So, if I'm running in to the XLRs, and out optically to a JB3, the only knobs I need to concern myself with are the sensitivity knobs for each channel, right? The way I'm reading the manual, it makes it sound like the "output" and "volume" knobs only affect the master output jacks, which it says are the RCA and phone jacks (and not the optical).
Do I have this right?
