Shure UC1

RF Carrier Frequency Range: 782–806 MHz
Working Range: 152.4 m (500 ft), minimum, under typical conditions; 487.6 m (1600 ft ) line of sight
Audio Frequency Response: 45 to 15,000 Hz, ±2 dB.
Gain Adjustment Range

• UC1: –6 to 34 dB
• UC2: –6 to 26 dB

Modulation: ±45kHz deviation compressor-expander system with pre-and de-emphasis
RF Power Output: UC1, UC2: 50 mW, typical
Dynamic Range: >100 dB, A-weighted
Receiver Audio Output Level (Maximum)

• +5 dBu typical, unbalanced output
• +14 dBu typical, balanced output

RF Sensitivity: UC4: –108 dBm at 12 dB SINAD
Image Rejection: 90 dB typical
Spurious Rejection: 70 dB typical
Ultimate Quieting (ref. 45 kHz deviation): >100 dB, A-weighted
Audio Polarity: Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 with respect to pin 3 of low impedance output and the tip of the high impedance 1/4-inch output.
System Distortion (ref. ±45 kHz deviation, 1 kHz modulation): 0.4% Total Harmonic Distortion typical
