Hooking up an AD/DA to 002...I'm stumped

[recall]

Hi Guys,

I managed to snare an RME ADI-2 on ebay over the weekend. It came today, and I'm having a few issues (which I think is down to the cable i'm using)

I tried hooking up 002r's optical out > RME optical in, then setting the external clock to be master. The connection seems to work, but PT rejects it saying it is not a valid external clock and that it is reverting to internal.

I tried to do the same with my Octopre LE just to check that it wasn't an RME specific thing. Same thing happened again..."reverting to internal clock etc"

So, this was my only Optical cable. I have ordered some more and some SPDIF cables as well. Hopefully that will do the trick.
If it doesn't, I'm stumped as to what to do.

I would have thought that if the issue was with the cable, then the RME/Octopre would not have "locked"

Also, I used to clock my 002 from my octopre with no problems via optical.

Can anyone shed any light on whats best to do?

You need to connect the RME optical out to the Digi 002 optical in so that the 002 can see signal (and clock) from the RME. Then set the clock source to external/ADAT optical.

Hi Cory,

Thanks for your quick response. Well I managed to hook it up like you said and Pro Tools is accepting it as master clock.

I am slightly confused by the manual though.

At the moment the ADI2 Input LED is blinking/flashing.

I'm unclear if it is supposed to be this way.

First of all I want to clock my pro tools system from the adi2 @44.1/24

after I get this working I want to use its AD side to caputure the summed mix from my summing mixer.

I want to use the superior DA of the ADI to monitor my mix

Sorry, as you can see I am confused!

at the moment my setup is like this

002r>mackie big knob>adam a7

I hope to set it up like this:

002r>suming mixer>mackie big knob>adam a7

with 002 clocked from ADI. ADI handling print of summed mix back to pro tools.

I reall appreciate the help.

You should hook up optical cables both ways.

Thanks for the advice,

I got a couple of spdif cables this morning , hooked them up and everything seems to lock now.

Only concern I have is in the pro tools "hardware page".

When I set clock source to spdif its fine, then when I try to change the optical protocol to spdif as well it won't accept it and proceeds to change the clock source back to internal.

I am getting there slowly with this!

If you are set on using optical cables. Use the shortest possible. I've had problems on several occasions that were solved by switching to shorter cables. Also, if they're long one's and if they're coiled, uncoil them. Shouldn't matter, but I've found it to help too.

I'm using 0.6m coax spdif cables.

Somebody mentioned using one optical cable and one spdif.

I'm confused by this whole thing....

^^ - to re-iterate the statement above - ^^

I'm using 2 optical cables with my 002 and Behr ADA8000 -

1 in

1 out

With optical cables, the source is not SPDIF in this setup - it is ADAT... Which means I'm getting an extra 8 channels digitally into my DAW rather than just 2 with SPDIF --- anyway, same idea - looks like the RME can do ADAT too even though just a 2 channel device
