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.
Constant noise, buzzing and/or humming
Possible cause
Faulty electronic
Poor low-frequency output
Possible cause
Improper polarity
Action
Any constant noise originates in the amplifier, 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.
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 cables to be sure
they are all identically wired and connected. Check the line signal cables to be sure they
are all correctly wired.
