I am curious if there is a way to rout an input channel fader, and aux fader (of the same channel) to a rotory knob?
I would like to be able to control the volume of my background music via rotory knob, but also have it control the same channel of my aux fed subs. As of right now, I have to adjust the volume of both highs and lows separately.
Set the AUX to POST FADER for that channel, and it will follow the main mix fader setting. Generally aux fed subs should all be set to POST anyway so that they track the main mix. This allows you to set the differences using the aux mix, but once set those relations stay the same as the main fader levels are changed.
