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 cup
