AC mains fuse is blown | Classe Audio CA-M400 specification

ENGLISH

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 use 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 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 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 one or more Channel LEDs are 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.
