Specifications
ULXP4 and ULXP4D Receivers:
RF Carrier Frequency Range
554.000 to 865.000 MHz
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 impedance1/4-inch output
