Thanks for some interesting suggestions. Yes lots of automation and panning so phase locked or at least good enough for amplitude panning in neighbouring speakers. I like the wireless idea. We've used wireless boosters on a local network to control control centre with tablet before so the wireless system could be a plus apart from I'd have to program it myself and am too busy. As long as there's not toooooo much desychronisation......Anyone who might want to help with that please pm me . Powers not usually so much of an issue as it doesn't all need to be linked to same source usually. I'm looking for 32 channel solutions .
