Our aud has FM Transceivers. The ones that aren't broken work remarkably well except - whenever you go backstage you get blasted with static. Static, static static! It's enough to drive you insane. But if someone talks over the radio it comes in find. But as soon as they finish, static again. I suspect the
dimmer pack...
Our board has contracted a sound tech available for any purpose really. He has a hard-wired comm system, sure you have to run the cables for it but itt's a ton better than the whole friggen crew fighting over the few headsets we have. But in most cases, the
TD's turn it down. Only during the show when they hear nothing but static do they realize their error. Oh well.
