主要功能
可以从超?1400 个预先编入的频率中进行选择,同时通过“自动选择频率”功能可以立刻获得清晰的频道?/span>

技术规?/span>
RF Carrier Frequency Range 470000 to 865000 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 Range ULX1: 25 dB
ULX2: 25 dB
Receiver Audio Output Level (±38 kHz deviation, 1 kHz tone) XLR connector (into 600 ohm load): +39 dBV (line), ?7 dBV (mic)
1/4 inch connector (into 3000 ohm load): ? 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 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
ULXS4, ULXP4: 14 - 18 Vdc (negative ground), 550 mA
Battery Life 8 to 9 hours (with 9V alkaline battery)
Operating Temperature Range - 20° to 49° C (- 4° to 120° F)
NOTE: Battery characteristics may limit this range
Overall Dimensions ULX1: 965 mm H x 67 mm W x 267 mm D (386 x 268 x 110 in)
