제품스펙

• ULX2 Transmitter Input

• 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

• Transmitter Gain Adjustment Rang

   - 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 microVolt for 12 dB SINAD (typical)

• Image Rejection  80 dB typical

• Spurious Rejection  75 dB typical

• Ultimate Quieting (reference +/- 38 kHz deviation)  >105 dB, A-weighted

• System Distortion (reference +/- 38 kHz deviation, 1 kHz modulation)  0.3% total harmonic distortion, typical

• Power Requirements

    - ULX1, ULX2: 9V alkaline battery; 8.4 V Nicad optional
