Greetings! We are in need of live wireless vocal mics. We have a group that sings two-three times a week at our church and they normally have six or seven vocalists. Right now they drag cables across the stage and things get bunched up, not to mention some of our microphones are on their last legs. So, we would like to look into a multi-channel solution, possibly an 8 channel wireless system. Does anyone have any recommendations? We are totally sure about budget, but we have talked about possibly spending around $500 / microphone. I look forward to hearing from you! Thanks!
