7. TROUBLESHOOTING

Loudspeaker difficulties usually fall into one of the following categories. The causes for each are listed in the most likely order of probability.

No Sound or Low Output

•Loudspeaker cables or connectors are not wired correctly or are faulty. Check all cabling, referring to these instructions for the correct connections. The best way to check a suspect cable is to swap it with a known good cable. Check the loudspeaker’s input panel to verify correct cable connections.

•Electronic equipment is not turned on, or the level controls are not adjusted properly. Make sure that all equipment in the signal path is powered up, and that all controls are set to appropriate levels for normal operation.

•Loudspeaker is not working. Connect the loudspeaker cable to a known good loudspeaker, leaving all equipment set to the same levels. If the problem disappears, the loudspeaker is probably not working. Contact EAW Commercial Technical Support for appropriate troubleshooting.

Distorted Sound

•The power amplifier is clipping. The signal level is exceeding the limits of your system and you must reduce the level.

•Other electronic equipment is being overdriven. Ensure that no equipment in the signal chain is being over driven. For example: input(s) or summing bus in the mixing console, equalizers, etc.

•Driver(s) not working properly. Contact EAW Commercial Technical Support for appropriate troubleshooting.

Partial Sound (frequency band missing)

•Incorrect EQ settings in the electronic equipment. Ensure that all EQ settings and filters on the mixing console, preamplifier, or other equipment are set for normal operation. Ensure that level controls on electronic crossovers and associated amplifiers are correctly set, and that all cables and connections for such equipment are connected and working properly.

•Driver not working properly. Contact EAW Commercial Technical Support for appropriate troubleshooting.

•The crossover network inside the loudspeaker is not working properly. Contact EAW Commercial Technical Support for appropriate troubleshooting.
