I have multiple sources going to my desk monitors. The Behringer just gives me control over switching between what goes to the monitors and singular volume control. Anyway, the playback settings are the first thing I checked, and everything looks good there. I also ran the analog outs from the UX2 directly into my desk monitors and the output is just as low (even with the output knob cranked). There is no problem passing signal, its just a very low output volume coming from the UX2 analog outs.
