COUPLED
(Top LED illumnated):
Use when the loudspeaker is coupled to a surface such as the stage floor as a
performer monitor or when mounted on a wall or the ceiling.
Use when arrayed with other JF
NT
/KF
NT
loudspeakers to attenuate excess energy caused by
mutual coupling.
Use when room acoustics are "live," meaning with higher reverberation times, to
improve intelligibility by reducing the amount of LF reverberant energy excited by the
loudspeaker.
MONITOR
(bottom LED illumnated):
Use when the loudspeaker is used as a Stage Monitor to increase gain before feedback.

M a i n t e n a n c e
Your EAW loudspeaker may require little to no regular attention for normal use. However,
performing regular inspections and maintenance can ensure your loudspeaker remains in
optimum operating and cosmetic condition. Refer to the “EAW Loudspeaker Manual” for
periodic inspection and maintenance recommendations and procedures

loudspeaker components are field replaceable. These include the drivers and
amplifier module. All other service and repair information must be obtained by contacting the EAW
Service Department or the service department of the EAW Distributor for your country. See the
“EAW Loudspeaker Manual” for contact information. This applies to both warranty and non-
warranty faults.
8.2.1
AC MAINS FUSE
CAUTION:
To maintain safety
approval certifications, use a fuse that
meets the specific time delay, pulse
current capability/melting integral (I2t
/ A2s), and breaking capability listed.
DANGER:
Note and be sure to replace the fuse in the same physical orientation as when it
was removed. Double check the circuit board labeling to ensure the orientation is correct for
the proper AC mains input voltage. Failure to follow this warning could result in the
incorrect voltage being applied to the loudspeaker. IF 230 V IS APPLIED TO A 115 V
LOUDSPEAKER, IMMEDIATE AND CATASTROPHIC DAMAGE TO THE
LOUDSPEAKER WILL RESULT AND MAY CAUSE A FIRE HAZARD, SERIOUS
PERSONAL INJURY, OR DEATH.
