Amp Factory Mark V problem

Todd78 · Feb 20th 2014

I have some problems with the Amp Factory Mark V profiles. Decreasing the Gain leads to an increase in Volume. The behaviour is very strange since I never had it with other Rigs. The TAF Diezel Herbert or Mark II profiles work without problems... Is it a KPA issue or could it be that there was a profiling problem with the Mark V?

Sorry, I’m just back home at the end of the week and cannot tell if it‘s a problem with all TAF Mark V profiles. I noticed it at least in the Hi Gains.

Thanks,

Todd

Hi Todd. Check the Clean Sense and make sure it is locked.

Hi - I have locked the Clean Sense always at 0 db. But with these profiles there is something weird - like I wrote, as I turn the Gain back it gets cleaner, but louder and louder. I don't have other profiles that respond this way.

Do you have any stomps in the chain? I have found some rigs where using a Distortion as an OD has the same issue, but it's only some rigs - not the norm for sure.

I also find it odd that those Mark V profiles have tons of gain around 5-6, whereas I usually need to set Gain to 7-8 to get the equivalent amount of distortion on other rigs.

Do you also have the TAF Mark V or do you mean other Mark V profiles?

I'd say there are no activated stomps in the chain, but I'll check it after I'm back home on Saturday.

Hi guys - so I checked it out again! The problem appears with all Drive* and Lead* Presets. The Gain of the Profiles is always around 3, but they seem to have more Gain if you hear them. No stomps activated, just Reverb. I turn Gain down to 0 and it gets louder as it gets cleaner. I think those TAF Mark V profiles are in some way corrupt or Kemper can not handle them - I don't know...

Hi
Is there any eq with a volume boost? Or maybe a volume boost in the reverb?
It seem to me that "loud profiles" react differently to clean sens

No. I mean, there are some stomps and post-processing in the slots, but everything is deactivated.

Even when I delete the stomps completely it's still there.

For a test a changed the cab, but the problem stays.

It might be a way the kemper interrelated this amp profile.

The Mark* series of amps are always a nightmare due to the zillions of configurations.

Under the AMP section is the compressor part active? (put it back to zero if it is)

Also, there has been a few other problems recently, but this is a bit of a curve ball.
Press and hold "RIG" then disable parallel path.

I will check this out later when I get back.

I did a test case with profile "AF5-Mark V Drive":

1) I eliminated all STOMPS and EFFECTS
2) I switched off EQ in the STACK section
3) RIG -> Parallel Path is switched off
4) AMPLIFIER -> Compressor is 0.0

...ah, and yes - it is still there - turning down the GAIN it gets louder and cleaner until the OUTPUT LED lights red...

Todd, I was referring to the TAF Mark V pack. Compared to all the other Mark IV/V profiles I have, including two other commercial packs, there is more distortion to this pack at the same Gain settings as the other packs/profiles.

Quitty did a review of this pack in another thread and said he needed to set Clean Sense to -12.

Todd78 · Feb 22nd 2014

Thanks meambobbo! I tried the hints and I also changed the cab. It's much better now, but I wished I could turn the Clean Sense to -15.0 db for this Rig.

Maybe we could give this profile to Mr. Kemper for debugging the KPA source code with it

Btw, I love my KPA - best device I've ever got for my music thing! No complains, just trying to understand it better.

CK has entertained the idea of expanding the minimum Clean Sense setting. I have also noticed some rigs just don't behave correctly regarding volume. See this thread: Overdrive Stomps RIDICULOUSLY LOUD = UNUSEABLE?

Thanks, I'll read it!
