Title: AES & S/PDIF
Post by: Wes on June 03, 2003, 04:34:34 PM
I've looked all over for the answer to this question.  There are some VERY informative posts about.  Some posts a little too informative.  Way over my head.  ???

I used to run v2>ad2k>multiset coming out of the xlr outs on the ad2k into the spdif in on the multiset via a custom audio magic presto 2 digital cable. I just ordered a v3 yesterday and I'm worried as to whether I'm still going to be able to do this on the v3 b/c on the ad2k I had an option to choose if I wanted AES or spdif out and I just set it to spdif.  The v3 doesn't offer this option i don't think.  Am I going to be able to come out of the AES on the V3 and into the spdif on the multiset via this same cable or do I need to need to get a spdif>spdif cable and do it the easy way?

thanks
Wes

Did you check the V3 manual on the Grace website Support page?   :P

The V3 is set up to transmit digital signals from three different outputs:

Coax (75 ohm)
XLR1 (110 ohm)  - labelled as AES1 in the V3 manual
XLR2 (110 ohm)  - labelled as AES2 in the V3 manual

Coax and XLR1 share the same transmitter capable of either AES/EBU or S/PDIF, selected by internal jumper

XLR2 has its own transmitter which always transmits AES/EBU.

I think what you want to do is use XLR1 to send a S/PDIF signal.  No problem.  Set the internal jumper to S/PDIF (see the manual for the jumper, I think it's labelled "consumer").  If you're to use XLR1 to send S/PDIF over an XLR > coax cable, you technically should use a 110 > 75 ohm impedance transformer.

That said, I don't use one and it seems to work just fine for me.  I run S/PDIF XLR1 > coax for my DAT, and use the coax S/PDIF output for patchers (of which I rarely have any, it seems).

the v3 does have a aes out so you should be able to use your custom cable

i run the AES2 into the dap1 and leave tails out of AES1 and spdif for whoever needs it.

yes bean, you do

+T to Brian for allowing patchers...

here's a thread from the other day on the oade board including comments by Doug on use of the professional setting on the AES outputs
