I just picked up a Model 12 and I'm planning to use it both with my hardware and as an interface for my computer. I'd like to just have it always on so it can be the normal audio interface I use with my computer even outside of working in a DAW. The display on the model 12 seems to be static on the levels and there's no screensaver as far as I can tell, should I be worried about the screen burning in over time if I just leave it on all the time? Wondering if anyone else just leaves it on permanently or for days at a time.
