Could someone tell me something more about this particular miniature microphone. I got it from a friend who told me that is was some special microphone for Nagra SNST-R tape recorder (as he was told when he got it from his friend). It used to have a square metal screw-in three pole connector on the other end - but friend of mine cut it and tried to solder it to a standard microphone jack to fit his Sony pocket voice recorder. However, he wasn't satisfied with the sensitivity of this external mic so, continued using built-in and gave this one to me.
As you can see from photos it is quite small, covered with ugly looking black rubber (just to protect it?) Microphone capsule under this rubber coating appears to be 3D rectangle shaped with two narrow cut-outs on the front side.
Can someone tell me something more about this microphone: what kind of type is, sensitivity, how it can be connected to a non-Nagra equipment (my guess it that some power to it has to be supplied?).
Any further info is more than appreciated!
