I often see tapers having used SP-CMC-8 + SP-SPSB-11 + EdirolR-09HR to record concerts which is a set up that I have but for whatever reason doesn't work for me due to distortion. It's mainly the drums that cause the distortion on the recordings that I have made. I know that the battery box is plugged into the line in input not the mic input so wondered if the settings on the back, especially Mic Gain make a difference or maybe Low Cut or Limiter. Any advice would be welcome as anyone with the same set up will know that a few quid has been used on this gear
