Channel J1: 554 to 590 MHz
Channel M1: 662 to 698 MHz
RF Carrier Frequency Range: 554.000 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.
*Output Level: Microphone Level = Line Level - 20 dB
Transmitter Audio Polarity: Positive pressure on microphone diaphragm (or positive volt-age 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
Transmitter Gain Adjustment Range ULX2: 25 dB
Receiver Audio Output Level (+/-38 kHz deviation, 1 kHz tone):
XLR connector (into 600 ohm load): +3.9 dBV (line), -17dBV mic
