Signal Polarity
Positive pressure on microphone diaphragm (or positive voltage applied to tip of
WA302 phone plug) produces positive voltage on XLR output pin 2 with respect to XLR pin 3 and on the tip of the 1/4-inch output jack.
System Distortion (ref. ± 45 kHz deviation, 1 kHz modulation)
<0.3% Total Harmonic Distortion typical
