Thanks, Rob -- One subtlety I didn't mention is that the PMD-670
hadn't been used in a few weeks, and the time of day was lost. I
don't remember that happening before, and I have to check if
there's a battery for that... But perhaps there IS a realtime
clock battery, and it was low or flakey, and this threw
something off.
I guess I'll find out if it's repeatable over the next few days.
I've got a couple of location sessions coming up. Fortunately,
both are favors, not for $$$.
I'm wondering if perhaps the mics got REALLY damp, so damp it
took weeks (at an ambient 75% humidity) to dry out. That is a
real, though somewhat remote, possibility. Although I don't know
if a damp (and presumably limp and wrinkly) diaphragm would
produce sibilance.

Subject: Re: [Nature Recordists] sibillance with NT1-A pair
So the problem is not repeatable now? Moisture would seem to be
the
#1 suspect, but I hear recordings from 20 NT-1A's we have in
regular
circulation and I don't recall hearing distortion like you
describe
from them (or the 6 I use). With this track record in mind, if
they
produce the problem at the same time, as Klas inquired, I'd
guess
that points to the pre or a intermittent relation the NT-1A's
have
with the 670 pre. Rob D.
