Howdy! First post! Drama teacher with a show in tech (100 middle schoolers!!!) on Monday, just found our QSC Powerlight 1.0 (1000W) amp in Protect Mode. No sound coming thru to speakers, board picking up fine... Are we up a tree or a creek? How would I figure out if another amp that is a 500W amp would work with our system? Where do I begin fixing this mess? Thanks for any and all help.
