Here's the deal. 6 piece band, 3 vocal mics. We need a new PA. Looking at spending <$2000. Found some speakers I like: Yamaha BR15 Speakers x 2 Yamaha BR12 Monitors x 2 This chews up about a grand once you add speaker stands. That leaves me with a grand to spend.... I need advice on mixer and power amp OR powered mixers. Any suggestions to help narrow it down in my price range?
