Output Polarity
Positive pressure on the
diaphragm produces a positive
voltage at:

connector of the preamp
Pin 3 (black lead) relative to pin 1
(shield lead) at the output connector
of the microphone
Pin 2 relative to pin 3 at the output
connector of the preamp
Pin 3 (black lead) relative to pin 1
(shield lead) at the output connector
of the microphone
Power Requirements
