The Multi-channel Audio Digital Interface (MADI) is an interconnection standard between multi-channel digital audio equipment based on the dual-channel AES/EBU interface standard. It can serially transmit 56 channels of linearly quantized audio data over a 75Ω coaxial cable or fiber so that one sample per channel can be transmitted during an audio sampling period. It specifies 75Ω video coaxial cable and BNC interface connector. The output voltage peak of the transmitter should be 0.3~0.6V, and the longest coaxial cable length should not exceed 50m. If you use fiber optic cable, it can transmit farther distances.
