wireless microphone

　　 Wireless Microphone , also called wireless microphone, can restore and amplify the sound. Compared with wired microphone, it is more convenient and more and more popular with consumers. It is widely used in KTV, audio-visual room and conference room. Perhaps so many people still think so: as long as the equipment, you can talk on it. In actual fact, if you do not understand its working principle and the use of precautions, it would not be able to really use the Wireless Microphone. Below, Wo sound engineering to share with you this knowledge. 　　How Wireless Microphone works: 　　Wireless Microphone is mainly composed of transmitting part and receiving part. The transmitter part is powered by a battery. The microphone converts the sound into an audio signal. After being processed by an internal circuit, a radio wave containing audio information is transmitted to the surrounding space. The receiving part is generally powered by the mains. The receiving antenna receives th...

　　When using a Wireless Microphone , there is always the problem of interference between the systems themselves. Although each system has frequencies or intervals of several megahertz, Intermodulation Distortion (IMD) can still cause interference between microphones. If there is not enough space between the intermodulation signal and the device's operating frequency, it is difficult for the receiver to pick up the signal from the transmitter. Typical phenomena are crosstalk between systems, frequent signal loss or excessive noise and distortion. 　　The minimum spacing between frequencies, depending on the design of the system receiver, may require an interval of 1 MHz from the nearest neighbor to the entry level receiver. The more expensive receivers usually have narrower adjustment "windows" that allow for a smaller intermodulation frequency separation between each system. 　　In order to avoid intermodulation distortion, choose the calculated frequency of mut...
