UHF-R Wireless Handheld Transmitter with Beta 87C Cardioid Microphone.
UHF-R Wireless Handheld Transmitter with Beta 87C Cardioid Microphone.
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.
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:
