Introducing wireless microphones for you

The wireless microphone consists of several pocket-sized transmitters (which can be put in a pocket, the output power is about 0.01W) and a centralized receiver. Each pocket transmitter has a different operating frequency. The centralized receiver can simultaneously receive voice signals of different working frequencies from various pocket transmitters, and is suitable for stage podiums and other occasions.

When using multiple sets of wireless microphone systems of the same series, if possible, it is best to use an antenna splitter to minimize the mutual interference between the antennas on the original receiver. Or keep the wireless microphone receiver annunciator at an appropriate horizontal distance. Make each receiving signal device have better receiving conditions, avoid mutual interference between frequencies, and obtain better wireless signals.

The biggest technical bottleneck of using wireless microphones is the signal interference problem, especially the more frequencies used, the more serious the interference problem. Therefore, when using multiple wireless microphones at the same location, in addition to physical selection, interference should also be avoided. In addition to frequencies that do not interfere with each other and avoiding adjacent external signal interference, the receiver must also have excellent selectivity, and the emitted and received radiation harmonics must be filtered to a very clean level to avoid signal interference.
