Rigging Problems
Because of the potential serious consequences and liabilities due to faulty rigging, contact
the EAW Service Department to determine the appropriate service solution for any
problems with the rigging hardware integral to the enclosure or EAW rigging accessories.
Enclosure and Integral Hardware
Enclosure problems, such as loose hardware, faulty joints, or other structural problems,
will usually be heard as distinct buzzes, rattles, or other unwanted noises. To test for
enclosure problems, use a sine wave signal manually swept on the loudspeaker. The
input level should be varied, because certain problems can be level as well as frequency
specific. It may be possible to field-repair some enclosure problems.
Cosmetics
While the paint finish and the wood used for the enclosures is of high quality and
durability, scuffs, marks, and other blemishes may appear from normal handling. For paint
touchup, use good quality latex paint. For a more permanent and cosmetically correct appearance,
contact the EAW Service Department for the paint specifications or to purchase small quantities for
touch-up. For cosmetically damaged wood, use common woodworking methods and materials as
appropriate for the damage.
Driver Service
A faulty driver will usually cause readily audible distortions or other unwanted noises. In
other cases, they may stop functioning. Use your ears and test signals or other sound
source to determine which one is at fault. The drivers can be field serviced by replacing the entire
driver or having the driver repaired (such as diaphragm replacement) by a qualified service
technician.
1.
Access the drivers by removing the front grille.
2.
Remove the LF driver or HF horn/driver assembly by unscrewing their retaining screws.
3.
Lift the LF driver or HF horn/driver assembly from the baffle.
4.
Disconnect the signal cable from the driver.
5.
To reinstall or replace the LF driver and/or the HF horn/driver assembly, reverse the above
steps. Make sure that LF drivers are connected with the blue+ and black- signal wires and that
HF drivers are connected with the red+ and black- signal wires.
IMPORTANT:
When reconnecting the signal wires to the driver, connect the colored wire to the
plus (+) terminal and the black wire to the (-) minus terminal.
