I agree with everything written here. 24 bit, -12 level, no low cut, etc. Shows I have recorded either via the line in, external mics or the internal mics have been impressive. I really don't mind the mini-jack input although I am aware its analog. Batteries (Duracells regulars or Ultras) went over 5 hours with no problem. I can't tell you how long they last because I throw them in a re-cycle bin at work after I am done with them. All I can say is after 5 hours, I still have 2 bars left. But I don't think that means they are half good. I rarely attend a show that exceeds 5 hours anyway. In general, I am happy with this deck. And not having to buy DAT tapes anymore is a BIG plus.
I did have trouble finding that HOLD button in the back once. I'm going to put gaffer's tape on it now because it is really hard to find it in the dark. Good idea!
