2.4G Wireless Stereo Audio Transmission

2.4G wireless stereo audio transmission is a high-fidelity dual-channel stereo transmission composed of one transmitter module and one or more receiver modules. The audio algorithm, utilizing A-LAW, enhances signal-to-noise ratio and audio signal fidelity. The communication protocol, employing A-FFC, improves stability and anti-interference capabilities.
