Thông số kỹ thuật

Type: Condenser (electret bias)

 Polar Pattern: Cardioid

 Frequency Response: 50—17000 Hz

 Current drain: 62 ±10 mA, typical (Vss = 6.0 to 9.6 VDC)

 Battery life: 7 hours (based on alkaline battery)

 Dynamic Range: > 100 dB minimum, A-weighted

 Gain Adjustment Range: -6 to 34 dBs

 Modulation: ±45 kHz deviation

 Polarity: Positive pressure on the diaphragm produces a positive voltage on pin 2 of the          XLR output of the UC4 receiver.

 Transducer type: Electret condenser

 Power Requirements: 9V alkaline battery

 Temperature Range: Operating: (20 degrees to 120 degrees F); Storage: (20 degrees to 165 degrees F)

 RF Carrier Frequency Range: 692-716 MHz (UB), 782-806 MHz (UA)

 Working Ranges: 250 ft. (75 m) typical, 800 ft. (250 m) line-of-sight

 Note: actual working range depends on RF signal absorption, reflection, and interference

 Minimum Distance Between Transmitters: 1 ft. (.3 m)

 RF Power Output: 50 mW Max (conducted), 30 mW Typical (radiated)
