9. TROUBLESHOOTING
No power
 Check the device is connected to mains
 Check mains cable is in good condition.
 The thermal fuse may be activated. The replacement of this fuse must be carried
out by specialized personnel as it is an internal component of the amplifier module.
No sound
 Check with the indicators that the signal is being sent from the mixer.
 Check that the signal cables are in good condition and connected at both ends
 The mixer output level must not be at minimum.
 Check that the mixer in not in Mute mode.
Distorted output signal
 The system is being saturated with a very high input signal, frequently caused by
the same mixer. Check the output level or mixer gain channels.
Poor bass levels
 Check the polarity on the signal connections between the mixer and cabinets. If
any of the Pins (1, 2 or 3) have been inverted at the cable ends, this will cause
significant performance and sound quality loss.
Noise and Hum
 Check that all the connections to the active units are in good condition.
 Avoid intertwining between mains supply cables or proximity to transformers or
Electromagnetic (EMI) emitting devices.
 Check there is no light intensity regulator in the same AC circuit as the unit.
ALWAYS connect the sound and light circuits in different phases.
Overvoltage LED light (RED)
 Check that the mains voltage is within the limits (230+/-10%)
