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
