RF Carrier Frequency Range
518-865 MHz, depending on region
Working Range
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
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
Image Rejection
>110 dB typical
RF Sensitivity
| UR4S |
–110 dBm Typical 12 dB SINAD |
| –105 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
UR2: Two 1.5V AA batteries
UR4:100 to 240 Vac, 50/60 Hz
Current Drain
UR2: 180 mA max. (normal RF power setting)
240 mA max. (high RF power setting)
UR4S: 0.8 Amps max.
Battery Life (Typical)
UR2: 9.5 hours (low power)
6 hours (high power)
Operating Temperature Range
–18° to +57° C (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).
