I took a quick look at the specs and also looked at the equivalent
Sennheiser mono Cardioids.
The Sennheiser MKH is quieter and more sensitive by a fair amount. The
ME is about the same mic noise levels, but still maintains a fair lead
in sensitivity.
It's worth noting that this mic will handle up to 143 dB, considerably
louder than the Sennheisers. We don't ever have need of this sort of
thing out nature recording as we are never close enough to see high
sound levels. But it does point out something about the design
expectations for this mic. It's designed for recording fairly loud
sounds well, which is appropriate for it's intended studio usage.
The mechanical design worries me just a little the thin stalks the two
capsules are on constitute a weak point. Though if outside we will
probably have this in a wind enclosure.
As far as weather, I've seen nothing on that. It sure would be nice if
manufacturers would include environmental tolerances in their specs.
Good luck on your quest with the Uher.
Walt

Subject: RFI re Rode NT4 stereo mic.
Hello Naturerecordists,
Anyone out there 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, especially with reference to the specifications
copied below, which I lack the technical knowledge to understand.
Syd Curtis in Brisbane.
