4. The AC mains fuse is blown.
Th ere is a specifi c troubleshooting procedure for a blown AC mains fuse,
since this rare occurrence sometimes indicates a signifi cant problem. Please
use the following steps, in order:
a. Disconnect your amplifi 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 (specifi ed below). Using any other type
of fuse, particularly a larger-value fuse, can result in permanent
damage to your amplifi er.
If you are not comfortable replacing the
fuse yourself, contact your Classé dealer for assistance.
Mains voltage: 100/120VAC
Fuse type: MDA slow-blow
Rating: 10A
Mains voltage: 230/240VAC
Fuse type: MDL slow-blow
Rating: 8A
c. After replacing the fuse and fuse cover, reconnect the amplifi 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 fi ne, place the amplifi er back into standby
and carefully reconnect the input cable and power the amplifi er
up. If the fuse then blows (or the amplifi er goes into protection),
you may have a serious fault with your preamplifi er/processor.
Contact your Classé dealer.
e. Finally, if everything is still fi ne, place the amplifi er in standby
and carefully reconnect the speaker wires. Check both ends of
the speaker wires for possible short circuits. Th en power up the
amplifi er again. If the amplifi er remains functional (the fuse
does not blow), then the original fuse probably blew in order to
protect the amplifi er from a large AC mains surge. If it blows
again, contact your Classé dealer for assistance.
5. The Standby LED is flashing quickly.
• Try resetting the unit by disconnecting it from the AC mains
power, waiting a few seconds, and reconnecting the amplifi er to
power. If this does not solve the problem, contact your Classé
dealer for assistance.
