5.4 Maintenance
Your EAW loudspeaker normally requires no regular maintenance for normal use. However, you
can do several things to keep your loudspeaker in good operating and cosmetic condition.
1. Testing: Periodically test your loudspeaker for proper performance. A simple test is to
play a CD through it using well-defined, articulate, wide-range program material.
Listen to ensure all drivers are working properly and for any evidence of distortion or
other extraneous sounds. Test at several volume levels: very low, normal and high.
2. Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected for
security, wear, deformation, corrosion, and any other circumstances that may affect the
load handling capability.
3. Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt”.
Dust, food spills or similar can usually be removed with a cloth dampened with water
or a mild household cleaner. Avoid using any strong solvents as this may damage the
finish.
4. Scratches or Dents: Minor scratches on the enclosure can be painted over with an
outdoor latex paint or simply colored in with a “Sharpie” or artist’s marking pen. More
serious gouges or dents
should be sanded out, filled with wood putty and repainted.
Black touch-up paint in pints (part #
810050) or quarts (part #810049) is available
from the EAW Service Department. Tips for repainting are on EAW’s website:

Section 6 Troubleshooting
Loudspeaker difficulties usually fall into one of the following categories. The causes for each
problem are listed in the most likely order of probability.
6.1 No Sound or Low Output
1. Loudspeaker cables or connectors are mis-wired or faulty. Check all cabling. Refer to
these instructions for correct loudspeaker cable connections. The best way to check a
suspect cable is to swap it with a known good cable. Read the loudspeaker’s input
panel to verify correct cable connections.
2. Electronic equipment is not turned on or 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.
3. 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 Service for appropriate
troubleshooting.
6.2 Distorted Sound
1. The power amplifier is clipping. The signal level is exceeding the limits of your
system and you must reduce the level.
2. Other electronic equipment is clipping. Ensure that no equipment in the signal chain
is being overdriven. For example: input(s) or summing bus in the mixing console,
equalizers, etc.
3. Driver(s) not working properly. Contact EAW Service for appropriate troubleshooting.
