Re: Nether regions
It's not that the manual states auto switching. What I'm trying to say is,
When you choose jack type A the output is automatically going to be....
When you choose jack type B then the output is automatically going to be....
They don't imply any automatic electronics or anything, just a fixed output that will be designated by jack type chosen. If that makes more sense?

Plugs and Jacks
Just to hit this again:
Generally (and oversimplifying a bit), when you take a balanced output on a TRS jack, and plug a TS plug into it, you'll ground one leg of the balanced output (the R). So, instead of having:
(i) a signal voltage that varies between 0 and 2x (where x is the maximum voltage on a particular leg) -- it's 2x, because when one leg is at +x, the other is at -x;
you will instead have:
(ii) a signal voltage that varies between 0 and x -- it's just x, because all you have is one leg that goes to x, and ground.
The bottom line is that you've cut the signal by about 6 dB.
This isn't the same thing as changing from +4 to -10 nominal level. The difference between +4 and -10 is 11 dB and change (it's not 14, because +4 and and -10 are referenced to different levels: .775 and 1; you know, the dBu vs. dbV thing).
But -- as is the case in some, but not all, situations -- you can work around the whole nominal level issue by adjusting the gain in any event.

sjjohnston, I'm still trying to figure out which side of the mic to sing into.
You're way over my head
If it sounds like I don't know what I'm talking about, it's because I don't know what I'm talking about.
I honestly appreciate the info though, seriously, I just wish I could put it to use somehow
