, the
following notes are provided to explain all aspects of its design and use.
MAINS CONNECTION
When unpacking the amplifier please keep the packing material
in a safe place for possible future use. In the pack there is a
separate mains cable suitable for connecting to the mains sup-
ply in the country of use. The IEC socket end of the cable
should be firmly inserted into the connector on the rear panel
marked "Mains Input".
Remember, do not overload the mains wall socket with too
many plugs or adaptors. The high quality performance of the
amplifier will be impaired if the electrical supply to it is in poor
condition. If in doubt, consult a qualified electrician or your
dealer. The "Mains Input" connection is also fitted with a fuse,
specifically suited to the supply voltage of the country of use.
The correct value is clearly marked on the rear panel next to
the Mains Input.
Should it be necessary to replace the fuse, ensure that you use
the same type as specified on the rear panel. i.e.
5 x 20mm cartridge type T4 Amp surge resisting for 220-
240V 50Hz AC, T8 Amp surge resisting for 110-120V 60Hz
AC, T10 Amp surge resisting for 100V 60Hz.

CONNECTING THE LOUDSPEAKERS
The loudspeakers should be connected using suitable cables
designed specifically for audio use. These should be terminated
with dedicated spade lugs. Alternatively, twisted bare wire, prefer-

N.B.
The A52 is designed to work properly in normal domestic operating conditions. However,
the amplifiers performance may be seriously affected if sited near to, or in the room with, a
radio transmitter such as a mobile phone or CB radio rig, etc. Re-siting the A52, or the radio,
will normalise the situation.
