My guess is,I am way less qualified to answer than most who frequent this forum, but it appears you have no takers , so,since I think I can help, here goes. You might guess what a bridge is (thats all I can do, (tho it has to be obvious)so if you understand what an adat is,I am calling that total.( I just do have a concept) So I am assuming(yes I know the thing about that) the term adat is equally foreign, as it was to me. If you've ever used a stereo [*hi-fi] vcr to record audio, you might feel as do I and understand the quality there, without any video entering into the"picture". Try it if you never have, its one the great "ironies" of life to me anyway, the fact you can buy a stereo [*hi-fi] video cassette recorder, and forget about 80% of the width of the tape, (the video area),only to utilize the puny remaining portion for the audio part of your program.And knowing what a fantastic job of recording audio is accomplished from seeing,or "hearing" it(cd-qualityIMHO), makes a person think, "wow wouldn't it be great to use the whole tape width for audio!"...Well,Thats what an adat is, IF I have got it right that is... I do hope to have been helpful to you, but in any event, BEST of luck to you!

THANKS FOR COMMENTS

It's a meter bridge that mounts across the back of the BRC.

Actually, hi fi vhs does use the interleaved portion of the tape along with the video. They also employ a dbx type nr in the process. However the dbx works better in this scenario as there is no head bump effect to cause the dbx to track inaccuratly.

The edge tracks on a hi fi vhs are not hi fi at all..

I was thinking it was one of those interfaces in the older Pro Tools systems that let you record back and forth from an ADAT, as well as provide sync. I'm basing that on the fact that they include "16 bit" in the name - why would a meter bridge have a bit depth?

But I'm probably wrong.

No I think you may be right! :tu:

thanks all.

I posted this question on various forums and the overwhelming consensus is it's specific to Pro tools systems and lets you..erm...do something with ADAT compatible machines. That "doing something" I think is recording to such a machine but I don't know.

To the best of my limited knowledge it is a digital link between ADATs and Pro Tools to allow digital transfers from ADATS to PT while recording other PT tracks. There are products like the Octapre using the ADAT bridge protocol that let you add eight channels to a Digi 001 or 002, in effect letting you upgrade from 2 or 8 tracks of simultaneous inputs to 10 or 16 tracks respectively.

On the HD192 interface, the ADAT bridge features are built into the box. And they can handle the higher bit (20 bit) ADATs.

Here are two links regarding the specs.
