At present, the wireless microphone used in the education market mainly uses analog U-band and V-band technology, digital infrared technology and 2.4G digital technology.
Its main scenario application is：
Method 1: In a classroom, fix a set of receivers (speaker amplification), one or two microphones;
Mode 2: Or only receive (loudspeaker amplification), each teacher with a separate wheat.

The first method is mainly to use the teaching microphone under the U-segment and V-segment of the analog technology. Compared with the traditional microphone, the volume of wheat is large, which is prone to the problems of serial frequency and mutual interference. It is difficult to modulate and maintain. In the high-density use environment of classroom, digital microphone is more flexible and easy to use.

Digital infrared wheat can basically meet the needs of teaching amplification, but installation must require high directivity, wiring more trouble.

2.4G digital wheat has always been in the domestic market, but at present there is only one XiiSound in China who has the ability to do well in anti-jamming and comprehensive stability. XiiSound scheme will make up for the new standard of wireless audio bidirectional in the domestic education market and achieve a new leap in the application of wireless teaching wheat.
