Common audio issues in restaurants and how AV techs fix them
The audio problems restaurants run into most often, from feedback and dead zones to clipping and background music that is too loud.

Restaurant audio has to do several jobs at once. It should play background music softly, carry announcements when needed and never make a conversation at the next table harder. Most problems come from a handful of causes.
Speakers placed too close together
When speakers overlap in coverage, some tables get a loud wall of sound while others hear almost nothing. A technician will usually re-aim or re-space the speakers and set each zone to a sensible level.
Feedback from microphones
Feedback is often caused by a microphone pointed at a speaker or placed too close to a loudspeaker. Adjusting gain, moving the microphone and adding a simple limiter usually solves it.
Clipping and distortion
When an amplifier or source is driven too hard, the sound turns harsh. The fix is usually to lower the input level at the source, check the amplifier gain structure and make sure the speakers are rated for the power they receive.
Background music that is never quite right
- Set a maximum volume so staff cannot push it too high
- Use separate zones for the bar, dining area and kitchen where possible
- Test the system at real service volume, not during a quiet afternoon
A good technician will walk the room during a busy period, listen from different seats and adjust the system until it works for guests and staff alike.
