Question

When a stereo input (aux/in) is added to an aux mix, is there a way to control which channel (L/R) is routed to the mix?

Answer 1

Create a stereo linked Aux. Panning for an AUX in done in Aux mix as suppose to the main mix.

Answer 2

Answering my own question, you create two auxes and stereo link them to form a stereo aux. After you add a channel to a stereo aux, you can pan it left/right.
