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.
