POWER

English

POWER (and power indicator light)

Switches the unit on and off. The light indicates the status of the amplifier.

When you switch your amplifier on, the light glows amber for a few seconds, during which time the speakers are disconnected. The light changes to green when the amplifier is ready for use. A red light means the amplifier is in standby mode.

The power light may flash if a fault has occurred, with the colour of the flashing light indicating the nature of the fault:

green – a D.C. offset fault has occured

amber – a thermal fault has occured (the amplifier is too hot)

red – a short circuit fault has occured (this can happen if the speaker cables are not connected correctly and are making contact with each other or with the chassis)

red and amber – more than one fault has occured. Except for a thermal fault, if one of the above faults is detected by your amplifier the unit waits for six seconds before checking to see if the fault has cleared. If the fault clears within six seconds, then the unit continues operation; otherwise the unit shuts itself down. In the case of a thermal fault, the unit waits until its sensor temperature lowers before resuming operation.

If the amplifier has shut itself down, you should unplug the amplifier and leave it for a few minutes before reconnecting. If the fault cannot be cleared, unplug your amplifier and contact your Arcam dealer.

SP1 and SP2

These buttons allow you to select and deselect the main

(SP1) and secondary (SP2) sets of speakers attached to your amplifier. An indicator light shows which set of speakers are currently selected.

NOTE: If both lights are out the amplifier will appear not to work, as all speakers are switched off.
