4. The AC mains fuse is blown.
ere is a specic troubleshooting procedure for a blown AC mains fuse,
since this rare occurrence sometimes indicates a signicant problem. Please
use the following steps, in order:
a. Disconnect your amplier from the AC mains, as well as from its
input connections and speaker connections, and remove the fuse
cover on the rear of the unit.
b. If the fuse appears to be blown, replace it only with a fuse of
the same type and rating (specied below). Using any other type
of fuse, particularly a larger-value fuse, can result in permanent
damage to your amplier. If you are not comfortable replacing the
fuse yourself, contact your Classé dealer for assistance.
Mains voltage: 100-120VAC
Fuse type:
IEC time lag, high breaking capacity
Rating: 12A 250V
Mains voltage: 220-240VAC
Fuse type:
IEC time lag, enhanced breaking capacity
Rating: 6.3A 250V
c. After replacing the fuse and fuse cover, reconnect the amplier to
the AC mains only and turn it on without reconnecting either the
inputs or the speaker wires. If the fuse blows again, disconnect it
from the AC mains and contact your Classé dealer for assistance.
d. If everything seems ne, place the amplier back into standby
and carefully reconnect the input cable and power the amplier
up. If the fuse then blows (or the amplier goes into protection),
you may have a serious fault with your preamplier/processor.
Contact your Classé dealer.
e. Finally, if everything is still ne, place the amplier in standby
and carefully reconnect the speaker wires. Check both ends of
the speaker wires for possible short circuits. en power up the
amplier again. If the amplier remains functional (the fuse
does not blow), then the original fuse probably blew in order to
protect the amplier from a large AC mains surge. If it blows
again, contact your Classé dealer for assistance.
5. The Standby LED is flashing quickly.

power, waiting a few seconds, and reconnecting the amplier to
power. If this does not solve the problem, contact your Classé
dealer for assistance.
