System
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

Note: Battery characteristics may limit this range.
Polarity
Positive pressure on microphone diaphragm (or positive voltage ap-
plied 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.
