HD OMNI optical inputs
 

The HD OMNI has 2 optical inputs on the back.

I have the TV plugged into one.
I have the computer plugged into the other.


The TV works. The computer doesn't. When I swap the cables, the computer works, and the TV doesn't.

Is there something I'm missing, or does this sound like a broken input?


Also, on the front of the OMNI, I'll select "IN" on the meters. 5-6-7-8 all seem to have the same input. I was hoping that one of the optical inputs would play through 5-6, and the other would play through 7-8. But it looks like only 1 of the 2 inputs is working, and it outputs to 4 channels.

Any tips on routing this thing?

Re: HD OMNI optical inputs
 

Right in the manual:

Using Optical S/PDIF (which is what TVs use) you only get 2 channels.

You only get 8 channels with ADAT. In S/MUX 2 or 4, the second ADAT is used. But you aren't using ADAT protocol in the first place.

Yeah I saw that part of the manual but its no help.

When I plug the TV into the left port, it works (while the other port is empty). When I plug the TV into the right port, it doesn't (again, while the other port is empty).

Ideally, the TV (or any compatible source) would work in either port. And ideally, I would have 2 sources, one in each port.

The more I think about it, the more im convinced that I have a busted port. I just hate to admit it.

I've not used the Omni but for both ports to be usable, there would have to be 2 stereo S/PDIF paths configurable in the hardware setup. If there's only 1, then only 1 port is usable and the manual is unclear.

There is only one. (what I was trying to point out earlier)

The lack of clarity is "either" in the manual but it should actually only be port 1.

Re: HD OMNI optical inputs
 

In addition to other comments, are you aware that the OMNI can only USE 8 IO at a time?

Yep, I understood that. Just trying to help the OP put 2+2 together and not conclude that his interface is faulty.

Here's a pic of my Hardware Setup.

And here's what's happening:

left port (while the right port is empty):
- I plug in the TV. It works.
- I plug in the computer. It works.
(In both of these situations, on my VU meter, channels 5-6-7-8 are working when "IN" is selected).


right port (while the left port is empty):
- I plug in the TV. It does not work.
- I plug in the computer. It does not work.
(In both of these situations, on my VU meter, channels 5-6-7-8 are NOT working when "IN" is selected).

Do you have a screen shot of the mixer you can share?

In your picture, you have the same input selected for channels 5-6 and 7-8. If there’s a 2nd S/PDIF available, it has to be selected in one of the input pairs.
