ULX WIRELESS SYSTEM
SPECIFICATIONS
NOTE: For a list of compatible frequencies that are usable in
your area, refer to the supplied frequency supplement.
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 absorp-
tion, reflection, and interference
Audio Frequency Response
25 to 15,000 Hz, ±2 dB
NOTE: Overall system frequency response depends on the mi-
crophone 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
