When you have a new Kemper, you have two options. I have an old one, which only functions as slave: Kemper is master, the Focusrite clock is synced via SPDIF. You could also choose the other option, where the Kemper is slave (auto?) and the Focusrite clock is internal.
Make sure the frequencies match (for example both are 44.1 kHz) and you should be good to go! Check the output settings to see what the Kemper is sending over SPDIF, there are a lot of options there.
Internal is master, same as on the Focusrite.
As I said in the post above: internal is master. And for everything else, check the manual.
ReinoutV answered your question 2 times already, there's no clearer answer than what he wrote.
Kaschko: when you can read the text "internal" on the display, the PROFILER is set to "internal" (= PROFILER is master)
Connecting my Kemper to my focusrite scarlett via SPDIF.
How do I set them up correctly as master/slave?
In the focusrite I can set up the source as SPDIF. Inside the Kemper there's a setting called "auto" but once you press it the field says "internal". Should internal be marked or not? Of simpler said, should I read the word "auto" or "internal"?
Thanks!
excuse my ignorance but what is the idea to use the Kemper as master or slave?
Hey there Kemperites. Where is the setting in the Profiler/Head unit to set the SPDIF to "slave" on the Kemper? Do you need a specific OS to have this setting? I am just about ot upgrade to the new 8.0.5 OS. Thanks.
I just did the update and all seems well but when I set my interface (Focusrite 18i8 gen2) the internal @ 48kHz and the Kemper to Auto and 48kHz they both say they are locked but I get the old clicking noise. If I set it back to Kemper as the master then it works but it kind of defeats the purpose. I also tried it at 44.1kHz and it seems to work with Focusrite as the master and Kemper as the slave. What's going on here? Shouldn't it work at all sample rates as long as they match?
Power cycled both and still the same. Kind of a bummer having to switch the setup every time I want to use the Kemper with my interface. It's not a show stopper though just a little inconvenient.
What's going on here?
Have you wired 2 S/PDIF cables?
The S/PDIF cable from interface to Profiler is required for the Profiler to sync to the interface. One cable only won't work.

Holy cow I feel like a dumba$$. Thank you lightbox for steering me in the right direction. 
Why?, if I may ask. What’s the problem with having the Kemper be the master?
It's just a little inconvenient when working in my studio. I have a couple of different interfaces and the interface is always the master (I need to buy a nice mater clock but I digress...). When I want to record guitar I have to switch the SPDIF input to look at the Kemper. It's nice not to have to do that or worry about it. In the past I have forgotten and gotten pops and crackles on the tracks which is not acceptable as you can imagine. Good job Kemper!
