5. Problem: No Sound
Indication:
On LEDs not lit
Signal LEDs not lit
Check AC plug.
Confirm that AC outlet works by plugging in another device.
Indication:
On LEDs lit
Signal LEDs not lit
Clip LEDs not lit
Make sure the signal source is operating and eventually try another cable.
Check the position of the volume pots and the position of the gain selec-
tor
Indication:
Signal LEDs responding to signal level
Output Current LEDs are not lit
Check the speaker wiring for breaks.
Try another speaker and cable.
Indication:
Signal LEDs show red (Protect Mode)
Overheating will cause protective muting. Check for proper ventilation. If
the fans are not running the amplifier requires servicing.
Persistent DC at the outputs will force the amplifier in protect mode and
shut down the power supply.
Try to mute or disconnect the signal source and restart the amplifier (i. e.
switch off the amplifier, wait until all indicator LEDs extinguish and switch
the amplifier on again).
NOTE: For other LED indications than described above or if the problem persists
please unplug the amplifier from the mains supply and refer to your authorised
CAMCO dealer/distributor or repair workshop.
5.2 Problem: Distorted Sound
Indication:
Output Current LEDs are lit
Signal LEDs responding to signal level
Clip LEDs not lit
A faulty speaker or a loose connection could cause this. Check the wiring
and try another speaker.
The signal source might be clipping. Keep the Q-POWER amplifiers volume
pots at least halfway up so that the source does not have to be overdriven.
Keep the Q-POWER amplifiers volume pots at least halfway up and try
changing input sensitivity from ,4 V to 32 dB or 26 dB with the gain selec-
tor on the rear.
Indication:
Output Current LEDs are lit
Signal LEDs responding to signal level
Clip LEDs lit
The amplifier is overdriven by the signal source. Reduce the input signal
level
