Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into
account all current national, federal, state, and local laws and regulations. It is the
responsibility of the installer to ensure all loudspeakers are safely installed in accordance
with all such requirements. When loudspeakers are suspended, Electro-Voice strongly
recommends the system be inspected at least once per year or as laws and regulations
require. If any sign of weakness or damage is detected, remedial action should be taken
immediately. The user is responsible for making sure the wall, ceiling, or structure is capable
of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker
not associated with Electro-Voice is the responsibility of others.
Warning!
Do not suspend this product in any other manner than explicitly described in this manual, or
Electro-Voice installation guides. Suspending any object (loudspeaker) is potentially
dangerous and should only be done by individuals with thorough knowledge of techniques,
materials, and regulations for suspending objects overhead. Electro-Voice loudspeakers can
only be suspended using accessories and hardware described in Electro-Voice manuals and
installation guides. Do NOT use handles to suspend the loudspeaker. Handles on Electro-
Voice loudspeakers are intended to only be used for temporary transport by people. Items,

Troubleshooting
amplifier outputs. If there is no sound, verify all the
electronics are on, the signal routing is correct, the
source is active; the volume is turned up, etc.
Correct/repair/replace as necessary. If there is sound,
the problem is wiring.
Wiring Verify you have connected the correct cables to the
amplifier. Play something at a low level through the
amplifier. Connect the test loudspeaker in parallel with
the malfunctioning line. If the sound level is gone or is
very weak, the line has a short in it (possibly a severe
scrape, pinch, or a missed connection). Using the test
loudspeaker, move down the line and test each
connection/junction until you find the problem and
correct it. Observe proper polarity.

5. No sound produced

Faulty connection Check all connections at amplifier and loudspeakers to
ensure they are all clean and tight. If the problem
persists, check the wiring. See problem 1.

If noise is present, but no program material is playing,
evaluate each component as necessary to isolate the
problem. Most likely there is a break in the signal path.
Check and correct the system grounding, as required.
Slowly increase the input gain knob level to engage the
microphone pre-amp.
Use a dynamic microphone that does not require
phantom power. If using a microphone requiring
phantom power, an external phantom power source is
needed
Slowly increase the input gain knob level to engage the
microphone pre-amp.

Verify level controls of the source are properly structured
by using the VU meter indicator on the LCD screen. If the
VU meter bar is solid or the system indicates LIMIT, the
input or source level is too high.
Reduce the microphone levels at the mixing console or
input source. If the microphone is connected directly to
the speaker, reduce the input level on the speaker.
Positioning the microphone close to the sound source
increases gain-before-feedback. See problem 6.
Change the MODE to LIVE or SPEECH.
Whenever possible setup the loudspeakers so the
microphone is behind them. If using the loudspeaker in a
monitor position, aim the loudspeaker to the back of the
microphone.
Press and hold the MASTER VOL knob for 5 seconds.
If these suggestions do not solve your problems, contact your nearest Electro-Voice dealer or
Electro-Voice distributor.
