Linking digital equipment with digital I/O

Hi

I have a TC Electronics Fireworx that I use for recording and was thinking that I could connect it to my AES/BU with XLR cables... but I have two questions...
Do I need a word clock? If so, what sort of cable is it and how would i link it up and to what?
If I have a 96k project and the output of my Fireworx is 48k, how will that fit into the project?

1st, aes/ebu encapsulate it's own clock, like adat, but wordclock is always prefered if you can use it.

2nd, a 96khz project will ot work at all with the 48khz of the fireworx, BUT behringer has a thing called srcmatcher that convert samplerates on the fly between units. Probably exist at other manufacturers also, dunno...

sounds good, although i prefer not to buy behringer...
What sort of a cable and connection is a word clock and why is it superior to the AES/BU?

I don't know the exact type of cable needed, i know it coaxial 75ohms with bnc connector, and that it need a terminator.

The cable standard for external wordclocks is no better (in fact AES is probably much preferable as a cable spec). But a good dedicated wordclock has better stability than a cheap wordclock.

"RG59" with BNC connectors is the cable "type". You can get cheap old stock at Radio Shack in North America, or order from Redco.

Z Systems specializes in sample rate converters. RME also makes one or two units.

Hope this helps,
