There’s a lot that can go wrong with a  PA System. Here’s a few tips for the ‘big stuff’. Those things that we’re afraid of, that make loud noises and scare us to death. Not all problems are that way, some are just little annoying things; annoying enough to disturb a church service. Here’s a few of the most common symptoms of PA Problems;

  • The speakers or monitors produce an annoying humming sound
    • Grounding problems are usually manifested by a hum in the speakers.
  • There’s a constant “shhhhhhhhhhhh” sound in the speakers
    • This is known as white noise, and is normal. If it is unusually loud, then try adjusting the input levels of mixer channels. Volume controls on speakers might be too high.
  • When I try to get volume, squeaks and squawks occur
    • This is called feedback and it’s caused by speakers feeding the audio signal back into a microphone. Speaker and Monitor placement may be incorrect. Make sure all mics face away from speakers and that the main house speakers are forward of all mics. Monitors are on the floor speaking toward the platform, but should never be aimed into mics, or bouncing off walls and into mics.
    • Check your mic input levels
  • Sometimes I hear snaps, crackles or pops
    • Check the system and instrument cables for breakage, damage or looseness.
  • The speakers sound gritty
    • This is called distortion. Lower the output level to the speaker from the amp, and check all other levels in your equipment.
