Input is locked with the Clean Sense at -12, never even turns yellow.
The cab that the rig loads with doesn't clip, but it's significantly louder than a typical profile - if I've got the speakers turned up to a comfortable volume for a different patch, and load this one, it's insane. Combined with one of my favorite cab profiles, it clips the KPA's output. However, I don't want to save that cab with the volume turned all the way down because then it's too quiet for every other amp, and having to save two copies of the same cab is annoying.
The cab settings are stored as a part of the Profile-any other rig using the same cab does have its own settings unless you lock the cab of course.
