•  If the hum exists only on the phono input, make sure 

the turntable/tonearm assembly is not too close to other 
components. Th

  ere should be at least 12 inches (30cm) clearance 

from the other components. Th

  e more clearance you provide, the 

better (as long as the tonearm cable is not stretching).

•  Make sure the tonearm cable is not touching or running 

alongside an AC cable.

•  Make sure you have the proper loading for your phono cartridge. 

If you are in doubt, consult your authorized Classé dealer.

• Th

  is symptom suggests you have electrical noise on your AC 

mains line. Try connecting to another AC circuit (not merely a 
diff erent plug, but a diff erent circuit).

•  Check to see if you have any halogen lighting or dimmers on the 

same circuit as the integrated amplifi er, as they can be the cause 
of hum in power supply transformers.

•  You may need to adjust the input off set setting to compensate 

for diff erences in output level between source components. 
Alternatively, the input off set setting may have been adjusted 
inappropriately. Either way, you can correct the problem by 
going to the following location in the menu system:

Menu • system setup • input • input name • off set

where input name is the input you feel needs to be adjusted.

•  If the input that seems incorrect is the phono input, make sure 

you are using the proper gain setting for the type of cartridge you 
are using. If in doubt, consult with your authorized Classé dealer.

Th

  ere is a specifi c troubleshooting procedure for a blown AC mains fuse, 

since this rare occurrence sometime indicates a signifi cant problem. Please 
carefully follow steps “a” through “e”, in order:

a.  Disconnect your integrated amplifi er 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.
