So today had been the usuall controlled chaos of a load in. Now, I'm a freshan and the senior TD is graduating and I'm next in line. So this was my first time "in charge" of a load in although it was a small show and it was only me and a good friend. So I come back to the church at 5:00, show starts, act 1 goes fine, then in act 2 there is a song that has two soloists and I have there mic #'s written down and I unmute them as the pick the mics up. Now we usually use our venue's board but the church had nothing so we brought our own. And this board of ours has no mute lights so you have to just look and see which ones are up. Well, somehow, right before this song I get all confused and mute the solo mics and unmute every other mic sitting on the floor. Then I get confused as to why I'm not getting sound and I start bumping stuff up. Then I get crazy feedback and I kill everything uber fast, It took me a good 30 seconds to figure out what I had done and fix it, DOH! Oh yeah, and we're buying a new board, and it will have mute lights.
