On LEDs not lit
Signal LEDs not lit
Check AC plug.
Confi rm 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 amplifi er requires servicing.
Persistend DC at the outputs will force the amplifi er in protect mode and
shut down the power supply.
Try to mute or disconnect the signal source and restart the amplifi er (i. e.
switch off the amplifi er, wait until all indicator LEDs extinguish and switch
the amplifi er on again).

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 amplifi ers volume
pots at least halfway up so that the source does not have to be overdriven.
Keep the Q-POWER amplifi ers volume pots at least halfway up and try
changing input sensitivity from 1,4 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 amplifi er is overdriven by the signal source. Reduce the input signal
level
