So basically the manual that came with the mixer has a typo mistake cause I just read it again and it says "-30 dBu and -50 dBu are both microphone-level settings. It is suggested to start with the -30 dBu settings and if your microphone seems to have too much gain (volume) try the -50 dBu position."
Condensor mic outputs can be in the -30 dBu range, although some are lower. Dynamic mics are typically in the -50 dBu range.
