Anyone out there doing nature sound recording who has used the Rode NT4
Stereo Condenser mic., and can comment on it - especially as to how it
stands humidity, which is sometimes a problem with otherwise excellent
microphones?
MusicLab in Brisbane are the most helpful commercial firm (of any sort of
business) that I've dealt with. In a couple of days they fixed my 36 yr-old
Uher recorder to satisfy my whim to record an Albert's Lyrebird in the same
place and with the same recorder and Uher mic where I made my first lyrebird
recording on 22.06.68. (Wish me luck for tomorrow morning!)
And when I was collecting the Uher, MusicLab volunteered the advice that
the NT4 is an excellent mic, and modestly priced for such high quality.
With such a recommendation from MusicLab, I sit up and take notice.
Be glad of any advice
Syd Curtis in Brisbane.
