OPERATING INSTRUCTIONS FOR THE CREEK A42

Thank you for purchasing the A42 Power amplifier. You are now in possession of a State of the Art Power

Amplifier. The functions and operation of the A42 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 connector on the rear panel marked

"Mains Input". Remember, do not overload the mains wall socket with too many plugs or adapters. 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 2Amp surge resisting for 220-240V

50Hz AC, T 4Amp surge resisting for 110-120V 60Hz AC.

The loudspeakers should be connected using a suitable pair of cables designed specifically for audio use.

These should be fitted with dedicated 4mm plugs which can be screwed, but are preferably soldered, onto

the cables. Please consult your dealer for advice if you are unsure. It is very important to connect the

loudspeakers to the loudspeaker sockets in the correct phase. That is to say that the positive and negative

sides of the cable are connected to the loudspeaker in the same way on each channel. If it is connected out

of phase a severe loss of bass performance and a spreading of the stereo image will result.

It is

recommended not to use loudspeakers of less than 4Ω resistance or more than two pairs of 8Ω speakers

running from the amplifier at one time. However, bi-wiring of one pair of speakers, using the four sockets,

can improve the sound of your system (consult your dealer for more details). It doesn't matter which output

sockets (LS1 or LS 2) are used on the back of the amplifier as they are both connected to one source in the

amplifier.

If the amplifier is to be used in a Bridged Mono (balanced) configuration, a P42 pre-amplifier with the

appropriate driver board and a further A42 amplifier will be required. Each amplifier should be wired to drive

one loudspeaker only (left or right). The major difference in the wiring of a balanced system is that the

loudspeakers are not connected to ground. The loudspeaker wires should be connected between the live

connections of the left and right outputs of LS1 or LS2 on the rear of the amplifier. Phasing of the leads is

still important and therefore if the positive (marked) wire is connected to the bottom connector on one

channel (Right) it should be wired the same connector on the other channel. Bi-Wiring is still possible, but it

is not advisable to connect more than one 8Ω speaker to a Bridged (balanced) A42 at a time as it will

overheat and could possibly damage the amplifier. Do not connect the negative loudspeaker wire to any

ground connector or the bridging mode will be defeated.

N.B. It is very important not to short the loudspeaker cables together when the other ends are still

connected to the amplifier otherwise permanent damage can result. If it is necessary to move or

change the location of your loudspeakers, make sure that you switch off the amplifier from the mains

first.
