UHF-R handheld transmitters
boast a rugged, lightweight construction and an antenna design
which advances RF transmission reliability.
The transmitter design allows for interchangeable microphone
cartridges. The UR2 is offered with SM58®, SM86, SM87A, Beta
58A®, Beta 87A™, Beta 87C™, and KSM9. UHF-R
Wireless Systems feature KSM9 as the premier choice in handheld
vocal microphones. |

| Specification |
- RF Carrier Frequency Range
470-952 MHz, depending on region
- Working Range
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
–10 to +20 dB
- Modulation
FM (45 kHz max. deviation), compander system with pre- and
de-emphasis
- RF Power Output
10 / 50 mW
- Dynamic Range
>105 dB, A-weighted
- Signal Polarity
Positive pressure on microphone diaphragm 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
Two 1.5V AA batteries
- Current Drain
180 mA max. (normal RF power setting)
240 mA max. (high RF power setting)
- Battery Life (Typical)
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).
