Positioning the unit

Place your amplifier on a level, firm 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 flow through the ventilation slots.

Connecting to loudspeakers

The red and black terminals on the back of the amplifiers 4 are used to make the connections to the loudspeakers. You can connect one or two pairs of loudspeakers to your amplifier, provided each pair is rated between 8–16Ω. (If one or both pairs have an impedance of less than 8Ω, the combined load on the amplifier falls below 4Ω and could cause an overload.) The pair designated ‘speaker 1’ (SP1) are connected to the lower set of terminals, while the pair designated ‘speaker 2’ (SP2) are connected to the upper set of terminals. To connect one pair of loudspeakers, use the SP1 terminals.

When connecting the speaker terminals of the amplifier with the terminals on the speakers, make sure that like polarities are matched (i.e., match ‘+’ with ‘+’ (usually red) and ‘–’ with ‘–’ (usually black)). Mismatching of polarities will result in a weak central sound, unclear orientation of the instruments and the sense of direction of the stereo being impaired.

There are two options for connecting the speaker cable to the amplifier:

Using bare wire ended leads:

1.Strip back the insulation on the wire to reveal about 2cm of conductor (the metal inside the cable).

2.If the conductor is stranded, twist the strands together tightly to avoid loose strands making contact with the adjacent terminals or the back panel.

3.Loosen the terminal by turning it anti-clockwise

4.Insert the twisted wire through the hole in the terminal.

5.Tighten by turning clockwise.

When making connections with stranded bare ended wires, take great care that no individual strands of wire come into contact with the adjacent terminals or with the back panel. If this should happen, it will cause a short circuit on the output of the amplifier and could damage the amplifier.

Wiring your loudspeakers

Using spade terminals:

1.Loosen the terminal by turning it anti-clockwise

2.Insert the spade connecter under the terminal.

3.Tighten by turning clockwise.

Connecting to a power supply

Wrong plug?

Check that the plug supplied with the unit fits your supply and that your mains supply voltage agrees with the voltage setting (115V or 230V) indicated on the rear panel of the unit 2 before plugging in.

If your mains supply voltage or mains plug is different, consult your Arcam dealer or Arcam Customer Support on +44 (0)1223 203200.

The product must be earthed.

Mains lead

The appliance is normally supplied with a moulded mains plug already fitted to the lead. If for any reason the plug needs to be removed, it must be disposed of immediately and securely, as it is a potential shock hazard when inserted into the mains socket. Should you require a new mains lead, contact your Arcam dealer.

Plugging in

Push the plug (IEC line socket) of the power cable supplied with the unit into the socket (POWER INLET) 1 in the back of the unit. Make sure it is pushed in firmly.

Put the plug on the other end of the cable into your power supply socket and switch the socket on.
