The current guy will diagnose it for free and has quoted between £90 and £150 to fix.

I watched my last engineer spend 15 minutes testing each component on the board with a scope and a meter. He found the op amp was faulty, ordered a pack of 5 for £1.25, then I watched him spend 10m replacing it. He charged me £15.

Good luck!

Did you look at the PCB of the Kemper? Repair without schematic? 15 minutes testing each component?

I wouldn’t diagnose it for free and would never promise a fix rate for repair.

Sounds unprofessional.

I have found someone locally who 'knows his stuff' and is happy to have a look at the unit, so hopefully that will be a better option for me 🤞🏻

How much are you willing to pay for the hourly rate of the service?

And how much for the case they couldn’t fix it?

Wow. So essentially, Kemper can no longer reamp and we're all just supposed to be okay with that? That's f*ing bullsh!t.

Quad Cortex, here I come.

that’s totally wrong!

You should erase or correct this.

. I've got my Kemper connected to the Focusrite with the USB cable.

Thats wrong!

You can use analog or spiff between Kemper and your interface (without Kemper USB)

Or

The Kemper as USB Interface without your focusrite Interface!

Or

If you really want to use your interface simultaneously with Kemper USB Interface you can try to make an aggregated device (your Mac can handle it). You have to connect both with your Mac.

The first two options do work.
I did never test the third way but if you do it right it should work too.

Analog line out interface level to high? High level could be noisy.

Das hier ist ein englisches Forum.

Du beschreibst eher ungenau ein Software Problem.

Versuche es doch im deutsch sprachigen Teil des Forums hier.

Mit aktueller Firmware Version im Kemper sollte es nach meinem Kenntnisstand über USB keine Probleme auf Kemper Seite geben.

True!! I was trying to incorporate the FX of the Kemper with the actual drive of the Marshall. Thats what is being asked of me anyway.

Still no too sure of it?

I am confused. It’s not only the look? Do you have a satisfying profile for the PA? Do you use the powerd Kemper with a marshal Cab?

Do you want to use the Preamp or the power Amp distortion of the JCM 800? Is it a reissue or a modded old one (these had no effect loop)?

You can do anything you want and use any send or return, you should only know what you want.

Many many possibilities….

So, if I turn the Kone mode ON and then adjust the profiles to suit my Charvel Henrik Danhage needs, does that mean it will give me pretty much the same sound that will be sent to the mixer when playing live and connecting via XLR stereo outputs?

What I'm trying to do is achieve the best possible sound at home with the Kemper Power Kabinet to ensure that when playing live, the mixer technician gets the same sound through the XLR outputs.

Thanks

The sound at home is always different to a stage. It’s simply another room.

With main out to PC, a flat headphone (Sennheiser 650 or AKG 612) with correction of frequency and room (sonarworks) ist more comparable.

Sorry I don’t want to repeat earlier posts… it’s all said here

Why 0dB?

I intend -10 and for a mix I normalise everything to -10

Hi folks

Firstly, Happy New Year!

So a couple of months ago I bought a Kemper Stage which I love. At the moment I'm just plugging it via USB-B to USB-C into my MacBook Pro then listening to it through Garage Band.

But is there a better way to do this and to then record it? Would I be better off getting some like the Scarlett Interface then using that to record the Kemper onto my MB? And if so, which software?

What I'm worried about is Garage Band is coloring the sound.

Thanks

Your DA path of your MacBook does color the sound, your speaker, your headphone and your room does heavily color the sound.

But garage band (or logic) doesn’t Color the sound!!

Quote from Corstroe

Will the crossover also reappear for the tremolo? Thanks.

sorry couldn’t delete my post

But I agree to the point not to change the sound without pointing to changes and/or advice to the possibility how to dial in the former sound after an update

In general I love your updates and the new tremolo is unbelievable

Quote from sleshnyc

, I was absolutely able to 'boost the volume of a cranked marshall', and any other amp I was using

How many dB could you boost the volume of a cranked Marshall?

What kind of Marshall?

Without any specification I would think a Plexi. They have mainly power amp distortion.

If you boost these cranked Plexi’s, the power supply doesn’t deliver more!

Quote from sleshnyc

Did I say cranked? Did I say everything was at 10? It's like I tell my kids, sometimes it's ok just to not speak.

Sorry, of course you are right!

Quote from sleshnyc

lol. Ok. Umm. I’ve been putting a pedal in front of tube amps for 45 years. I know how they work. I can put a tube screamer in from of a Marshall and most definitely boost the volume.

No, you can’t boost the volume of a cranked Marshall!

But who cranks a 100W Marshall?

(No problem with an attenuator)

Did you profile with NAM your amp and then profile NAM with Kemper?

Or how comes the NAM profile into the Kemper? 🙃

The impedance and frequency depend output of solid state power amps is nearly not affected by the speaker as long as it can deliver enough current. Mostly they do. But I never tested it.

The over all power delivery depends of course with the speakers rated impedance

Because of the output transformer interaction it is different with tube amps.

It is really notable. I compared it with different loadboxes.

Even different types of speaker have different results because they’re impedance curve differ.

You can here it in the profile.

Should be stored in the amp section.
I make direct profiles and there of course it is stored.

This has nothing to do with the sound of the speaker. It is the interaction of speaker coil and output transformer and their impact on amp „sound“

With this in mind (Addendum 11)

„The acclaimed clean volume compensation of the PROFILER is now adjustable by the user.“

I understand it as a tool to finetune „clean sense“ for a better use of boosting pedals and/or to avoid problems with a bright cap over the volume pot

Seems not too complicated
