Thanks for the input Swany and Jon.
Swany as Jon said leaving the mics down isn't an option as far as I am concerned. My/our objective is to make our singers sound as good as we can. For some singers that means turning up the mic amplification to pick up those who don't project as well as others. This usually isn't a problem until the singer is one with a high suprano voice. Those are the ones who will get the feedback really going. So with that said...
Jon I would really be interested in the outcome of your Driverack PA install and whether it helps eliminate the feedback. Not sure I could swing a $500 piece of equipment but hopefully can get something a little less expensive.
