Thank you for the info - I found a way that made a big difference with one of my wireless mics. I was always using the XLR out to the TRS input of line 2 or the XLR input of line 1.

I found that by going from the unbalanced 1/4" output of the wireless receiver to the 1/4 input (NOT TRS cable, but TS cable). That the input sensitivity was reduced greatly and I am now able to use my wireless mic without distortion and can put the input at about 1/2 (5 out of 10) instead of .5 out of 10.
