Using HD Omni for Stem Outputs

[aaquilato]

Hi everyone (reading along).

I've just added an Avid HD Omni to my setup. Mistake?

I'm trying to bus all 8 outputs and I'm finding that outputs 1 & 2 from the DB25 connector are, for all intents and purposes, not there.

Interfaces like this, that provide an infinite variety of options, usually fall short somewhere. I've read the manual and have been changing things on both the Omni and in Pro Tools. Nothing has brought signal to Ch1 & 2 of the DB25 connector.

If analog outputs 1 & 2 can be mirrored to the TRS jacks... why aren't they showing up on the DB25 outputs?
Where else would they show up?

The DB25 connector on the rear of the unit clearly states analog outputs 1-8.

Any thoughts on what I'm doing wrong with the i/o set up?

It works fine here. What exactly are you trying to do?

You only have 8 outputs from Pro Tools with the Omni. Period. Either monitor outputs, or line level outputs, or digital outputs.

Hi LDS.

Aside from trying to get my TRAK2 recognized in the i/o....

All I want to do it use the DB25 analog outputs. Period.
No Monitoring. Nothing.

Just all eight analog outputs. I can't seem to get the first two working.
I've been reading the manual put I'm stuck.

Those first two analog outputs are assigned to MON and I can't find the option to change them to A 1-2 and still have the other six outputs active.

It's either A 1-2, 3-4, 5-6 OR MON, A 3-4, 5-6, 7-8.

What am I doing wrong?

You just need to delete the monitoring setup. Open up the hardware window in Pro Tools (Setup -> Hardware), then click the 'monitor' tab. Under 'format' for both MAIN and ALT, choose 'none'. That should remove all of the monitoring assignments associated with the Omni.

If you then click back to the 'main' tab, you should be able to assign all of the outputs to analogue 1 through 8 in pairs. I would also double check that everything is set to 'Line (+24 dBu)' in the 'Analogue Out' tab.

If it still doesn't work, I would perhaps start looking at the physical wiring.

Thanks, I will check that after dinner.

I've already switched out the cable. Same result.

Do you have any thoughts on the TRAK2?
It has the AMBUS card, AES+ card and the 8ch DAC card.

It worked without the HD Omni.

A 192 and the TRAK2 with the mini digi-link adaptors.
Mojave 10.14.6
PT Ultimate 2019 v10 with the HD Native card. It was rocking.

Since I added the HD Omni, I can't seem to get it to work.
I have the digi-link license but that doesn't seem to help.

I've tried several different ways of stringing them together.

Thoughts?

No experience with it, I'm afraid. Does the Omni and 192 work fine together?

[aaquilato]

Yeah.
I'm just getting familiar with the Omni as you know but they play nice together.

16 analog outputs with both combined.
The 192 has 16 digital i/o and the standard 8 analog inputs.

The Omni only has AES input on XLR which is a drag.
Plenty of monitoring options but they all connected the DB25 outputs so it really isn't made for bussing stems as far as I can tell.
More for surround mixing I guess.

Yep. That was it.
Thanks for the help.
Now that all the outputs are mapped, it's on to the inputs!

This is the setup I have at home and it works perfectly.

Glad to hear. There is something inherently confusing in the Omni manual. It seems every Omni owner goes through a similar stage of confusion when first setting it up, myself included.

If the omni and 192 are working fine together it doesn't really seem like a hardware issue. My only other thoughts are to setup the Omni and Trak2, then try deleting pro tools preferences followed by a restart your system with a couple of PRAM resets upon reboot.
