First set step gain was at the lowest setting (+10), trim at 0, so +10 altogether, with a -20db attenuator to the recorder. Was peaking on the recorder around -21 db. Second set turned the trim all the way down, so zero gain altogether, but took the attenuator off (and moved the mics back to the very edge of the stage a couple feet back from where they were first set). Was peaking on the recorder around -9 db.
Got the first set done last night and doesn't seem to be distorted not distorted, I mean clipped, though honestly I don't really know what I'm listening for.
