To put it bluntly, the frequency used by everyone has other network signals, thus blocking the spread of the infrared wireless microphone's data signal. This type of interference enters the device according to the receiver's wireless antenna, so that we cannot accept the infrared wireless microphone normally. Data signal.

1. Infrared wireless microphone, especially when some high-power transmitters are in operation, cause a lot of spurious emissions. Perhaps the frequency it is working on is not the frequency that everyone uses, but because of out-of-band emissions such as internal parasitics and harmonic currents, it should very likely cause some additional emissions to fall into your application frequency, causing interference to the wireless microphone.

2. The working frequencies of other wireless network transmitting equipment, machinery, microphones, household appliances, and communication base stations may be the same as the frequencies used by everyone, which will interfere with the dissemination of infrared wireless microphone data signals.

3. Electromagnetic induction interference, some high-power experimental instruments will cause high-power harmonic current emission or magnetic field when they are working, especially when the distance is close. This kind of wireless network frequency radiation kinetic energy will be concentrated on some power circuits, causing part of the power circuit of the infrared wireless microphone receiver to fail to work.

Generally, when using infrared wireless microphone equipment, the first overall plan for the installation location of the equipment is carried out. The benefit of the overall planning is to bypass electromagnetic induction interference.
