Thank you Klas and Rob,
I knew about Rob's NT2000s out in the elements for months, including
all winter. My specific application is recording at a three-day
390-mile sled dog race every January. This past year, I banged my head
on some serious battery drain issues with my Hi-MD recorders at -20F
and lost some data, but my Shure 183s and AT3032s seemed to hold up
fine. I got the recorder power problem figured out, but I'm wondering
if it's wise to count on condensers (AT3032s) in that kind of extreme
cold, or to maybe pack along a pair of dynamic mics for deep backup.
