Service information
Continual improvement policy
Arcam has a policy of continual improvement for its products.
This means that designs and specications are subject to
change without notice.
NOTE: All specication values are typical unless otherwise
stated.
Before returning your amplier 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 amplier will operate.
The power indicator on the front panel ashes 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 amplier 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.
Amplier does not switch back on
The A90 and P90 ampliers 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.
