Topic: Sony PCM D100 Microphone Jack

[ghibliss]

Can anyone confirm how the microphone jack on the Sony PCM D100 is wired?  Is the jack a 3 wire stereo jack (tip, ring, sleeve) or is is it a 4 wire TRRS (tip, ring, ring, sleeve).  I am building a microphone battery box and would like to know how to wire the microphone output of the battery box to the microphone input of the recorder. I know that the recorder has a 3.5mm jack on it.
