Kemper - S/PDIF coaxial to S/PDIF optical - what are you using to convert?

ST · August 26, 2020 at 11:15 PM

Hi, Folks.

I'm looking at these interfaces.

RME Babyface Pro FS

and

Universal Audio Twin X

I know there are lots of differences, but both of them us S/PDIF optical connections.

What are you using to connect your Kemper S/PDIF coaxial connection to S/PDIF optical interfaces?

Thanks,

ST

I use the coaxial connection since that is what I have on my KPA. I connect the KPA to a Motu Audio Express.
It works fine (most of the time) with Firewire connected to a Macbook pro.

There are cheap S/PDIF coaxial to S/PDIF optical converters but I don´t know if they work properly.

I found this thread because I have similar considerations. I am moving to PC and I fear that Motu Audio Express won´t work.
It has a USB connection as well (not only firewire), but it often crashes.

I think this looks promising:

Has anyone had experience connecting one of these interfaces to their Kemper Profiler?

RME Babyface Pro FS

and

Universal Audio Twin X

KPA/Babyface here. If you google Linkfor bi directional toslink/coax convertor you'll find the unit I use. Plug and go, no issues so far but it is quite new. I somehow lost my old convertor (can't recall what it was) so had to buy a new one. After a few hours of research the linkfor seemed to be liked by all kinds of users including a Kemper user. Way back I bought some of those plastic silver/gold units which are all over eBay. One of 'em failed pretty early on so I wouldn't recommend those.

Hi, ajs.

Thank you.

Is this what you have?

Can you hear any difference between the digital connection compared to analog?

You need two of these units for reamping, right?

I picked up the RME Babyface Pro FS a couple of days ago.

Cheers!

Yeah, that's the one. I hear no difference between analog and digital outputs. I presume two would be needed for reamping but I don't do that so don't know. There's a checkbox in the BF software (cant remember where, I presume prefs) to sync the unit. The sync light on the BF will be constant green when properly sync'd.

Hi ajs,

Thanks for the tip about syncing the Babyface.

Since the Babyface has four analog inputs plus digital i/o, I may not need to use the digital connection. However, it's great to know that the converter you mentioned works for you.
