Working principle editing

The working principle of the wireless microphone system: the transmitter is powered by the battery, and the microphone converts the sound into an audio electrical signal, and after being processed by the internal circuit, the radio wave containing the audio information is transmitted to the surrounding space.

The receiver is generally powered by the mains, and the receiving antenna receives the radio waves emitted by the transmitter, processes the internal circuit, extracts the audio signal, and sends it to the sound reinforcement system through the output signal line to complete the wireless transmission of the audio signal. A receiver can usually contain 1 set, 2 sets or 4 sets of receiving circuits, respectively receiving signals of 1, 2 or 4 or 8 to wireless microphones, which are called "one for one" and "one for each". Two" or "one for four" one for eight models. Among them, the one-to-two model is the most common.
