6 Troubleshooting
Problem Possible Cause(s) Action
1. No sound Amplifier 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 still no
sound, then the problem may be wiring.
Wiring Verify you have connected the correct cables to the
amplifier. Play something at a low level through the
amplifier. Connect a 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.
2. Poor Low-
Frequency
Response
3. Intermittent output
such as cracking or
distortion
4. Constant noise
such as buzzing,
hissing or humming

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.

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.

High amount of

This Bluetooth® enabled loudspeaker occupies the same
operating frequencies as other Bluetooth® devices, as
well as Wi-Fi and other wireless transmissions (like
wireless home phones). If you are experiencing drop-
outs, your speaker may be in an environment that makes
reliable wireless audio difficult. Try to move the
loudspeaker to different locations in the room, and
especially away from 2.4gHz routers and microphone
receivers. If the problem persists, revert back to a wired
connection while at that particular venue.
If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or
Electro-Voice distributor.
