DONT EVER LET JUNIOR TECHIES NEAR A SOUND DESK. during one of our colleges performances, a smallish one. the TD decided it was time to train up some of the less well trained techies. i have no problem with THIS, but after spending a day showing them the basics of sound and mixing, nothing complicated we let them loose. one of them decided to listen to some of his music coz he was bored so, he had his laptop plugged in and plugged the headphones in, played it and he sat there listening to it, not realising it was being blasted out over the P.A aswell! not good! and he ddint realise for a good ten minutes. unitl i ran up to the box and turned it off. not good at all.
