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 difficulties or problems as the suspected problem speaker, use the information below to isolate
the problem.
No output
Possible cause
Speaker cables
Amplifier
Intermittent
Possible cause
Poor connections
Constant noise, buzzing and/or humming
Possible cause
Faulty electronic
device in the signal
chain
Poor low-frequency output
Possible cause
Improper polarity

Action
Reseat all connectors
Substitute known good speaker cables
Check solder joins
Tighten set-screws on the banana connectors or 4-p connectors
Inspect cable for damage
Inspect wire or connector for stray strand that may short
Make sure the amplifier channel is being fed a signal. Most amps have a
"signal input" LED to indicate the presence of a signal. Re-patch the speaker
to an amplifier channel that is known to work.
Action
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. Tighten the set-screws on the banana connectors or 4-p
connectors.
Action
Any constant noise originates in the amplifier, mixer, signal processing, source
devices, or line-level wiring. Check and correct system grounding as required.
check for noisy sources or electronic components. Check wiring for shielding.
Action
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.
