You know Gav, that is a good idea….
Why do any switching….
The speakers will already be switching with speaker 2 giving his mic to speaker 3 while speaker one 1 speaks into a mic that goes to the room (ambient).
Wonder if that could be a problem with a speaker wearing a wireless while speaking into a regular mic that goes to the entire room/audience???
But I think I will do your idea. Less equip.
thanks,
Al
