Alesis Digital Audio Tape or ADAT, first introduced in 1991, was used for simultaneously recording eight tracks of digital audio at once, onto Super VHS magnetic tape – a tape format similar to that used by consumer VCRs. Greater numbers of audio tracks could be recorded by synchronizing several ADAT machines together. While this had been available in earlier machines, ADAT machines were the first to do so with sample-accurate timing – which in effect allowed a studio owner to purchase a 24-track tape machine eight tracks at a time. This capability and its comparatively low cost were largely responsible for the rise of project studios in the 1990s.
With locate points it was possible to store sample exact positions on tape, making it easy to find specific parts of recordings. Using Auto Play and Auto Record functions made it possible to drop in recording at exact points, rather than relying on human ability to drop in at the right place.
ADAT’s could be controlled externally with the Alesis LRC (Little Remote Control), which could be attached to the ADAT with a jack connector, and featured the transport controls and most commonly used functions. Alternatively the BRC (Big Remote Control) could be used, which included many more features which the stand alone ADAT did not have, such as song naming, more locate points and MIDI Time Code synchronization.
The ADATXT20 offers you eight tracks of true, linear 20-bit digital audio, without using external converters or multiplexers. You also get ultra-high fidelity 20-bit oversampling digital converters. For your advanced production work, the XT20 provides built-in digital editing features and 10-point autolocator/10-key numerical input system. It also offers a solid, six-pound die-cast aluminum chassis that’s designed for heavy-duty applications.
- Compatibility: With literally hundreds of thousands of ADATs still in operation today, it makes a great deal of sense to install at least one ADAT XT20 in your studio. Even if you don’t use it as your primary recording medium, many of the top recordings over the last decade were recorded to ADAT tape or are archived to this medium. You just never know when someone will walk into your studio with an ADAT tape for you to mix, edit or master. Implementing an ADAT XT20 into your studio couldn’t be easier! It’s rack-mountable and features analog (RCA and ELCO) and digital (Lightpipe) I/O. Remember, “An ounce of prevention is worth a pound of cure.”
- Backup and Storage: An ADAT XT20 will record a minimum of 40 minutes on each of its 8 tracks of better than CD-quality digital audio – that’s over 1.6GB of information! When you consider the relatively long shelf life of ADAT tape, how ultra-affordable it’s become and its durability and reliability (drop a hard drive on the floor, then drop an ADAT tape in its case…) an ADAT XT20 becomes an incredibly smart solution for backup and storage of your digital audio. Nearly every major digital mixer, recording medium and computer audio interface has implemented Alesis’ ADAT Lightpipe technology making transfer of your digital audio to an ADAT XT20 a breeze!
