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.
