I just sent Chris Church a pm with this same question, but I'll put it out here on the board too in case I don't hear from him in time. This weekend I was going to use my new CAFS omni's with my R-09 and battery box, but just read on a thread in the retail section that my battery box will damage the mics as it 12 volt. My question is when running these mics directly in to the R-09, should I go mic-in or line in? Thanks for any help or advice.
