ADAT Optical

A specific form of optical audio data transfer developed by Alesis for their ADAT machines. ADAT optical uses the same interconnects as the ubiquitous TOSLink two-channel format, but includes eight channels of digital audio data. ADAT optical was a key cog in the development of the original ADAT back in the early 1990s. Today it is one of the standard digital I/O connections found on many pieces of digital audio gear such as mixers and recorders.
