I recently used my Studio 192 on location to record a gig, so I disconnected it from my Eris monitors and Temblor t8 sub. Now that I've reconnected everything back here in the studio, the main volume on the 192 isn't controlling the output volume on the sub. I'm getting sound from the sub, but I can only control the volume from the volume knob on the back of the sub. Even if I have the main volume all the way down on the 192, I'm still getting sound from the sub. The sub is connected to direct out 3, and within the UC software, I have speaker management switched to A-B+C, with C being the sub. Even when I deselect C in speaker management, I'm still getting sound to the sub.
