Propagation Delay Calculator

Enter the distance between two points — the main PA and a delay speaker, or FOH and the stage — and this converts it to milliseconds of propagation delay at the speed of sound (343 m/s, 20°C). Use the result as your starting delay time when time-aligning delay towers or fills to the main hang; fine-tune from there by ear or with a measurement tool once the system's live.
