Manufacturer Specs
RF Carrier Frequency Range: 518-865 MHz, depending on region
Working Range with 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
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
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.
System Distortion (ref. ± 45 kHz deviation, 1 kHz modulation): <0.3% Total Harmonic Distortion typical
Power Requirements: 100 to 240 Vac, 50/60 Hz
Current Drain: 0.8 Amps max.
Operating Temperature Range: 0° to +135°F
NOTE: Battery characteristics may limit this range
NOTE: Electrical safety approval is based on a maximum ambient temperature of 35°C (95°F).
Housing: Galvanized steel
