Commercial Audio: Three Ways Sound Systems Go Wrong
KSEDCO installs distributed audio and multimedia systems for Georgia businesses — restaurants and retail across metro Atlanta, hotel and event space in Savannah, corporate common areas, fitness facilities, worship spaces. Most of the systems we are called in to fix failed in one of three predictable ways.
1. Too few speakers, turned up too far
A ceiling speaker covers a circle whose diameter depends on ceiling height and the speaker’s coverage angle. Space them to a budget instead of to the geometry and you get hot spots directly under each speaker and dead zones between them, and the only way to make the dead zones audible is to make the hot spots unpleasant. Getting the spacing right means overlapping coverage at ear height, not at the ceiling. It costs more in speakers and far less in complaints. In tall spaces — a converted warehouse dining room, a gym, a hangar-style venue — pendant speakers hung down into the room beat ceiling speakers fighting a 24-foot deck.
2. One zone doing four jobs
A dining room, a patio, a bar, and back-of-house do not want the same source at the same level, and a single amplifier channel cannot give them that. Zones get separated at design time, with independent level control and source selection, and the amplifier and 70-volt tap loading set so one zone can be turned up without robbing another. The patio is almost always the zone that gets left out of the original design and then retrofitted badly.
3. No processing between the source and the speakers
Feedback in a room with open microphones, boominess in a hard-surfaced space, and a system that sounds fine at open and unusable at a full house are all DSP problems. Equalization, limiting, and — in rooms that fill and empty through the day — ambient noise compensation belong in a processor that is set once and locked, not in whatever knobs happen to be reachable from behind the bar.
Outdoor audio in Georgia
Covered patios, pool decks, and courtyards are outdoor installations even under a roof. Georgia humidity gets into anything that is not sealed, so speakers need weather-rated enclosures and grilles that will not rust out in a season, terminations need to be made so water drains away from the connection, and the run has to come back to an amplifier in a protected location. On the coastal plain around Savannah and Brunswick, salt exposure and hurricane-season wind loading push us toward stainless hardware and mounting into structure rather than into trim. Summer lightning is the other factor: outdoor speaker runs and the amplifiers behind them get surge protection and a proper ground.
Multimedia and control
Where audio is one part of a larger package — displays, projection, microphones, streaming — sources, switching, and control get designed together instead of accumulating. The rack goes in a ventilated, lockable location on clean power, every channel and zone gets labeled, and staff get a control interface exposing only the functions they should be touching. A rack behind a manager’s desk with unlabeled dials gets set correctly once and never again.
Turnover
- Speaker layout with model, tap setting, and zone for every device
- Amplifier channel loading and rack elevation
- The commissioned DSP configuration file and a record of the settings
- Zone and source naming that matches how staff actually describe the space
- A walkthrough with the people who open and close the building, not just the manager who signed the order
