ADAT Optical Links

Rev 7

Added Frontier Design 11/2/97.
Added Soundscape Digital 8/17/97.

The Alesis ADAT Optical I/O interface is an 8-channel, 24-bit digital audio interface. Most of the new SGI workstations support the ADAT Optical interface, in addition to AES digital I/O, either built-in or via a low-cost option card. For more information on SGI audio specifications and available applications, please visit the SGI Audio Applications Directory.

Here is a short list of some Web sites containing information about products which support the ADAT Optical I/O format. Note that many of the ADAT Optical products seem not to have official Web pages. In these cases, I try to find Web pages from dealers who sell these products, or list a phone number at which you can request information. If you find more products, please let me know; I'll gladly add them.
