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 direction in front of the microphone are corrected, the dotted line is substantially the pickup range, outside this range, the pickup will be insensitive. If the conditions, the proposed multi-point or find a 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 venue pickup and wireless microphones, pin 2: (+), Pin 3: (-) Sensitivity: 12dB usually the train travel time for the wireless microphone use of time, and the loading of the goods is the sound. While using the same frequency two wireless microphone, just as two trains while traveling on the same track, it will collide. It will become a "cuckoo Za Za, chirp chirp grumble grumble" noise, normal voice is unable to come out. Radio transmission is not linear, but the proliferation of multiple directions, reflection will encounter obstacles. For example, mixing tank water markets wireless microphones and conference rooms, the water will have a ripple, ripple interference between wireless microphones and digital infrared technology, causing a wave of high or low. Similarly, radio wireless microphone out the same as the distance increases weakened wireless microphones, hit a wall or obstacle, there will be waves or high or low. And sink like waves because of the location of this strength microphone and antenna, indoor vary.
