SP-DIF and unstable SFP as wordslave.

Hi,

Did a search on this topic in this forum and saw this has been discussed before. Does anyone know if there´s a reliable solution to the unstabiblity in slaving SFP to an external wordmaster through SP-DIF?

I´ve tried replacing SP-DIF modules - no luck. Pulsar2 and SFP 3.1c.

if you use S/PDIF cinch then you need a 110 Ohm cable, which is a rare item.
The 'regular' connectors may work on short distance, but it's a trial and error process and you have to listen very carefully to sort out the good ones.
I use S/PDIF for monitoring my mixer's master out, but for recording and syncing you'd better get a professional cable.

cheers, Tom

Hi,

thanks. I´ll try a 110 ohm. Will be back and report - close the thread hopefully

Actually, S/P-Dif is 75 ohms, AES/EBU is 110...

... and I got that advice from a 'professional' store where I asked for a S/PDIF cinch cable

tnx Kim,

Tom

If you want to use sp/dif in you have to physically unplug sp/dif out.

For all luna/pulsar users still having this annoying problem with sp/dif:
try a dedicated 75 Ohm coax cable (not one just reading "video cable" or something like that). I was about to forget the whole sp/dif thing, (after trying a dozen different cables, upgrading, housecleaning),
when I hooked a Deltac RG-59U cable (single) on and it worked, finally.

If it was 110 ohms it is probably a loger cable,but the AES standard as Kim pointed out shouldbe 75 ohms

What? That's not true. I have such connection for 2 years with no probs. Problem starts if you set both devices to record (or - while Pulsar slaved you set the second device to be slave to Pulsar - so you make a loop)
