 Oh, you're talking about measuring the mic stage (not the preamp stage). Yeah, you can't really do that.

It CAN be done, it just is not easy
After thinking about it for a while, I think I can do it with my DCX. I can go into the behringer with the RCA to XLR cable, then go out (no filters) balanced to the mic in. I can also come out of the behringer to an unbalanced line in to control for the response errors of the DCX. I know the behringer can handle unbalanced inputs and both balanced and unbalanced output so that just might do the trick.
I am sure you could also make a relatively simple circuit board to convert the unbalaced out to balanced but I am not sure if that would introduce any significant error.
All this to get a precise measurement at 6 or 7 hz where no EQ I know of can be used to tune the signal anyway
