Using your power amplifi er

P35 Power Amplifi er: Front panel

POWER button

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

When you switch your amplifi er on, the light glows amber for a few seconds, during which time the

speakers are disconnected. The light changes to green when the amplifi er is ready for use. A red light

means the amplifi er is in stand-by mode.

The power light may fl ash if a fault has occurred, with the colour of the fl 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 amplifi er is too hot). Ensure that your

amplifi 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 amplifi 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 amplifi er has shut itself down, you should unplug the amplifi er and leave it

for a few minutes before reconnecting. If the fault cannot be cleared in this way,

unplug your amplifi 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 amplifi er. An indicator light shows which set of

speakers are currently selected.

Note that if both lights are out then the amplifi er will appear not to work, as all speakers are switched

off.

A "DC offset fault" is not an

amplifi er fault, but a speaker

protection mechanism. If the

amplifi 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 fi re).

Your Arcam amplifi 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.
