Specs:

  • RF Carrier Frequency Range: 578-638 MHz
  • Working Range: UR1, UR2: 150 m (500 ft.), under typical conditions 500 m (1600 ft) line-of-sight, outdoors for a single system NOTE: Actual working range depends on RF signal absorption, reflection and interference
  • Audio Frequency Response: 40 – 18,000 Hz, (+1 dB, –3 dB). NOTE: Overall system frequency response depends on the microphone element
  • Modulation FM (45 kHz max. deviation), compander system with pre- and de-emphasis
  • Dynamic Range: >105 dB, A-weighted
  • Image Rejection: >110 dB typical
  • RF Sensitivity:  –107 dBm Typical 12 dB SINAD, –102 dBm Typical 30 dB SINAD
  • Spurious Rejection: >90 dB typical
  • Ultimate Quieting: (ref. 45 kHz deviation) >100 dB, A-weighted
  • Signal Polarity: Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on XLR output pin 2 with respect to XLR pin 3 and on the tip of the 1/4-inch output jack.
