Specifications
Frequency Range and Transmitter Output Power
RF Carrier Frequency Range
518-865 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 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
RF Power Output
See table above.
Dynamic Range
>105 dB, A-weighted
Image Rejection
>110 dB typical
RF Sensitivity
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
UR1, UR2: Two 1.5V AA batteries
UR4:100 to 240 Vac, 50/60 Hz
Current Drain

240 mA max. (high RF power setting)
UR4D, UR4S: 0.8 Amps max.
Battery Life (Typical)
UR1, UR2: 9.5 hours (low power)
6 hours (high power)
Operating Temperature Range
–18° to +57° C (0° to +135qF)
NOTE: Battery characteristics may limit this range
NOTE: Electrical safety approval is based on a maximum
ambient temperature of 35°C (95°F).
