POWER button
Switches the unit on and off. The light indicates the status of the ampli er.
When you switch your ampli er on, the light glows amber for a few seconds, during which time the
speakers are disconnected. The light changes to green when the ampli er is ready for use. A red light
means the ampli er is in stand-by mode.
The power light may ash if a fault has occurred, with the colour of the ashing light indicating the
nature of the fault:
<
green – a D.C. offset fault has occured (see info. box);
<
amber – a thermal fault has occured (the ampli er is too hot). Ensure that your
ampli er has adequate ventillation;
<
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 ampli er
the unit waits for six seconds before checking to see if the fault has cleared. If
the fault clears within six seconds, 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 ampli er has shut itself down, you should unplug the ampli er and leave it
for a few minutes before reconnecting. If the fault cannot be cleared in this way,
unplug your ampli er and contact your Arcam dealer.
SP1 and SP2 (P35 only)
These buttons allow you to select and deselect the main (SP1) and secondary (SP2)
sets of speakers attached to your ampli er. An indicator light shows which set of
speakers are currently selected.
Note that if both lights are out then the ampli er will appear not to work, as all speakers are switched
off.
A “DC offset fault” is not an
ampli er fault, but a speaker
protection mechanism. If the
ampli er is supplied with a DC
voltage (rather than the expected
AC voltage) for an extended length
of time, the coils in the attached
speakers will eventually burn out
(or, in extreme cases, catch re).
Your Arcam ampli er can detect this
condition, and cut the current to the
speakers.
DC offset faults can occur
intermittently in all set-ups,
particularly if a tuner or satellite
receiver is connected. If it occurs
frequently or predictably, please
contact your dealer for advice.
