• RF Carrier Frequency Range

470.000 to 865.000 MHz (Available frequencies depend on the applicable regulations in the country where the system is used). Refer to the frequency supplement supplied with the system.

• 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.

• 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
