Here is are the specs.

The ProFX Series’ flagship model, the 22-channel ProFX22 prominently features 16 clean microphone preamps with insert points on the first 10 channels; inline channel compression for four inputs (channels 11-14); Mackie’s RMFX 32-bit mono in/stereo out digital effects processor; a seven-band graphic EQ with well-chosen frequency points (125, 250, 500, 1k, 2k, 4k and 8k Hz, +/-15dB), switchable between Main Mix and Monitor 1 outputs; stereo/dual mono USB I/O (subgroups 1/2 or main L/R via USB to your DAW of choice); and lovely-sounding three-band EQ with sweepable midrange (mono channels).

Approximately 25” long by 16” deep, the ProFX22 is compact and lightweight enough (18 lbs.) to very easily carry under your arm, yet large enough to easily and comfortably mix mains and monitors with just enough crowd- and band-pleasing effects and channel compression, ultimately satisfying the requirements for small- to medium-sized venue gigs in a most professional manner.
