System Specifications

• 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)
• Polarity:  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.
