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.

Signal/noise ratio (CCIR)
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.
