TECHNICAL SPECIFICATIONSRF Carrier Frequency Range: 518-865 MHz, depending on region Working Range: 150 m under typical conditions, 500 m line-of-sight, outdoors for a single system Audio Frequency Response: 40 – 18,000 Hz,(+1 dB, –3 dB). Gain Adjustment Range: UR2: –10 to +20 dB Modulation: FM (45 kHz max. deviation), compander system with pre- and de-emphasis 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: 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) Overall Dimensions: UR2/BETA 58: 258 mm L x 51 mm Dia. Net Weight: UR2/BETA 58: 314 g (11.1oz.) without battery
