Test tone at +4 dBu (pro level) with all front panel gain knobs all the way down
input 1 on XLR and TRS, line in setting, LOW, mixer 100 = -33
input 2 same = -34
input 3 TS>mini, LOW, mixer 100 = -6
input 4 same = -6
So it's a lot more sensitive.
I plan on running my preamp TS to mini into 3/4 and using the 1/2 for SBDs or another set of mics when the opportunity arises. Most of the patches I get offered are XLR (sometimes TRS) anyway.
