POWER INLET

115/230V

Positioning the unit

Place your amplifi er on a level, fi rm surface.

Avoid placing the unit in direct sunlight or near sources of heat or damp.

Ensure adequate ventilation. Do not place the unit in an enclosed space such as a bookcase or

cabinet as both of these will impede air-fl ow through the unit.

Connecting to other equipment

The connections on the rear of the C31 fall into four groups:

1. dedicated audio inputs;

2. recording loops;

3. connections for power-amplifi ers;

4. remote control and trigger connections.

These groups are described below.

General advice on connecting to other equipment

We recommend the use of high-quality interconnect cables to and from your amplifi er to ensure the

best sound quality; cheap 'bell-wire' interconnects may seem to be a good alternative, but they will

reduce the overall quality of your system, and are a false economy.

Make sure that audio and power cables are kept as far apart from each other as possible. This

reduces the risk of 'noise' from the power cables bleeding into those for audio.

Cables should be kept as short as is practical.

For each of the audio inputs/outputs that you wish to use, connect the terminal labelled

Similarly, the terminal labelled

the C31.

Conventionally, stereo-phono leads have plugs that are coloured red for the right channel and white

or black for the left channel, to aid channel identifi cation.

Audio inputs

DVD – This input is intended for use with a DVD-player. Connect the stereo audio outputs of your

DVD player to these sockets.

AV – This input is intended for use with general audio-visual equipment, such as a VCR,

digital TV/satellite receiver, or Nicam tuner. Connect the analogue audio outputs of the

device to this input.

TUNER – Intended for use with a radio tuner.

CD – Intended for use with a CD-player.

AUX – As with the 'AV' input, this is intended for general use. Connect the audio outputs of

any unit with a line-level output (tape deck, tuner, etc.), to this input.

PHONO (if fi tted) – As standard, no phono input is fi tted to the C31.

Phono inputs are provided on a separate plug-in module which your Arcam dealer or

distributor can supply and fi t. This module is compatible with most high-output moving-coil

and moving-magnet cartridges (MM) and low-output moving-coil cartridges (MC). Once the module

is fi tted, MM or MC is selected via the

Why is this useful?

The phono module (or an external phono amplifi er) is required if you wish to connect a record

player to the C31. This is because the low-voltage output of a record player requires a pre-

amplifi cation stage before the signal can be used.

If you have already an external phono amplifi er that you wish to use, connect this to one of the

line-level inputs, such as the 'AV' input.
