Shure ULXS4 - Specifications Overview; Transmitter Specifications; Receiver Specifications; Audio Output Specifications

10
RF Carrier Range
470,000–865,000 MHz
varies by region
Working Range
100 m (300 ft) typical
Note: Actual range depends on RF signal absorption, reflec-
tion and interference.
Audio Frequency Response
25 Hz – 15 kHz, ±2 dB
Note: Dependent on microphone type
Modulation
±38 kHz deviation compressor-expander system with pre- and
de-emphasis
Dynamic Range
>100 dB, A-weighted
Image Rejection
80 dB, typical
RF Sensitivity
1.26 µV for 12 dB SINAD, typical
Spurious Rejection
75 dB, typical
Ultimate Quieting
Ref. ±38 kHz deviation with 1 kHz tone
>105 dB, A-Weighted
Total Harmonic Distortion
Ref. ±38 kHz deviation with 1 kHz tone
0.3%, typical
Operating Temperature Range
-20°C (-4°F) to 49°C (120°F)
Note: Battery characteristics may limit this range.
Polarity
Positive pressure on microphone diaphragm (or positive volt-
age applied to tip of WA302 phone plug) produces positive
voltage on pin 2 (with respect to pin 3 of low-impedance out-
put) and the tip of the high impedance 1/4-inch output.
