I'll check the next time I fire mine up, but I would think that the L/R pan on a paired Aux should be independent of the L/R of L/R but not independent of the individual channel pans. (Especially when running post fader.) As I read your complaint, the pan of the L/R output channel controls the sound on the paired Aux out. Mine only gets fired up about once a week right now, so it might be a few days before i can test it. Did you try pre-fader and pre-dsp?
