System Audio Polarity
Positive pressure on microphone diaphragm produces positive voltage on pin 2 (with respect to pin 3
of XLR output) and the tip of the 6.35 mm (1/4-inch) output.
Operating Temperature Range
-18°C (0°F) to 50°C (122°F)
Note: Battery characteristics may limit this range.
Storage Temperature Range
-29°C (-20°F) to 74°C (165°F)
Note: Battery characteristics may limit this range.
