Shure UR2 Specifcations
Frequency Ranges
- RF Carrier Frequency Range: 518-865 MHz, depending on region
- Working Range:
- 150 m (500 ft.), under typical conditions
- 500 m (1600 ft) line-of-sight, outdoors for a single system
- Audio Frequency Response: 40 – 18,000 Hz, (+1 dB, –3 dB).
- Gain Adjustment Range: 10 to +20 dB
- Modulation: FM (45 kHz max. deviation), compander system with pre- and de-emphasis
- Dynamic Range: >105 dB, A-weighted
- Image Rejection: >110 dB typical
- Spurious Rejection: >90 dB typical
- Ultimate Quieting (ref. 45 kHz deviation): >100 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.
