Operating Voltage
5 VDC
(pin 2 to pins 3 and 4)
11–52 VDC Phantom power
Polarity
Positive sound pressure on
diaphragm produces positive
voltage on pins 3 and 4 relative to
pin 1 (ground) on the mini TA4F
connector.
Positive sound pressure on the
diaphragm produces positive
voltage on pin 2 relative to pin 3 of
preamplifier output connector.
