I'm wondering if there are some factors affecting condenser mic
performance that we are not yet accounting for. My Rode NT2000
"studio mics"  http://www.rodemic.com/microphone.php?product=3DNT2000
have been outside, 24-7, since September of 2007 without breaking up,
whining-- experiencing no difficulties. From 100% humidity to -24F.
More details: http://tinyurl.com/4wx55m  NT1-A's and MKH's are
resistant, but based on hundreds of field hours on all of these mics,
the 2000's seem to be on another level. Rob D.
