ADAT XT-20

The ADAT XT-20 is an MDM format that allows multitrack digital recording on conventional S-VHS tape.

The ADAT XT-20 was a format from the Alesis company to replace the ADAT. The main evolution was that it increased the resolution to 20 bits. As sales of this were scarce, Alesis released the ADAT LX20, a cheaper version of the ADAT XT-20.
