Insert is post-HPF, pre-EQ and operates at 0dBu. Aux sends 1 and 2 are pre-fader. Aux sends 3 and 4 are post-fader. Aux outs on 1/4" impedance balanced at 0dBu.
The "rec out" RCA jacks carry the main L-R mix (pre-fader, post L-R insert). The "Alt out" RCA jacks carry the signal as selected by the "Alt Out" switches (L-R pre-fader, L-R post-fader, or monitor) and the "Alt out" level control in the master section.
USB interface allows stereo recording of the mix bus prefader, mix bus past-fader, aux sends 1/2 or aux sends 3/4. USB interface also allows playback via USB (on a dedicated stereo input channel) or loop to/from effects, such as a software reverb on a laptop.
14-channel mixer with 6 mono (mic/line) inputs, 4 stereo (line) inputs, 2 stereo returns, and built-in USB interface for recording. When using all analog inputs at line level, this mixer can handle 6 mono and 6 stereo inputs; or 10 mono and 2 stereo inputs. Each mono input has insert, rolloff, 3-band EQ (12k hi shelf, sweepable 120-4k mid, 80Hz lo shelf), 4 aux sends, pan, mute, pre-fader solo and 100mm fader. Each stereo input has 2-band EQ (12k hi shelf, 80Hz lo shelf), 4 aux sends (2 are switchable as stereo), balance, mute, pre-fader solo and 100mm fader.
