I wish I had suggestions about what is happening or how to address
it, but I've found that some mics perform very differently with MD
PIP mic pres and even between different MD models/brands. You might
recall the 14dB drop in gain that's been confirmed in 3 tests for the
NT-4 with the NH900 HiMD-- totally unexplainable. Until we figure out
what's going on, I've resorted to judging performance in terms of
specific combinations of mics and pres. Some combinations work better
than one might expect, others much worse than the specs predict.
Maybe something related to the PIP phantom powering even for mics
that don't require it?  Rob D.
