Trouble with SPDIF connection

Are the connectors feeling tight on the Kemper, do they work when you give them a twist/push, and don't move anything?

On the KPA, press Output, go to page 5/7, the third dial from the left is the SPDIF clock, what's yours set at?

Any SPDIF issues I had were from my interface. After rebooting the interface and sometimes PC it was all fixed. Nothing has happened in awhile for me. Mainly after windows updates

+1 - seriously!

May be unrelated, but my SPDIF connection at the KPA end has always been unreliable.

Several different interfaces and good cables.

Very often if I move my KPA or the cable just a bit, the signal dies. I have to push it in hard and twist it to get it to work. Once it is working, it works until either the KPA or the cable is moved.

I put it down to a poor SPDIF socket.

Can you post a short vid Cederick ?

Cederick, some troubleshooting steps to figure this out:

1) Is your system locking to your Kemper clock?

2) Have you tried a system reset to see if the problem goes away?

3) I know you have tried different computers, different cables and interfaces. Could you also find some other SPDIF device, or better yet, someone else's Kemper and see if it is working or not?

The Kemper needs to be the master clock when using spdif. If you set it to slave, it won't work.

Is there any indicator on the Tascam that says "locked" or "synced to external" or something like that?

I dont move my KPA and the cables are really snug. They do NOT move, whatsoever.

And it's still unreliable and wastes my time every day just trying to get the thing to work

Just fyi, when I say move, I mean imperceptibly, not inches or cm or even close. My plug is snug (haha) and my cable quite firm. Sometimes just pushing on a KPA button can do it.

Wasted a lot of my time too swapping cables and interfaces.

The Kemper wants to be the master clock.

So, assuming you have it set that way, if you shut it off you are pulling the clock from the system and you should ASSUME the DAW and interface will freak out, at least temporarily until it reverts to internal clock (if it does)

I got a SPL Crimson soundcard and I can't choose anything like sync to spdif. All I can do is to tick or untick externally clocked in Cubase and it doens't matter if I do that or not. I works anyway. So I guess it depends with different soundcards.

I was just looking here and I do not see any settings/buttons/knobs for "SPDIF clock" (KPA power rack). I just got my KPA SPDIF -> Apollo Twin -> PC/Cubase setup for the first time yesterday, and wanted to confirm that I had everything setup correctly. I'm successfully tracking into Cubase via SPDIF, however I am getting some very mild static/crackling on playback (monitoring sounds great, no clipping).

I haven't experimented w/ changing DAW buffer settings yet, but maybe this will clear things up.

I've triple checked my settings in Apollo console/Cubase and both are set to 44.1khz/SPDIF. Does this mean by default the KPA is "set to master", or am I missing some other setting in the KPA itself?

Output>Page 5/7 for powerhead, or page 5/6 for non-powered, should give you the S/PDIF clock, as seen in pic 2 below.

I have a Focusrite product, it's external clock source setting is set to S/PDIF, or not internal. You should see something similar with yours.
