ULXP4 and ULXP4D Receivers:

RF Carrier Frequency Range*
470.000 – 865.000 MHz
*Note:  Frequencies above 698.000 MHz are for use outside of the U.S.  Contact your local dealer, distributor or Shure for more information.

Effective Range

100 m (300 ft.) under optimal conditions

NOTE: Actual working range depends on RF signal absorption, reflection, and interference

Audio Frequency Response

25 to 15,000 Hz, ±2 dB

NOTE: Overall system frequency response depends on the microphone element.

*Output Level: Microphone Level = Line Level – 20 dB

Transmitter 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
