Re: Large Diaphragm mics in low temperatures

["Toby Sinkinson" tobysinkinson]

I just got pretty close to those temperatures with a pair of nt1-a's withou=
t
any trouble...I think it was down to  -12 degrees celsius but probably
colder with wind chill...the homemade windscreen may have neutralized that =
a
bit though.

Some strange things happened to my hydrophone even thought the water was
warmer under the ice...a surge in preamp noise that appeared and hung aroun=
d
after about 15 minutes of recording.

I bundled my recorder up in sweater, hoping it might help with battery life=
.

2 cents,
