yep, what dan said. you were definitely over-pushing the soft limiter. typically, limiters will allow you to crank the gain all you want and never go over certain point. The problem is your recording results in an overly compressed, "breathy", and quite unpleasant sound. If you didn't have it on you would have surely clipped well before getting anywhere near full gain on the mini-me.
i did the same thing when i ran the 722 limiter the first time and pushed it too hard testing its limits. soft limiters, IMHO, are meant to be used sparingly and in supreme dynamic situations where a huge transient might send you over. in mastering it's merely used to prevent overs and not really to compress. I'm not sure what you were recording, but if it was a rock concert, chances are it wasn't very dynamic. Thus pushing a soft limiter the way you did gave your undesired results.
