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.
Possible cause
No output
Cables
Intermittent
Poor connections
Constant noise, buzzing and/or humming
Faulty electronic
device in the signal
Poor low-frequency output
Improper polarity

Action
Reseat all connectors

Inspect cable for damage
Inspect wire or connector for stray strand that may short
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.
Any constant noise originates in the amplifier, mixer, signal processing, source
devices, or line-level wiring. Check and correct system grounding as required. chain
check for noisy sources or electronic components. Check wiring for shielding.
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.
