I opened a ticket, anyone experience this? Issue has been fixed

    See that's the thing though, I'm not doing anything different than I do in real life, I use the screamer now limited and have to dial the gain lower than I would use on the real amp. I only gave up on fractal because of the contanstent in the dark tweaking, but that unit is maxed on features and never has a sound quality issue as this. The kemper operates on the same basic chips and stuff with less offerings and had these issues, to me I came to Kemper knowing the limits in fx and even a good software for editing but now you compromise the one thing I care about, a good high gain tone.


    Through my cab and poweramp it sounds so life like but half the gain the amp can actually do in real life


    Hello @mnewse614,


    Since you are connecting your KPA to an external power amp, I am assuming this is a non-powered KPA. You have stated that your are connecting from the KPA's Monitor Output jack to the Input of your external power amp. Can you double-check and confirm that you are using a shielded guitar (instrument) cable, and NOT a speaker cable, for this particular connection (i.e., KPA Monitor Out --> External Power Amp Input). It almost sounds like you are picking up RF interference...which might occur with an unshielded (speaker) cable carrying a line level signal.


    Cheers,

    This can't be happening with many of the, oh I don't know, 50 000+ Rigs out there (including the commercial ones), or else we'd be hearing about it constantly on the forum.


    I can only speak for the past couple of years of being here, but I can honestly say that I've not heard such complaints. Even if there were some, they must've been so small in number that I've missed them somehow.


    This is why I suggest finding alternative Rigs - Profiles of the same amp if you like, that don't exhibit this behaviour. Considering the huge number of Profiles out there, it's logical to assume that there'd likely be a bunch of alternatives, both free and commercial.


    I'm only suggesting this 'cause if I were in your position, it's what I'd do. Are you prepared to have a good look around should we have no luck in solving the issue with this Rig?

    like I said it sounds amazing just I can't dial in high gain, well full gain. I have owned almost every major high gain amp and my set up never changes. I also only mention Fractal cause I just came from the ax8 before the ultra and standard, and I'm not a fan boy those guys hate me cause I'm not a fan boy and have opinions so don't think I'm trying to promote another product, but for the money invested I find this such a stupid issue. Searching I've found several of the same complaints on here, I would assume some of the complaints became new customers of another brand

    yes sound is only the kemper, it's internal that's confirmed by support and support was quick to respond to everything except:


    So is this not a product concern? In the real world that's what I do to my amp gain on head full hit with tube screamer volume max gain, I've never experienced this with amps or your competitors product

    This is not normal, and something is definitely wrong.


    The KPA can deliver obscene amounts of gain, enough to make the hardest of hard-core death metal band blush.


    Would you kindly follow this procedure, exactly, and see if this solves anything:


    ------------------------------


    Unexpected behavior

    In case any inputs or outputs don’t operate as you would expect, or you experience any other unpredicted behavior,
    the soft button “Init Globals” in the System Settings will reset most global parameters in the System Settings and
    Output Section as well as all Lockings to their default state. This way, you are always able to recover a defined state
    of settings. Your stored Rigs, Presets, Performances, and Slots won’t be impacted by this reset.

    I get this regardless of factory or rig exchange rigs, if you see in the video weird things like hitting the -12 on mains will stop the noise then I'll play and the noise comes back. Try a high gain profile like olas evenah or how ever he spells it, add a green scream 0 gain 0 volume add a noise gate to silence the swoosh and you'll hear it though headphones after you play, then hit like a 3db clean boost and it'll really come through, it's enough I would be embarrass live, oh set amp gain to like 3 o'clock

    Also Try getting rid of that converter does it do it in just with straight headphones like it does with another user? Is there any Way you can plug the same rig and guitar into another kemper ?
    Is there a music shop and or friend?


    It would not freak me out if this is dirty electricity or harmonics from mains before every one laughs
    Power factor correction and dirty electricity is a prob hmm man that would pee me off


    So you have a second kemper?, sorry if I am not reading this right


    Ash

    Have a beer and don't sneer. -CJ. Two non powered Kempers -Two mission stereo FRFR Cabs - Ditto X4 -TC electronic Mimiq.

    I have not tried that, I thought about that but I dont want to add outboard gear, its not that I am being complicated but spending the amount of money I did, and seeing Kemper offers a TS I shouldnt have to.


    This is all the Kemper again, not my house electric, cords, guitars, amps ect. No matter the set up headphones ect it does this. This is my second Kemper in 1 week cause of this issue. From support telling me is everyones Kemper does this.


