Are you recording to JB3 or laptop? If laptop, then use the program's meters. If JB3, then you need to find a way to convert to optical. I use a 312 with no problems. One great thing about the MiniMe is that you can guesstamate where the levels should be and then use the soft limit to prevent clipping. Granted, it limits the dynamic range somewhat, but it's a nice feature to have if you can't always be checking or adjusting levels. Personally I love everything about the MiniMe except that it is long instead of wide.
