ADAT machines

Like DTRS recorders, ADAT tape recorders use a video tape transport but running at a faster speed. Unfortunately most ADAT machines used a consumer tape transport that was not particularly rugged, often causing tape lacing problems which will damage tape. Only the later M20 and Studer ADAT machines used a much higher-quality transport that lasts well.

ADAT risks & vulnerabilities

While ADAT machines use standard S-VHS tapes, there are some issues which are specific to this multitrack digital format:

• The tapes run at around 4 times the standard VHS tape speed, so transports can wear out quickly.
• While expensive new, most ADAT machines used a transport common to domestic VHS machines, which do not respond well to heavy use.
• Direct digital transfer is preferable for making transfers, but this can be tricky without specialist hardware - especially when transferring multiple session tapes (16, 24, 32, 48 track sessions)

ADAT recording history

The first ADAT machine was released in 1991 and had a major impact on the recording industry and home recording. Like the DA models released by TASCAM, a major benefit was that they could be synchronised with other machines, allowing for people to build their recording capacity 8 tracks at a time.

ADAT’s use of ½ inch S-VHS video tape meant that the larger tape width was less susceptible to damage than the 8mm Hi8 tapes used by the DA-88 and DTRS. The S-VHS tapes could record 40 minutes and because 8 tracks of audio require a large amount of bandwidth, the tape moved up to three times the speed of the average VHS tape.

ADAT is still used in some industries and the recording industry, even if it has to a large extent been replaced by Digital Audio Workstations (DAWs).

ADAT subsequently referred to the Alesis ADAT HD24-XR, which featured hard disk recording rather than the traditional tape-based ADAT (now considered obsolete), but this machine too has now been discontinued.
