4. The AC mains fuse is blown.
There is a specific troubleshooting procedure for a blown AC mains fuse,
since this rare occurrence sometimes indicates a significant problem. Please
follow the following steps, in order:
a. Disconnect your amplifier 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 (specified below). Using any other type
of fuse, particularly a larger-value fuse, can result in permanent
damage to your amplifier. If you are uncomfortable replacing the
fuse yourself, contact your Classé dealer for assistance.
Mains voltage: 100/120VAC
Fuse type: MDA slo-blow
Rating: 12A
Mains voltage: 230/240VAC
Fuse type: MDA slo-blow
Rating: 10A
c. After replacing the fuse and fuse cover, reconnect the amplifier 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 fine, place the amplifier back into standby
and carefully reconnect the input cable and power the amplifier
up. If the fuse then blows (or the amplifier goes into protection),
you may have a serious fault with your preamplifier/processor.
Contact your Classé dealer.
e. Finally, if everything is still fine, place the amplifier in standby
and carefully reconnect the speaker wires. Check both ends of
the speaker wires for possible short circuits. Then power up the
amplifier again. If the amplifier remains functional (the fuse
does not blow), then the original fuse probably blew in order to
protect the amplifier from a large AC mains surge. If it blows
again, contact your Classé dealer for assistance.
5. The Standby LED is flashing quickly, and a Channel LED is flashing
red.
• Try resetting the unit by disconnecting it from the AC mains
power, waiting a few seconds, and reconnecting the amplifier to
power. If this does not solve the problem, contact your Classé
dealer for assistance.
