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 preamplifi er is not in mute mode. is 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 amplifi er 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 preamplifi er.
• If the problem occurs with all inputs, check the cables between
the preamplifi er and the power amplifi er. 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 preamplifi er is plugged into the AC mains and
switched on, and that the AC mains are operating normally. e
unit will automatically attempt to protect itself from improper
AC mains voltages by not powering up. Make sure your power
amplifi er is off (if the amplifi er is already connected to the
preamp) before plugging your preamplifi er into the AC mains
and powering it up.
• If your preamplifi er was plugged in properly, try the following:
put it in standby, switch off the main power switch in the back,
and unplug the unit for at least thirty seconds before trying to
power it up again. (Sometimes a brownout of short-term loss of
power might require a restart.)
Important! Make sure to power down your power amplifier BEFORE
doing the restart.