    I am building patches also by ear not by eye, I am sure allot of people can say omg 3 oclock on gain is allot, in reality its not, yes I use a noise gate in reality and tubescreamer. I can get my direct main out tone to sound right but the monitor out to poweramp cab is under gain. Yes, I know that using a physical cab will sound different than the profile because the profile has a different cab, with mic and room blah blah. I dont expect to sound like the direct profile, I do expect to sound like an amp with gain. The sound I have is amazing full amp tone the issue is the gain and gain only. I guarantee to all of you, your Kemper does this also cause that what support is telling me. Again, I am not building a tone I do not use with real amps or another type of amplifier modeler. With gain I do expect noise, thats the nature of the beast but that high pitch in the video is not right, also why when hitting buttons like -12 main out will the sound disappear but to come back when played? This is an internal limitation, what I dont understand is other devices do not do this and seems with all effects and everything they are really hitting cpus hard, but the Kemper is so open that their cpu can not be really overworking so to speak. All I need this unit to do is the gain setting with no noise and I am 100% on board. Again listen to the video my tone is not exaggerated gain it is in fact real world sounding gain.

    Dear Matt Newsome,



    please send a complete backup of the error situation. I can see on the video, that your gain is at max. I would like to see, if there are other parameters maxed out. Do you experience the same issue, if you disconnect the power amp and just monitor via headphones?

    Yes same issues through all sources, I'll send a back up, but on the profile I didn't adjust the gain only add a green screamer, this is also on factory presets as well

    to support
    Ok upgraded firmware noise still there, lowered gain noise still there but lighter



    Just to give the back story, I ordered my kemper while guitar center was out of stock, I got the first unit last week and had this issue, I tried multiple amps, monitors, guitars and cables. I took the unit to guitar center to try different cords, guitars etc and the same noise still there, so we exchanged for this unit which just came yesterday afternoon immediately hooked it up and got the same result

    Dear Matt Newsome,


    I guess, this is normal with your settings. I can reproduce that tone with your Rig. The Volume of the Green Scream is also at max. Somewhere there is a technical limit. I suggest the controls to a level where it works.

    So is this not a product concern? In the real world that's what I do to my amp gain on head full hit with tube screamer volume max gain, I've never experienced this with amps or your competitors product


    I need a solution before I return this unit. I am using a high gain profile from rig exchange that has high ratings and no issues, I add the green screamer with gain 0 tone 6 and volume 0 and still get that noise, this is not useable and very disappointing




    No response yet, I want this to work I love the unit, this seems as a huge design flaw or they did have some QA issues and not telling me right, but from their response the kemper can not take and again try these setting. High gain profile a EVH, 5105, MESA, COBRA, ECT, set gain to 3 oclock, add a noise gate 4:1 i set my thresh a 5.5, add a tubescreamer gain 0, tone 6 or whatever, and volume even at 0. You can use headphones now play, after playing turn the volume up youll hear it. Now the volume is at band levels and its very dominant not so much at lower levels, but then at lower levels add a lead boost of something that raises that high pitched squeal you hear when cranking the volume will start to be audible at lower levels, its like that sound is there constant but not audible until the signal is boosted

    I really want help here, if you can not or do not want to download the back up here is the set up to try:


    rig exchange:

    COBRA FRAMUS COBRA Marshall 1960 Tom South 4.00 / 5.00 2015-02-05



    Then add a noise gate 4:1 in the first slot, second slot a green screamer so you can find the noise quickly the green screamer gain 0, tone whatever i like 6, and volume +5, now play for a min and stop, if you dont hear it real bad turn the volume up some without playing, once you can hear the noise youll never un hear it, then lower the volume to say 0 on green scream, play and listen. This can all be done through headphones, again I use EMG so my clean sense is -6 and distortion sense is 0


    This is killing me cause again I love this unit so any help would be great, support tells me this set up gives them the same issue

    Out of curiosity, what happens if you dial back the Green Scream to 0?


    Others can chime in if I'm wrong, but I'm wondering if you're issue is a volume/level overload internal the KPA. The input and output LED's measure the very front end input and the final output. But if you start cranking up volume settings (signal level) internally throughout various stages, I'm guessing this may be creating an overload at some point internal the to KPA. Volume is different than "distortion" both of which are often associated with "gain" depending on what stage and parameter are being tweaked. I haven't tried this yet, but I'm guessing if you added some stomps like GS and Boost and cranked the volumes, and then also blasted the Amp stack volume setting, you could still lower the final rig volume and both the input and output LED's would appear happy. But between the input and output of the KPA, you'd probably be overloading something.
