500-capacity house of worship — touring-grade headroom

Worship is the application where the audio brief most often outruns the assumed budget. A 500-capacity room with a contemporary music programme is functionally a small venue — 90 dB at the listener with full-band music, not 70 dB of BGM and a wireless lapel.

This preset configures the planner for a 30 × 18 m hall, an 18 m furthest-listener distance and a 50 % power setting on the K-array Mugello KH5 touring element. The Mugello family carries the SPL headroom for the application; you can swap to the smaller KH3 if the venue is closer to 300 cap, or step up to a true touring rig if the room serves regular concert events.

What to read from the output: SPL at listener (target 90 dB; the planner will flag a shortfall as a power increase or box count change), coverage radius (use to determine how far apart left / right hangs need to be from the stage centreline), and quantity (line-array elements come as 2-box left/right minimum; the math reports the planner's rectangular-area approximation, not the final hang).

What is out of scope: subwoofer count and crossover (a separate calculation against the music programme low-frequency content), delays for under-balcony fills, and the structural rigging assessment without which no line-array is ever hung over a congregation.
