Topic: ADAT1 Not Outputting

Hello,

I am new to working with RME products, so forgive my ignorance. I have a Fireface UFX+ in my lab that I am attempting to use in an experiment. I want to use the ADAT1 output to connect to a headphone amp. Both the Global Level Meter screen and TotalMix show there is signal being output from the ADAT1 channels, but the headphones do not actually play the signal. The signal plays clearly when the amp is plugged into the ADAT2, but I cannot use that since it is needed for SPDIF in the experiment.

I assume it has to do with channel routing, but I am not sure what the best approach would be. Any insight would be greatly appreciated.

Thank you,
Andrew L

What headphone amp does have an ADAT input?

It's a Pro-Ject Pre Box S2 Digital that I connected via fiber optic cable.

No .. on the UFX II / + only ADAT2 can be set to either ADAT or SPDIF protocol ...  ADAT1 "speaks" only ADAT protocol.
And this seems to be the problem, your headphone amp does only support SPDIF.

The RME ADI-2 Pro is more flexible, it supports not only SPDIF but can also pick the two channels out of an ADAT stream ...

That's an interesting feature I've missed. Thanks for pointing it out!

Thank you very much, Ramses! Is there any other solution to this? I need both the headphone amp and SPDIF outputs for the experiment, and I don't believe my lab will support the purchase of another RME.

Thanks,
Andrew

Re: ADAT1 Not Outputting

Maybe this one

https://www.thomann.de/de/lindy_audioko … igital.htm

Its not 100% clear from the description whether it really converts 8ch ADAT (optical) to 2ch optical SPDIF.

Pls check with Lindy ...

Re: ADAT1 Not Outputting

Excellent, I will look into it. Again, thank you so much. I very much appreciate your help.

Re: ADAT1 Not Outputting

As I said, pls check 1st .. an e-mail back and forth is less effort compared to buying, testing, sending back ..

Re: ADAT1 Not Outputting

It is 100% clear from the description that this unit does not convert ADAT to SPDIF. What is misleading is the wrong description in the first user review, where such a conversion is stated, although not ADAT as format but ADAT as optical output (with SPDIF signal as content) is meant.
