Is it possible to get PC sounds, such as online backing tracks, though the Kemper headphone jack? My set up is a bit complicated as I am using the Kemper FX loop and 4 cable method to also run a tube amp into the interface and use kemper IR's and fx with it. The Kemper headphone jack blows my audio interface away as far as sound.
TIA
Yup, just take the 1/8" stereo out from your PC/laptop headphone out to the aux in on the Kemper
Auxiliary Input
The Auxiliary Input function allows you to feed a stereo signal, such as an mp3-player, into your PROFILER to play along with it. In the Output Section, the Auxiliary Input function is equipped with three mix controls: one to feed the aux signal to the MAIN OUTPUTS as well as S/PDIF OUTPUT, and two others to feed it to the MONITOR OUTPUT and HEADPHONE output. This allows you, for instance, to add an additional monitor signal to your HEADPHONE output, while the MAIN OUTPUTS stay unaffected. With the activation of “Monitor Stereo” MONITOR OUTPUT and DIRECT OUTPUT get paired as one logical stereo monitor output. The Aux In signal will also appear on both and its mix gets controlled via “Aux In >Monitor”. The auxiliary signal will not be affected by any internal effects.
You will need to purchase a special cable which provides the stereo signal via two separate TS jacks. Plug the left jack into the RETURN and the right jack into the ALTERNATIVE INPUT. Use the "Aux In >…" soft knobs to adjust the level.
Thanks for the help. I am using the Alternative input and the Return currently for the FX loop to the tube amp I am using. Si I assume this will not work?
Thanks you for the help.
Rats... I should have realized that from your post.
Can you use mono effects loop, and mono in for the PC?
K - wait a sec- I don't understand something - you're using an AMP in the FX loop? Why not profile the amp as a direct profile instead?
Yeah, I was hoping you could use Alt/Return as mono, one in for the effects loop, and one for the PC
So just get a single 1/8" to 1/4" TS cable go from PC to Alternative input and it may work?
Not sure. When I tried it I had a stereo 1/8 to two 1/4 cable, and it worked a treat for mixing PC and Kemper.
What I haven't tried is splitting the inputs for two different purposes.
Well it looks like firmware update 5.5 added Aux in - mono" so it should work me thinks?
I guess you're a couple of bucks away from trying.
Stereo 1/8 PC side to mono 1/4 to the Kemper.
Best of luck and I'm very curious to hear!
I think I understand your setup but it doesn’t make proper sense to me so I might be missing something. Could you draw little signal path diagram?
How are you getting the final valve amp sound into your interface? Are you using using a mic, a loadbox somewhere in the chain, or taking the signal from the FX loop of the amp only (so no power amp involved)?
When running the real valve amp are you placing this in one of the slots A-D and turning off the Amp section in the Stack Block or layering to different amps on top of each other?

Very bad idea. you need a little console or mixer to take care of that. Plug your computer outbut and kemper output to the mixer and THEN listen to the mixer headphone output. Dont try to cut money on that you'll end up with bad results just to save some$
OK. i didn't realise it was an H&K with Built in Load Box. That makes sense now.
Unfortunately, I don’t think you are not going to be able to run backing tracks through the Kemper and use the KPA headphone out with that setup.
However, I don’t quite follow your signal chain as listed above. I doesn’t make sense to me but maybe I’m just not thinking straight and am missing something obvious (it wouldn’t be the first time 
).
In step 2 you seem to be running the KPA main out (?) into the FX return of the H&K. Is that correct? In this case you would alway be sending signal through the H&K power amp and Red Box even when the H&K is out of the Kemper Loop.
In Step 3 you feed the signal from the H&K fx send back to the KPA fx loop return. This would send only the H&K pre amp signal to the KPA fx return. In this case the H&K would simply behave like a distortion pedal rather than a full amp (although I now see that you would appear to be getting the power amp later in the chain but the fact the KPA is in between the pre amp and power amp is likely to affect the interaction of the two and achieve a different sound than running the amp normally).
In step 4 you send the Kemper Direct Out to the amp input. This would send the signal from the KPA to the amp at whatever part in the signal chain that you decide to make the split (place the loop fx block).
Finally you are sending the signal from the load box (with speaker simulation?) to your interface. I tried to draw out the signal path to make sure I’m not missing anything. If I understand correctly your signal always goes through the H&K power amp and loadbox before going to the interface.
Are you using the RedBox speaker emulation on or off? If on, are you turning off the KPA cab block? Otherwise you will be getting two speaker emulations before you hit the interface which would obviously make the sound from the interface headphone out very different from the sound coming through the KPA headphone out. Could it be that this is what is making you think the KPA headphone sounds much better than your interface?
If you really must run the H&K with the KPA would it not be simpler, and potentially better sounding, to just run the H&K in the Kemper loop. GTR > KPA In > KPA Loop Send > H&K In > Reb Box Out (speaker emulation off) > KPA loop return. This would let you run the KPA on it’s own, the KPA plus the H&K with the KPA Amp Stack on or H&K on its own (KPA loop active but Amp Stack off.
An even simpler solution would be to simply make a direct profile of the H&K from the Red Box and use the profile instead of the physical amp. The results should be effectively identical in sound and feel but this would free up the Aux in Stereo to run your backing tracks through the KPA headphone out.
