spdif newb

Hey all,

I've been going spdif out of a dbx 386 to my stock 002r spdif in. I'm using half of one of those red and white ended rca cables, and it seems to work fine. I recently bought a BLA modded 002r, and when I tried to connect my dbx 386 the same way as before, I got no signal on the spdif L and R tracks. Channel 2's analog output on the dbx doesn't work, which is why I've been using the spdif out.

Am I even using the right cable? If not, is this likely the issue?

The dbx also has AES out, but the 002r doesn't have an AES input, if there even is such a thing. Is there some kind of AES->spdif adapter?
I don't have my stock 002r anymore, so I can't just do a quick swap and see if there's a diffrerence.

If you haven't guessed by now, I'm completely lost.

Thanks,

C

Sounds Like your using an analog cable with a digital I/O port.

Get a better cable and make sure its digital SPDIF 75 Ohm.

Analog Cabling will not work with digital signals,
However Digital cabling will work with Analog signals.

Have you checked the "Hardware Setup" dialog in Pro Tools to be sure that the SPDIF input is still enabled?

Analog cables will pass digital signal. Just not very well. As Adam said, you should make sure you get some proper 75 ohm digital cable. However if you're not getting any signal at all, you probably have an issue with your Pro Tools set up.

Like cory said, check your hardware setup, to make sure that s/pdif is set to RCA and not optical. Also make sure your clock is set to external s/pdif. Note that PT will refuse to change the clock source if there is no cable plugged in, or if the cable is not working properly, so that is a good test.

Then go into your IO setting and make sure that those inputs are active and routed properly.

Try those things and let us know how far it gets you.

As far as the AES port, AES and s/pdif are very similar signals, and you can get converters for them so you can plug AES into a s/pdif port, but you have no need for that unless you need to do some long cable runs.

Hope that helps.

yeah, check your settings cause you would still get signal with an r.c.a. cable, i've used them before, they work, you would at least get clicks and pops...if your getting nothing, its your settings or a faulty spdif input.

So it was a hardware setup thing, fixed now. I grabbed a Planet waves 75-ohm rca cable, but it doesn't say spdif or digital anywhere on it. Did I grab the wrong one? Sorry if that's a stupid question.

Thanks,

C

An RG 59 video cable with 75 ohm BNC or RCA connectors will work well too.
