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
- Transmitter Gain Adjustment Range
ULX1: 25 dB
ULX2: 25 dB
- Receiver Audio Output Level (±38 kHz
deviation, 1 kHz tone)
XLR connector (into 600 ohm load): +3.9 dBV (line), –17 dBV (mic)
1/4 inch connector (into 3000 ohm load): –2 dBV
- Impedance
ULX1 (input): 1 Megohm
ULXS4, ULXP4 (output): 50 ohms at line level; 2000 ohms at mic level
- Modulation
±38 kHz deviation compressor-expander system with pre- and de-emphasis.
- RF Power Output
ULX1, ULX2: 30 mW maximum
- Dynamic Range
>100 dB, A-weighted
- RF Sensitivity
1.26 μV for 12 dB SINAD (typical)
- Image Rejection
80 dB typical
- Spurious Rejection
75 dB typical
- Ultimate Quieting (reference ±38 kHz
