I have a MiniMe and had exactly the same problem but only after I replaced my AKG300's (which apparently were not that sensitive) with AKG480's (which are more sensitive), I ran the 300's with the MiniMe as it came from the factory with no pboblems, then the first time I ran my new 480's with the MiniMe the levels were way too high and I was getting constant digital overs and the trimpots did not work, I modified the unit per the manual and now the combo works great, I guess we get the manual for a reason, school of hard knocks I suppose, Grider
