Specifications:

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
• 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.
• 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.

• Dynamic Range [1] @ 1 kHz, 1000 Ω load: 117.0 dB
• Equivalent Output Noise [1] typical, A-Weighted: 22 dB
• Power Requirements: +5 V DC (nominal), 10 V maximum (DC bias)
• Polarity: Positive pressure on diaphragm produces positive voltage on pin 3 with respect to pin 1
• Cable: 1.3 m (50 in.)
