ULXP4 Wireless Receiver

ULXP4 Wireless Receiver Specifications:

• RF Carrier Frequency Range: 554.000 to 865.000 MHz
• Effective Range: 100 m (300 ft.) under optimal conditions (Actual working range depends on RF signal absorption, reflection, and interference)
• Audio Frequency Response: 25 to 15,000 Hz, (±2 dB (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
• Receiver Audio Output Level (±38 kHz deviation, 1 kHz tone)
