No Power
•
Make sure that the cabinet is plugged in.
•
The Fuse is blown. Replace the fuse on fuse holder with one of the same type. This
replacement must be done by specialized people as the fuse is set inside the amplification
modules. AC Voltage may be controlled by rotating the Fuse 90º (230V or 115V).
See fuse
holder for more information.
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
MA-206
amplifiers. 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.
