Left Channel only!

Denicio · July 24, 2016 at 5:43 PM

So today when i was scrolling through profiles on my amp i suddenly lost my right channel. Zero output.
I have checked every cable in my studio. Everything is fine and my DAW outputs properly in both channels.
In a last bit of trouble shooting i plugged in my kemper headphone jack. They too have LEFT channel only. OUCH!!

I have the most current version of the OS. I even tried writing over it but when i plug in the USB stick with a freshly downloaded version (of the version i already have) nothing happens. I guess it sees i have the most current version.
I have looked at all the menus to see about Left and Right output assignments but found nothing.

Can anyone HELP me!?!?!??

Has this happened to anyone else before?

I am hoping there is a simple step somewhere that i can toggle to remedy this issue.

I really dont want to have to send this thing into repair.

Help, Thoughts, Comments?

Thanks,
Dennis in Memphis

You sure it isn't just your right ear that went out?

Did you do anything different since your last working session. Anything at all?

Welp, i started looking at unrelated issues on the forum. Saw one about crashing kemper.

A post by HSJCheppier said "Start your Profiler into Browse mode while holding down the RIG button until you se "Initialising current rig" ."

Tried it and BAM, both channels are back. Very odd.

I seem to remember there's a pan control somewhere. I think it's in the RIG menu.

Cool to see that it's not hardware issue!
Please, can you write [SOLVED] in your topic name? It can help if someone have same issue.

Same problems with headphone connection only left channel is working, tried the rig button start, still the same. Headphones are working normally, is there something I am missing... Thanks!!

I got the same problem with headphone. I tried 3 of them and I only have the sound in the left channel. When connected in S/PDIF to my sound card, I have the stereo but not with a headphone directly plugged in the headphone output. It has been a while I didn't use the headphone output but it seems to me at the beginning, it works with no problem (I bought the Kemper in 2012). Any change in parameters I missed ?

Kim_Olesen · November 18, 2022 at 4:34 PM

Are you using a jack to mini jack converter between the kpa and the headphones? Just a hunch, try another converter.

Manolo76 · November 18, 2022 at 4:47 PM

All the headphones I tried have a mini-jack to jack converter but a different one for each and they work in other situations.

My headphones go out all the time when I step on the damn mini-plug to 1/4 plug to 1/4 headphone cable extension. I just kick it again to get stereo back.

I tried again. There's a little signal in the right channel but as there is a balance knob turn at something 80% left :(. I thought at the beginning there is only signal in left channel cause the presets I have tried are at low volume.

could be a faulty headphone socket. Please open a ticket on the Kemper website for support.

Yes, I've found an old headphone with 6'35 jack so no adapter needed and same thing. I would like to know before I open a ticket if it could be a setting that changed through update that I missed. That said, my Kemper is not under warranty for a long time so I'm not sure if it's worth the price to send it for repair.

Kemper Support #1 · November 21, 2022 at 6:42 PM

there is no parameter that would allow you to pan only the headphone signal. From your description, it really sounds like a hardware issue.

Have you tried starting the Profiler while holding down the System button to reset the global settings? If the issue was caused by a software condition this would probably fix it. If not use the contact form if you want to have the unit repaired.

Manolo76 · November 23, 2022 at 7:55 AM

Ok thanks. I will try the reset and will think about what I'll do. I will let you know if reseting the Global settings fixes the issue.
