AES/EBU & Sync input question

[garf]

Bit of a newbie question here. I just purchased a used Apogee AD-500 A/D converter to upgrade my signal path (was using the internal A/D in the Tascam CD recorder before). So from my mic pre's I am going directly to the Apogee, and from there directly to a Tascam CD recorder. The AES/EBU digital audio output is a no-brainer, but what about the sync input? Is this anything I would use when I am working only with 2 channels (just recording a solo harp) or is this only when you have multiple A/D that need to be synced together?

That would be for chaining a bunch of stuff together. With your setup, the tascam is getting sync from the aes/ebu.

Aside from syncing multiple digital devices you could also use an outboard high quality clock to improve jitter of the converters but since the Apogee already has a kick ass clock, it would be hard to find a better one.

Thanks Jason, you saved me alot of head scratching (which can be messy)
