Product Name: diversity single-channel wireless receiver IX-R11 Series: Wireless Microphones microphone pointing schematic As these points to how it was, you can try to find a microphone. As shown, the arrow in front of the microphone are corrected, the dotted line is the approximate range can pickup in microphone outside this range, where domestic sales, pickup will be insensitive. If the conditional microphone, recommendations or find a more pointed the microphone to try, we can understand the significance of the point. Technical parameters: the number of single-channel group channel panel LCD display LCD can display RF / AF signal strength, SQ setting, transmitter battery capacity and operating frequency oscillation mode PLL frequency synthesizer phase-locked Frequency Stability ± 0.005% (10 ~ 50 ℃) Carrier frequency UHF: 721.100MHz ~ 860.100MHz RF Transmitter Output: 30mW maximum audio input level: -10dB audio output level XLR connectors: -13dBV, 1/4-inch fittings: -2 dBV output impedance XLR connectors : 200 Ω 1/4 inch connector: 1kΩ XLR balanced output impedance Pin 1: Ground wireless gooseneck microphone rental, Pin 2: (+), Pin 3: (-) Sensitivity: 12dB usually Product Name: Digital Conference System Host Products: Hand in Hand Digital Conference System Specifications: Power Host: 200W unit: 1.5W output level 1Vpp SNR ≥80dBMIC sensitivity 5mV Frequency Response 80Hz ~ 15KHz ± 3dB bass and treble adjustment Bass: ± 10dB / 100Hz Alto : ± 10dB / 1KHz Treble: ± 10dB / 10Hz Product Description: HS-9800 digital conference system, bringing together a number of advanced design elements.
