I record a lot of live recitals (jazz and classical), and I usually use 2 SM57's for room mics. I know these aren't a very good choice in recording this kind of situation. The problem I get with these is that since I use the 57's as room mics and the inputs have to be turned way up to get a good signal, I get a lot of hissing on my recordings. Can anyone recommend any good room mics for this kind of situation in the $400-500 price range? I just want to get a good, well rounded sound and a signal that won't hiss or buzz. Thanks.
