What is relay and delay systems in auditorium acoustic design?
You are right. Relay designs automatically disable nearby speakers when a microphone is being used, which helps prevent microphonics and other feedback distortions. Sound takes time to travel, and in auditoriums misleads listeners as to the direction from which the sound is coming, in particular it doesn’t appear to come from the speaker. Designing delayed loudspeaker outputs with correctly increased sound levels maintains the sound image direction from the speaker, not the loudspeakers. There’s a lot of information about this on the web, and one simple overview is at: http://www.rane.com/note140.
