10 Troubleshooting
10.1 Passive loudspeakers
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.
Sources not
connected
Check all cables between the source and the
loudspeaker with a multimeter or cable tester. Replace
any suspect cables with a known good cable.
2. Poor Low-
Frequency
Response
Loudspeakers wired
out-of-polarity
When two loudspeakers are connected out of polarity,
the low frequencies will cancel each other acoustically.
Carefully observe the wire markings or tracers on your
loudspeaker wires. Verify the amplifier (+) terminal is
connected to pin 1+ of the NL4 connector and the
amplifier (-) terminal is connected to pin 1-of the NL4
connector.
3. Intermittent output
such as cracking or
distortion
Faulty connection Check all connections at amplifier and loudspeaker to
ensure they are all clean and tight. If the problem
persists, check the wiring. See problem 1.
4. Constant noise
such as buzzing,
hissing or humming
Defective source or
other electronic
device
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.
Poor system
grounding or ground
loop
Check and correct the system grounding, as required.
5. Microphone
produces acoustic
feedback when
INPUTLEVEL is
amplified
Microphone position
is too close to the
front of the
loudspeaker
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.
If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or Electro-
Voice distributor.
