Creek Audio A43, Operating Instructions

Page: 1 / 2

Thank you for purchasing the A43 Power amplifier. You are now in possession of a State of
the Art Power Amplifier. The functions and operation of the A43 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 supply in the country of use. The IEC socket
end of the cable should be firmly inserted into the connec-
tor 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: T 2 Amp surge resisting for 220-
240V 50Hz AC, T 4 Amp surge resisting for 110-120V
60Hz AC, T 6.3 A surge residing for 100V (Japan).

N.B. Radio interference.
The A43 is designed to work properly in normal domestic operating conditions.
However, the amplifier’s performance may be seriously affected if sited near to, or in the
room with, a working radio transmitter such as a mobile phone or CB radio, etc. Re-sit-
ing the A43, or the radio, will normalise the situation. If in doubt consult your dealer.
