how do you control how much of each input gets sent to each output? Obviously the faders will control it for all outputs, but how do you change it for a specific one?
You need to select the mix you want to control using the blue mix select buttons on the lower right hand corner of the mixer.
When you select a mix the channel faders will reposition and become that mixes send level control. They are then what was the “aux knob” on an analog mixer.
To go back the main mix control either tap the selected mix button again to toggle back to the LR main mix or just hit the blue LR button above the master fader.
