Hey everyone. I'm running sound for a stage show (musical) and have some questions about wireless mics. If anyone could help me out some, I would greatly appreciate it! My first concern is feedback. When I start to get feedback, what is the first thing I should do? Cut the bass? I understand what feedback is, but what is the best way to remove feedback DURING a show performance? I'm a little confused with the wireless mic "sensitivity" setting and the wireless receiver "sensitivity" setting. For an example, let's say that a singer is peaking a lot. My best bet would be to turn the sensitivity from -20 to -30, correct? How exactly does that work? And there is also a sensitivity setting on the wireless receivers back in the booth. So if during a number one of the singers is peaking, is there anything I can do from the booth to make it better? If someone can answer some of the questions I would love it! I'm not an expert and I'm running the sound tonight for the show, so any knowledge would be wonderful! Thanks!
