Hi, I'm searching for a BNC SPDIF-to-optical cable. I don't know if such a cable exists. I do know people use BNC-to-coax digital cables on the SD7xx recorders, but I need an optical end to run the digital signal to my Alesis multitrack recorder. If anyone would be willing to make me such a cable, I'd be happy to pay you.
Thanks,
Tom
PS - Apologies for posting in Taper Chat, not sure where this post should go.

no such thing exists that i am aware of. you could use a hosa converter.

They sell the adapters at pretty much any electronics store, including radio shack.

Ya I just use the adpaters..

Thanks for your replies! I'll check out those links and test out what I buy tomorrow and post back here if they work or not in passing the SD722 digital out into an optical signal. I could also use it to take an optical out from another device, if I ever need to. I know I did that back in the DAT days.

these are just BNC>RCA adapters. RCA meaning COAXIAL (S/PDIF)
you need a converter box, to convert the Coax cable (S/PDIF) to an optical signal.
here's a box by m-audio, they are known and well respected
http://www.m-audio.com/products/en_us/CO2-main.html
cheaper here: http://www.amazon.com/Midiman-M-Audio-Coaxial-Bi-Directional-Converter/dp/B00006J074
here's another that's much cheaper, not sure of how it performs though.

For digital format conversion (coax to optical), I strongly recommend the Hosa ODL-276 or -276A. The A designation I believe supports up 24/96, while the regular version supports some lesser bit-depth and/or sample rate threshold (not sure what it is). Bulletproof, easy to power. The A model runs around $55 (http://www.fullcompass.com/product/236228.html), similar price to the M-Audio units. Back when JB3s hit the market a bunch of years ago, there was some anecdotal experience suggesting the M-Audio boxes occasionally caused problems. I forget the details at the moment. (http://www.scuba2000.com/forum/images/smilies/scratchhead.gif) YMMV.

i may be wrong here, but i think that if you run your 722 optically into your HD24, you will loose the ability to add more than the 2 channels from the 722 in the Alesis. In other words, if you have an optical signal going in and it only contains 2 channels, it will render your other 22 channels useless.
i'll give it a try next week and report back with my findings.
oh, and to answer your question, there is a $50 Hosa box that will do what you are looking to do.
722->coax output->coax/rca adapter->spdif cable->hosa box->toslink cable

also check out the fostex cop-1. It does 24/96.It will recogonize scms, however your alesis,
should not. I have used the fostex since 2000. Running scms into my alesis masterlink.
No problems ever and the alesis does not pass scms through so all copies are a ok.
best of luck

The RME Adi-2 will do the job (and more), but it does come at a price. I have seen the M-Audio CO2, it does the job as well.
