Specifications

• System
  • Working Range: 91 m (300 ft) Line of Sight (actual range depends on RF signal absorption, reflection and interference)
  • Audio Frequency Response: 50 to 15,000 Hz (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) (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.
