4. The amplifier keeps shutting off.
• Make sure you are providing adequate ventilation to the
amplifier, and that the ambient room temperature is below
105°F (40°C).
• Run through the troubleshooting sequence outlined
above (assuming the amplifier is going into its protection
mode).
5. 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 signifi-
cant problem. Please use the following steps, in order:
a. Disconnect your amplifier from the AC mains , as well as
from its input connections and speaker connections. Re-
move the
fuse cover at 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 uncomfort-
able replacing the fuse yourself, contact your Classé dealer
for assistance.
Mains voltage: 100/120VAC
Fuse type: MDA slow-blow
Rating: 15A
Mains voltage: 230/240VAC
Fuse type: MDA slow-blow
Rating: 12A
c. After replacing the fuse and fuse cover, reconnect the am-
plifier to the AC mains only and turn it on without recon-
necting 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 re-
mains functional (the fuse does not blow), then the origi-
nal 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.
