New Kemper user here. Love what I'm hearing so far, but I am experiencing a consistent issue which is pretty bothersome. When I turn my guitar up anywhere pass 5 or 6 I begin to get an audible hiss that accompanies each note I play. I generally use clean to mid gain profiles. I am not getting any clipping from the input led or the output. They're always green in color. I am not doing any type of recording, but I am able to here this both through my KRK Rokit Monitors and my LIne 6 L3t. I thought I'de mention this can be heard across all profiles and with multiple guitars/cables. Any advice would be appreciated.
SOLVED Kemper is hissing when juicing guitar volume

Single coils right?
Normal. -
Hi there. Just some questions to start:
Does it change when you move around?
Do you not get this noise when you just plug straight into a traditional amp?
Does touching the bridge change it significantly?A little recording would really help.
-
What is the Master Volume setting in the Output Menu?

I don't get this sound going through a normal amp. Location and bridge don't seem to effect it. The noise is only audible when holding out sustained notes. The note plays and sustains and as it starts to die out that sizzle comes in. I will try to upload a recording sometime today.

What are your Noise Gate Settings?

I run the global gate at around 4.0. This generally seems like a good value for mid gain profiles, but definitely seems a little overkill for low gain. Would you recommend turning down the global gate and then applying an additional gate in the stomp section if need be?
-
If you are hearing it as the note does away, it may be because the Gate is starting to work. Do you hear the sound all the time when you play with the gate set to 0, or do you not hear the sound at all, even as the note dies away?
As an aside- My preference is to have the global gate set as low as possible.
-
I would try turning the gate off and seeing if there's still noise at the tail end of the notes. This sounds like something I read in another thread. I'll try to reference and add a link. There wasn't a solution in that threat tho. Could be something entirely different as well. Clips when you have time will help.

Now I feel like I'm getting somewhere. Sorry for all of the questions. When the global noise gate is set to 0, I get that audible background hum I'm used to with tube amplifiers. A value of 4.0 on the global noise gate removed that, but still doesn't touch the other sound. To remove that the gate needs to be turned up to 7.5ish. Ill be sure to upload a video tomorrow. Bare with me on this one. If the input LED is glowing green even when nothing is being played, is the signal too hot?
-
Yes - the signal is likely too hot if the input signal light is green when you are not playing. What is running into the input of the KPA?

Im using a PRS semi hollow with PRS 85/15 “S” Humbucking pickups.

Are you using two batteries for an 18 volt power supply? If so, try switching to one, for a 9 volt power supply .
I’ve seen the Kemper folks make that suggestion to bass players.

My apologies, what power supply are you referring to? The PRS is electric, so no batteries there, and the Kemper is plugged into a grounded standard wall socket.

PRS is electric
So they're not active pups, right? Meaning you do not have a battery compartment on the back of the guitar?

Post the vid when you have time. I wonder if it might be EM interference? Try separating some equipment? Otherwise a support ticket may be the answer?

What are your Clean Sense and Distortion Sense Settings?
Do you hear this hiss when you listen with headphones plugged directly into the KPA, if you are using an unedited Kemper Factory Rig?
Do you have treble boosted in the Output Menu EQ?

My clean sense is set to +4.0dB and my distortion at 0. It can be heard through headphones as well. All output menu EQ is set flat.
