jeez i feel dumb. I have been reversing the self noise and sensitivity fig=
ures in my head. I just checked online, and of course you are right. I wa=
s feeling surprised they measured almost as quiet as modern low noise mikes=
-- but they don't.
on the other hand, i never use the screw-on pads so that's one less source =
of error. I even checked to make sure the phantom voltage was set correctl=
y on the MP-2 ;-)
I'll just have to see how nervous the frogs are. They shut up when i get w=
ithin about 10 feet to their general location (I have never been able to lo=
cate them visually), but I'll just have to leave the stuff set up and see h=
ow long it takes them to start up again when i walk away. There are 2-3 of=
them calling, and they are spread out over about 20 feet, which will put s=
ome of them off mike if I get too close to the 'major'. I'll just have to =
experiment.

your signal to noise ratio. Once sound has entered the recorder the signal=
