I use the tapeout from mp-2 >rca jack line in on my hd-p2. Keep the gain on zero for my mp-2 and do minute adjustment on the p2. Usually don't need much if any gain added. Maybe 10db. I'm also in the camp of use as little gain as possible on the mp-2. My mics run hot, but using the tapeout, I have never needed pads on my mics or in-line. This includes way fob or onstage (high db enviro's).
