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 / Action: 
Speaker cables, Reseat all connectors, Inspect cable for damage, Inspect wire or connector for stray strand 
that may short 

Intermittent 

Possible cause / Action: 
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. Reseat all connectors 

Constant noise, buzzing and/or humming 

Possible cause / 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.
