Yes. Totally get that. I was just surprised that the setting was so much lower for that channel than, say, the other guitar player's mic'd cab.
This is the info I was looking to verify. Thanks for making it perfectly clear.
On the TF board, the digital gain is the gain...if that makes sense. There's a lovely little image like a tuner that lets you know if your gain for that input is too low, too high, or just right (see photo). Once I got the gain settled down, the faders looked much like you'd expect instead of my channel being at -50 and everyone else being at or near 0.
Based on your and DunedinDragon's replies, I definitely need to go back and adjust patch volumes if I want to continue with having the XLR out disconnected, which I do. So that's what I'll do now. I have some time before the next gig so I should be able to get it done. If not - I'll stick with the big knob for now.
Thank you guys so much for taking the time to outline some of the finer points.
