5 TROUBLESHOOTING

P. 20

5.1 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 selector

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-POWERamplifiers volume pots at least halfway up so that the source does not have to be overdriven. Keep the Q-POWERamplifiers volume pots at least halfway up and try changing input sensitivity from 1,4 V to 32 dB or 26 dB with the gain selector 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
