Pre-Fader and Post-Fader Auxiliary Sends
Normally, effect sends are post-fader, so the signal sent to the effect follows the program level in the mix. Occasionally you may wish to feed an effect from a pre-fader source so that the signal level from the aux control is independent of the channel fader position. Aux sends are selectable pre- or post-fader globally (all Aux 1’s for instance) from the Mix Options screen in the Setup window, or individually on a channel -by-channel basis either from the channel strip or the Fat Channel.
In the channel strip, Alt-click the Aux Send level indicator to toggle between pre-and post-fader operation. Post-fader is indicated by a red bar, pre-fader is indicated by a yellow bar.
In the Fat Channel, clicking on the PRE buttons below the Aux knobs toggles between pre- and post-fader operation. Yellow indicates pre-fader, otherwise the aux is post-fader.
