Eric,

If there's any low cut switches on the recorder or on the mics, then
disable them as that can sometimes cause problems.  Is there any auto-
overload setting on the recorder?  Disable that as well.  -6dB is
supposed to be the max for digital recording, rather than 0dB, so you
could try an even lower setting (e.g. max -20dB), then boost volume
in post and see if you still get distortion.
