Troubleshooting

In general, you should refer any service problems to your Classé dealer. Before
contacting your dealer, check to see if the problem is listed here. If it is, try the
suggested solutions. If none of these solves the problem, contact your Classé
dealer.

1. Everything appears to be on, but there is no sound.

• Adjust the volume control to a moderate level (one that should

be audible but is not excessive).

• Make sure the source component for which the input has been

selected is switched on and is out of its standby mode.

• Make sure the proper input has been selected for the source

being used.

• Check that the preampliﬁer is not in

mute mode. This is

indicated by the operational menu icon in the form of a speaker
with a bar through it. Press Mute to disengage.

• Ensure that the power ampliﬁer is powered up and out of standby

mode.

• Check if the tape monitor is enabled. If it is engaged and the

recorder is off, you will not hear the selected source. Disengage
by pressing Tape, unless you wish to monitor the recording.

• If the problem occurs only with a particular input, check the

interconnect cables between that source and the preampliﬁer.

• If the problem occurs with all inputs, check the cables between

the preampliﬁer and the power ampliﬁer. If no fault is found
there, check the speaker wires for secure connections.

Important!

Check that the power ampliﬁer is off before checking any

connections between the preampliﬁer and power ampliﬁer,

or between the power ampliﬁer and the speakers.

2. There is no sound and the Standby LED is not lit.

• Ensure the preampliﬁer is plugged into the AC mains and

switched on, and that the AC mains are operating normally. The
unit will automatically attempt to protect itself from improper
AC mains voltages by not powering up. Make sure your power
ampliﬁer is off (if the ampliﬁer is already connected to the
preamp) before plugging your preampliﬁer into the AC mains
and powering it up.
