Service information

Before returning your amplifier for service, please check the following:

Sound cuts out for no reason

If the temperature of the internal heatsink rises above a safe level, then a thermal cutout inside the amplifier will operate.

The power indicator on the front panel flashes and the protection system temporarily removes the power to the speakers. The system resets itself as the heatsink cools down.

With two pairs of low impedance speakers connected, overloads are more likely. Overloading the amplifier may cause it to shut down because of overheating.

Note that because of the high output voltage from a CD player, it is possible to drive the A90 at full power even though the volume is not set at maximum.

Amplifier does not switch back on

The A90 and P90 amplifiers have a protection mechanism which is activated if you switch the unit on immediately after turning it off. If this mechanism activates, wait 30 seconds then try again.
