Using this handbook Your amplifier may have been installed and set up by an authorised Arcam dealer. In this case, you may wish to go directly to the sections describing the use of this equipment. Safety Safety guidelines are set out on the inside front cover of this handbook. Many of these items are common sense precautions, but for your own safety, and to ensure that you do not damage the unit, we strongly recommend that you read them. Contents Safety guidelines........................................
Installation 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 You can connect one or two pairs of loudspeakers to your amplifier, provided each pair is rated between 8–16Ω.
Standby power For remote standby operation, the amplifier’s control power supply is kept powered up all the time the unit is connected to the mains supply. The front panel power switch powers down all other circuitry. Power consumption in this mode is less than 2.5W. E nglish This means that even though the power switch is off, it may be possible to hear a slight hum coming from the mains transformer inside the amplifier. This is perfectly normal.

Bi-wiring and bi-amping loudspeakers Before you start Bi-amping your system WARNING: Do not make any connections to your amplifier while it is switched on or connected to the mains supply. Before switching on please check all connections thoroughly, making sure bare wires or cables are not touching the amplifier chassis (which could cause short circuits) and you have connected positive (+) to positive and negative (–) to negative.
Service information Sound cuts out unexpectedly E nglish Before returning an amplifier for repair, please check the following: Heatsink protection If the temperature of the internal heatsink rises above a safe level, a thermal cutout inside the amplifier operates, the power indicator on the front panel flashes and the protection system temporarily removes power to the speakers. The system resets after the heatsink has cooled down.
