I bought this ADAT not working...currently being worked on by my repair tech for my studio. I used many of these machines throughout the 90's and they were pretty good for the most part. Some people are still using them, but most have gone to hard disc recording over tape-based recording. I bought a few of these for my studio as I transfer older formats like this to digital files for various customers (Outsidedown Productions) for remixing or archiving as the master tapes often deteriorate. This machine was in great condition and hopefully just needs a minor repair to get up and running well.
