I'm positive that I was only using the front buttons when I reproduced this problem...

Oh, of course. I just happened to be able to reproduce it when I did both IR and front panel buttons. It's possible that the usage of both controls at the same time had nothing to do with it. When I reproduced it, it was very intermittent. In ten minutes of trying, I only got it to happen twice.

I'm just trying to help figure out how to repeat the problem so that we can A) prove it's real, and B) help the Empeg folks track down the problem.

If, as Hugo said, the buttons trigger a piece of firmware that sends virtual IR commands to the mainboard, then there's a possibility that the new rotary control would do the same thing. If so, there's a possibility that the same bug might occur on the Mark 2's. If that's the case, then we should try our best to help find this bug before they start shipping Mark 2's in quantity. It would be a shame for more speakers to get blown because of it.
