On my 2nd kemper but just tried the profiling feature the past couple of weeks. The previous toaster I had almost 2 years ago, I didn't have any issues and got some decent profiles of my DSL.

Yesterday in a studio we attempted to profile a JCM800 2205. To make a long story short, after we got a great tone from the amp and also into the control room, as soon as we introduced the kemper into the signal chain, it seems to amplify the natural high gain noise of the amp (hiss) and also seemed to add some sort of gain and make the tone more brittle/bright. We spent 4 hours trying everything you can imagine from cables, ground issues, RFs, mics, you name it. Updated with video

When we stripped everything down we found that the direct output on the kemper seems to be doing something.

Take the mics out of the question.....When we plug guitar into kemper input, then direct out to amp input, that's when the issue starts. The direct out seems to be doing something. I tried a flash reinitialize, system resets, etc but nothing solved this problem. We didn't get to take any profiles as the sound wasn't good coming out of the cab. We also tried a peavey combo that was laying around and it did the same thing.

Once I got home, I tried it with my DSL...direct out to amp input and it added a bunch of hiss to the amp and the tone got brighter. Any ideas?? I've sent an email to kemper support and am praying I don't need to send this somewhere for service as it's my gig rig and I have gigs coming up in a couple of weeks. I'm going to try to roll back from firmware 2.7.4 to 2.5 today to see if that does anything.

My question now is, should the kpa be adding extra noise or volume or should the sound remain the same as if the kpa wasn't involved in the process? Again, taking mics out of the equation and just going by the sound coming out of the cab/speakers. I tried my DSL on the green channel with a decent amount of gain...without the kpa, the hiss is barely noticeable, when adding it in, the hiss is very prominent.

Did you try the ground lift on the back of the KPA?
 
Tried the ground lifts many many times. That issue was sort of solved (the radio interference). The big issue is the direct output is adding volume or hiss or noise or gain or all of the above. I'm at my wits end.

This morning I rolled back from 2.7.4 to 2.5...didn't help. I then went up to the beta 2.8...didn't help. I tried starting at the initialized rig...didn't help.
 
Gotta be something up with your unit. I too bought a second Kemper and the profiling was easy as pie with no added noise or change in tone. Good luck.
 
It shouldn't add anything, it should sound as if you are straight into the amp itself.

Check:
Output>pg1 Direct Output is set to Git Analog

Pg2 Direct Volume -27

Yeah, changing the direct output to anything doesn't change the hiss at all. Nothing changes...
 
Yeah mine doesn't add any additional noise either. Something doesn't sound right. Is your return input too hot when you're profiling?

Not at all, the output and input show a steady green. I can't even get to the profiling stage yet because of the changes that happen.

Have you backed up your profiles? Maybe you need to go reset everything to default factory settings or something?

Did all that...I did a system reset, flash re-initialize which basically wipes everything, tried different firmwares...nothing seems to be helping.

Yeah I'd call Kemper. That doesn't sound right.
 
I sent an email to support yesterday but haven't heard back. I also have an exchange set up with Musicians Friend if this doesn't get sorted out.

yeah I heard the Kemper support is great. They'll get back to you eventually.
 
New update: I'm getting an exchange from Musicians Friend. Kemper asked for a backup and so far they haven't figured out the issue. I'm guessing it's hardware.

Glad it is working out for you Rich. I would have gone the exchange route too.
