Classe Audio CP-500 - V2.4 Owner's Manual page 33

3. Only one speaker seems to be playing.
• Check the main balance control setting of the CP-500 by pressing the Menu
button, followed by the balance button (or simply press Bal on the remote
control).
• Does the problem occur with all inputs? If so, check the interconnect cables
between the preamp and the power amp. If no fault is found there, check the
speaker wires for secure connections.
Important! Be certain that the power amplifier is off before checking any
connections between the preamplifier and power amplifier, or
between the speakers and the power amplifier.
• If the problem occurs only with a particular input, check the input balance
control setting of that particular input:
Menu ➝ system setup ➝ input ➝ input name ➝ balance
where input name is the particular input in question.
• If the input balance appears to be correct, check the interconnect cables
between the corresponding source component and the CP-500.
4. The IR remote control seems not to function.
• Ensure that there are no obstacles between the IR remote and the IR sensor
(located to the right of the Mute button).
• If the batteries are weak, replace them with fresh ones.
5. There is a hum coming out of the speakers.
• If you are running single-ended interconnects, make sure they are not
running alongside any AC power cords.
• If you are running single-ended interconnects, make sure they are not too
long. Long runs of single-ended interconnects have a natural tendency to pick
up noise even if they are shielded.
• If any source components connected to your preamplifier has a cable TV
hooked up to it, try disconnecting the cable television line from the source. If
the hum goes away, you will need an isolation device between your cable and
that particular source. Refer to your Classé dealer for one of these inexpensive
devices.
• If you have the optional phono module in your preamplifier, make sure that
the ground wire of the tonearm is secured properly to the ground lug on the
back of your preamp.
• If the hum exists only on the phono input, make sure the turntable/tonearm
assembly is not too close to other components. There should be at least 12
inches (30cm) clearance from the other components. The 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.
