Linking 2882 2d to ULN-8 3d as a 16 channel set up? [message #87758] Tue, 29 September 2020 09:36 Go to next message

Hi there -

I upgraded my ULN-8 to 3d with 2 ADAT + 1 S/PDIF edge-card.
I just bought a 2882 2d to use as converters for external preamps.
Both work independantly throught their own MIOConsole.

I'd like to have the ULN-8 as the master and link the 2882 to it via ADAT.
I'm trying to have them running together but the MIOConsole3d doesn't seem to get any signal coming from the 2882.

Is the problem coming from a 2d/3d compatibility?
Is there any way I can make it work w/o upgrading the 2882 to 3d?

Thanks and best,



Pierre

It works the other way around with ULN-8 slaved to 2882 as the master. Everything running into MIOConsole.
So it must be coming from MIOConsole 3d right?
I mean it'a bit of a shame using 2882 as main unit when you have ULN-8 at your disposal...

Thanks again,


Pierre

Can you loopback audio on the 2882 ADAT? Does that give you signal on the 2882 input?

If you are getting signal when you loop back the 2882 to itself, then all the routing and output on the 2882 is working.

If you don't then there is either a problem with the 2882 output or the routing on the 2882.

If you can get the signal looped back, then reconnect the 2882 output to the ULN-8 input.

In the Digital I/O... status, is it locked to the ADAT?

Thanks for your help.
I can loop back audio on the 2882 ADAT which gives me signal on the input. Output and routing seem fine. On MIOConsole 2d.
When I go back to ULN-8 ADAT 1 In from 2882 ADAT Out throught MIOConsole 3d with Digital I/O locked to Edge ADAT 1 I can't get any signal.
To get Input Lock go 'ADAT Wild' I have to sample rate down from 48 to 44 on ULN-8 as 2882 won't lock to 48 via ULN-8.
Any further help?

So, you have a green light in the Digital I/O... and you are clocking the ULN-8 from the 2882 ADAT?

If you get the lock light, it means we are detecting the ADAT and seeing the signal.

Are you sure you are routing from the ADAT proper ADAT input?

Can you post a screen shot of the Digital I/O status and the routing in the mixer?

To your original question, this is all trivially easy if you put a 3d card in the 2882...

Here is what I get on the Digital I/O when:
ULN-8 ADAT In > 2882 ADAT Out and 2882 ADAT In > ULN-8 ADAT Out

index.php?t=getfile&id=191&private=0
index.php?t=getfile&id=192&private=0

But still no signal coming from 2882 to ULN-8.

Well, that's a pickle. If the Digital status page shows ADAT Locked in green, that means that the signal is getting to the unit and is being properly decoded.

With the routing you have, it should be showing up in your mixer and being sent to the computer.

What happens if you do the loopback on the 3d? Do you get signal or not?
