Dimitrios,
I'm not sure AES/EBU carries clock. I thought it didn't.
I may be wrong. Better check on that one.

Hi,
I have ordered the mytek digital clock which has 8 wc outs and one AES =
out.
I suppose the AES carries the wordcloc sync, right ?
Then with a AES to bnc transformer adaptor which tramnsforms the =
110ohms
to 75 ohms I can probably connect another device with bnc wordclock =
input
, right ?
Now here is one nice question.
A AES/EBU distributor from Aardvark (1 to 6)which accepts one aes =
input and
outputs to 6 would that work as clock distributor ?
To further use 110/75 transformer adptors to connect more devices ?
Regards,
Dimitrios

It will work just fine. I have done this sending AES out of my Mytek =
Stereo96 A/D converter to a Lucid GenX-6 with the Lucid set to =
distribute the clock signal. Just make sure the Aardsync can slave to =
sample rates above 48K if you intend to use them.

Hey Gang,
I think that if someone were to try to jam "AES Sync" into a word clock
input, they would fail miserably.
AES Sync (or AES Black, as it is sometimes called) is a complete AES 64
bit digital word, with preamble bits, status bits, et al, but with
zeroes occupying the audio bit locations (hence the 'black' or 'silence'
designation), output at the selected sample rate. It is a very good
digital clock source, if your equipment has the appropriate port. The
folks who originally created the format worked hard to make their system
capable of self-clocking. Works well on long cabling, too, with proper
cable types and proper termination.
Word clock, on the other hand, is simply a TTL-level pulse (5V p-p) at
the selected sample rate. It is useful, as well, but don't get the two
confused. Still needs proper termination, but not very good with long
cables. "Super Clock" is a wordclock pulse at 256 times the selected
sample rate. Not used too much any more, but still available, if
needed. My Rosendahl has one output which can be set to this rate.
Check any of these signals with a scope - you'll see what I mean.
Canare 110<>75 transformers are wonderful things, but they don't change
AES Sync into word clock, or vice-versa.
Also, clock distribution systems should not introduce sufficient delays
as to be problematic, especially in a project studio or small commercial
studio. Get to the radio/TV station sized facility, and then we can
talk....
Happy clocking,
