Recently, the technology of "a multi-channel audio synchronous transmission circuit" independently developed by S-TRACK has obtained the invention patent certificate issued by the State Intellectual Property Office (Certificate No.: ZL 2016 1 1175421.3).

The invention proposes a solution for multi-channel audio transmission. The multi-channel analog audio signal is processed by I2S encoder, analog-to-digital conversion is completed, digital audio is output in parallel, digital audio is processed by TDM encoder, serial output is 1 channel TDM digital audio, 1 channel TDM digital audio is processed by 4B / 5B encoder, NRZ-I encoder and MLT-3 encoder in turn, and finally the circuit is completed Transmission. The invention introduces 45 / 5B encoder, NRZ-I encoder and MLT-3 encoder into TDM audio transmission system by using synchronous Ethernet technology for reference, which effectively solves the problem of synchronous transmission of data and clock.

With the core values of "truth-seeking, diligence, innovation, focus, efficiency and win-win", S-TRACK has always focused on the R & D and production of audio products, and is constantly committed to providing users with professional audio products and overall solutions in the fields of conference, education, etc. It has won more than 50 patents, "national high-tech enterprise", "top 10 brands of digital conference", "top 10 innovative enterprise brands" and other honors.
