4. The AC mains fuse is blown.
ere is a specic troubleshooting procedure for a blown AC mains fuse,
since this rare occurrence sometimes indicates a signicant problem. Please
use the following steps, in order:
a. Disconnect your amplier 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 (specied below). Using any other type
of fuse, particularly a larger-value fuse, can result in permanent
damage to your amplier. 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, high breaking capacity
Rating: 6.3A 250V
c. After replacing the fuse and fuse cover, reconnect the amplier 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 amplier back into standby
and carefully reconnect the input cable and power the amplier
up. If the fuse then blows (or the amplier goes into protection),
you may have a serious fault with your preamplier/processor.
Contact your Classé dealer.
e. Finally, if everything is still ne, place the amplier in standby
and carefully reconnect the speaker wires. Check both ends of
the speaker wires for possible short circuits. en power up the
amplier again. If the amplier remains functional (the fuse
does not blow), then the original fuse probably blew in order to
protect the amplier from a large AC mains surge. If it blows
again, contact your Classé dealer for assistance.
5. The Standby LED is flashing quickly.

power. If this does not solve the problem, contact your Classé
dealer for assistance.
