Features |
Beta87C Vocal
Microphone
The Beta 87C offers an extremely smooth, tailored response for a
warm, natural sound. The cardioid polar pattern compensates for the
isolation often associated with the use of personal
monitors.
- Cardioid,
Condenser
- Frequency response: 50 to 20,000
Hz
- Highly consistent cardioid
pattern offers excellent rear rejection
UR2 Handheld Transmitter
- RF Carrier Frequency Range: 470
– 952 MHz
- Switchable RF Power (10/50 mW),
country dependent
- Battery Life: Up to 9.5 hours
continuous use

- RF Carrier Frequency Range
470-952 MHz, depending on region
- Working Range
150 m (500 ft.), under typical conditions
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
- 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
- Current Drain
UR2: 180 mA max. (normal RF power setting)
240 mA max. (high RF power setting)
- 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).
- Overall Dimensions
UR2/BETA 87C: 254 mm L x 51 mm Dia. (10 x 2 in.)
- Net Weight
UR2/BETA 87C: 325 g (11.5 oz.) without battery
- Housing:
UR2: Aluminum die-cast handle and aluminum machined battery
