| Specification |
- ULXP4 and ULXP4D
Receivers:
- RF Carrier Frequency Range*
470.000 – 865.000 MHz
*Note: Frequencies above 698.000 MHz are for use outside of the
U.S. Contact your local dealer, distributor or Shure for more
information.
- 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 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
