FM broadcast is a device that transmits broadcasts by wireless transmission. It has the characteristics of no vertical poles for wiring, wide coverage, unlimited capacity expansion, and convenient installation and maintenance. It solves the problems of traditional cable broadcasting wiring difficulties, complicated installation, and poor scalability. For the current large-scale and wide-area schools, FM broadcasting has the superiority that traditional cable broadcasting cannot match.

Application principle


The audio signal collected by the system is modulated to a high-frequency signal of a certain frequency and radiated into the air. The receiving end receives the high-frequency electric wave containing the audio signal. Through frequency selection and amplification, the audio signal is detected by the detection circuit, and then passed Positive, the power is amplified and restored to the original audio signal. This process is the wireless broadcasting system.
