ADAT Cable length

Hello!

I little question.

How long can be the ADATA (TOS link) cable for the use of the UR824?

I’m looking to this 20m cable but I don’t know if is too long

http://en.wikipedia.org/wiki/TOSLINK see under design You maybe able to get away with that but I would worry about jitter.

mmm, so will be better if I buy the 10mts one just in case! and 5mts so I can check how many jitter I get using each one. and buy longer XLR cables! :stuck_out_tongue:
