2.4G wireless stereo audio transmission




2.4G wireless stereo audio transmission is a stereo dual-channel high-fidelity transmission composed of a transmitting module and one or more receiving modules. The audio algorithm uses A-LAW to improve the signal-to-noise ratio and the reproduction of audio signals; the communication protocol uses A-FFC to improve the stability and anti-interference.
