plug instrument outputs into the mic XLR input jacks
with phantom power on, unless you are certain it is safe
to do so.

main mix.
The first two stereo channels [9/10 and 11/12 on the
ProFX16 and 15/16 and 17/18 on the ProFX22] are
hybrid channels, each with a mic input XLR jack [5]
and low cut switch [10]. In these channels, the gain
control [9] only affects the mic input. The stereo line
inputs are fixed at unity gain.
