Further Technical Specs

Working Range:
91 m (300 ft) Line of Sight
Note: Actual range depends on RF signal absorption, reflection and interference.

Audio Frequency Response:
50 to 15,000 Hz
Note: Dependent on microphone type

Total Harmonic Distortion (Ref. ±33 kHz deviation with 1 kHz tone):
0.5%, typical

Dynamic Range:
100 dB, A-weighted, typical

Operating Temperature:
-18°C (0°F) to 57°C (135°F)
Note: Battery characteristics may limit this range.

Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 (with respect to pin 3 of low impedance output) and the tip of the high impedance 1/4-inch output.

NOTE: All Specifications are subject to change. Performance may vary depending on country regulations and operating environment.
