3. Only one speaker seems to be playing.
• Check the main balance control setting of the CP-700 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.
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-700.
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.
