No Power
•
Make sure that the cabinet is plugged in.
•
The internal Breaker automatically protects the cabinet in case of bad working.
No Sound
•
Check that the mixer, sound source and processor is sending signal to the unit.
•
Check that the cable from the mixer, sound source or processor to the units is
correctly connected. Replace the cable if defective.
•
Make sure the output volume (gain) control on the mixing console and processor is
sufficiently turned up to drive the inputs of the speakers.
•
Make sure the mixer and the processor do not have a Mute on.
Distorted sound
•
The system is overloaded and has reached maximum power. Turn down the mixer's
output or the channel's gain.
.
Poor bass performance
•
Check the polarity of the connections between the mixer/processor and the
MAW-
218/D
amplifier. If you have inverted any of the Pins (1,2 or 3) in one of the extremes
of the wire, the losses may be extremely high.
Noise and Hum
•
Make sure all connections to the active units are in good conditions.
•
Avoid routing the signal cables near AC cables, power transformers, or EMI-
inducing devices.
•
Check if there is any light dimmer on the same AC circuit as the cabinet. Connect
the sound system to a different phase than the lights.
Overvoltage LED (on RED)
•
Check that the input voltage is within the right values (230V +/- 10%)
