Sorry to cont. with the drama here, but should Channel 1 be considerably hotter than channel 2? I was able to recreate the power/volume drop while playing the piano through channel 2 and changed to the channel 1, just panned over with the trims both set a twelve o'clock and got a tremendous volume boost, like 10db or better. Is that normal, we've never really tried that much with channel 1, but you had mentioned in an earlier post that running the mic that I had running through one of the stereo channels, into channel one and getting the benefit of a preamp, I was thinking that may be the reason for the boost. The SM 58's and 57's don't really require a preamp but this seemed to be a great difference. Is this normal?
