TROUBLESHOOTING
One certain method of determining if a speaker is faulty is to substitute a
speaker that is known to work correctly for the suspected problem speaker.
If the “normally correct speaker” is experiencing the same diiculties or
problems as the suspected problem speaker, use the information below to
isolate the problem.
Error Possible cause Check
No output Cables Reset all connectors
Substitute known good cables Check
solder joins
Inspect cable for damage
Inspect wire or connector for stray
strand that may short
Intermittent Poor connections While it is possible for a faulty
speaker to exhibit intermittent output,
it’s more likely that an output cable/
connector is the problem. Check the
soldering on your connectors
Constant noise,
buzzing and/or
humming
Faulty electronic
device in the signal
Any constant noise originates in the
amplier, mixer, signal processing,
source device in the signal devices, or
line-level wiring. Check and correct
system grounding as required.
Chain check for noisy sources or
electronic components. Check wiring
for shielding.
Poor low-frequency
output
Improper polarity When two speakers in close proximity
to each other are connected
out-of-polarity, they can partially
cancel each other out, especially
at low frequencies. Check your
speaker cables to be sure they are
all identically wired and connected.
Check the balanced line signal cables
to be sure they are all correctly wired.
