How Do I Design a PA System That Is Loud, Clear and Even?
Quick answer

A good PA is designed, not just installed. Measure the area and the background noise, choose speaker type (ceiling, wall, column or horn), place speakers for even coverage, group them into zones, size amplifier power with at least 20% headroom and use a 100V line for long cable runs. Test speech clarity at the farthest points before handover.
