EVID design & installation FAQ
All FAQ
Why aren't my EVID speakers producing sound?
Check the amplifier connection with a known-good test speaker, verify the wiring pairs and polarity, and — if a subwoofer is used — confirm the subwoofer input-panel wiring is correct.
Why do my EVID speakers have poor low-frequency response?
When two speakers are connected out of polarity (out of phase), the low frequencies cancel each other acoustically. Improperly wired subwoofer panels that reverse the amplifier connections cause the same effect.
Why do my EVID speakers have intermittent output such as crackling or distortion?
Check all connections at the amplifier and speakers to ensure they are clean and tight.
Why do my EVID speakers have constant noise such as buzzing, hissing or humming?
This is usually caused by a defective amplifier, or by poor system grounding / a ground loop.
