Question

I simply want to apply effects to my aux mixes

Answer 1

Select the mix you want.

Make sure you can see the faders that say FX Return.

Push up the ones you want to send to that mix.

Answer 2

Hi,

I have only the Series lll rack unit, so I can tell you how to do it using UC SURFACE on an iPad.

When selecting your Aux Channel, swipe all the way to your RIGHT and you will see the faders for the FX.  This is we here to adjust the FX output to the Aux.

Hope this helps
