Hello, I am looking into purchasing a PA and I am wondering if anyone would be kind enough to give me a few suggestions? -I need it to be loud enough for the vocals to be heard clearly over the rest of my band when we practice (two guitars, bass, drums, hard rock-room is about 15x15) -While I need sheer volume for practice, I also need quality and clarity because I will be using it for solo shows (acoustic guitar and vocals only) at smaller venues -Need at least 4 channels -Need some sort of monitor for the solo shows -Price range is probably around $700, but maybe this isn't possible for what I'm looking for, or on the other hand, maybe I don't need to spend that much? I have a Korg D32XD digital recorder which I am thinking about using as a mixer, and then just buying a power amp... but I am not sure I want to lug that big (and expensive) of a thing to shows, so maybe I would be better off not using it. Anyone ever tried something similar? Any advice is greatly appreciated!! Thanks!
