• RF Carrier Frequency Range 470-952 MHz, depending on region
• 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 microphone element
• Gain Adjustment Range
- UR1: –20 to 35 dB
- UR2: –10 to 20 dB
• Modulation FM (45 kHz max. deviation),
compander system with pre- and de-emphasis
• RF Power Output See table above.
• Dynamic Range >105 dB, A-weighted

• 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.
