yes - this is it. you have to connect one leg of the CR1 to the other leg of the same diode with some wire.

Or AC Line power filter:
http://en.wikipedia.org/wiki/Line_filter -
If you want to do mod - it is easy - this is not a rocket science:D
Just put the pictures of the PCB's from the inside of the AMP and I will tell you what to do.
If you want to temporary bypass just short endings one of the diodes - no matter which one.Here you go how to connect 1M pot like in JSX paralel to the diodes. You have to cut out R3 .

Thank you very much for your replies, your detail is very helpfull. The Focusrite Scarlet 6i6 is the best card for me (USB), I'm decided. The question, now, is to find my future headphones. Beyerdynamic DT-990 Pro, DT-880 Pro or Audio Technica ATH-M50? (the DT-770 Pro seems to be tiring for long sessions as a closed headphones and maybe too much bass with it). Have you got some tips for the choice?
Ihave DT150 and they are much more closed and heavy then 770 but I never feel tired with them. You have to walk to the music store and test it:) The closed headphones have one advantage - they are more quiet for the others - and you also do not hear ambient around you.
I can say they are really comfortable. -
I recently bought used M-Audio 2626 Profire (firewire) for about 190$ with spdif out/in and 8 chanell preamps. It's working fine with Kemper and SPDIF's - and had a two chanell's out for headphones. As for the headphones- Beyerdynamic DT150 will do the job:D
-
There is a simple two diodes circuit which perform nose reduction. It's should be easy to temporary disable this
Just mount switch to bypass CR1 and CR2 - and your will be happy:) Find the
diode CR1 or CR 2 and short both ends with some jumper , cable etc etc.External Content www.youtube.comContent embedded from external sources will not be displayed without your consent.Through the activation of external content, you agree that personal data may be transferred to third party platforms.

Look for crunch sound with diodes and without.1:30[Blocked Image: http://img.photobucket.com/albums/v497/Cool_Dave98/diodecircuit_zps607345b3.jpg]

It can be a lot of electronic stuff.
I have similiar sounds with PC or monitor close to the guitar pickup.
Sometimes it can be USB cable plugged to the Kemper.
It even can be your cell phone:) -
I think the Ethernet connector could be usefull for audio stream and editor connection to the PC. Ethernet is now almost a standard for studio equipment. All multichanell AD/DA converters which used fire wire now have a version with Ethernet interface. USB is not stable and have larger latency times (+limited bandwidth with 2.0 version).

well - you have to dig into the DSP theory , Nyquist frequency and IIR and FIR filters in discrete domain to know what will be the effects of this kind of experiment.
The users with 44kHz KPA may have some aliasing effects on 48kHz profiles. -
I am trying to profile an amp at 48khz. Seems to be working fine so far (still in the alien abduction phase). I'll report back after I test the profiled amp a bit.
*EDIT*
Okay, so I made a 48khz profile, and it sounds massive. It has a bit more high end sizzle to work with as well. I've also determined that pure cab's options work far better with 48khz audio (at least in my opinion) than with 44.1khz. There's just a lot more too it. I still have no clue exactly what it does, but it gets rid of a lot of the problems that I was having with previous amps, so lol who knows. As for sample rates, I would really like if mr. Kemper himself would comment on it being safe or not to leave my kemper in 48khz mode.
[Blocked Image: http://i.gyazo.com/0f75a53a862b787ceef50c435a459aa3.png]There is a problem - you cannot share 48kHz profiles with others (44kHz) KPA users.
-
Are you openly suggesting to tinker with the profiler's sample rate?
You must be crazy!
No - i think this is anacient aliens technology hidden in Kemper

This shouldn' t hurt you Kemper. The Fir and iir filters will be working on different frequencies:)But you can also overclock a DSP !!!!
I love this hidden menu:)

Regarding 48kHz - you could try to enter into Debug mode (holding system key for about 4 seconds) .
There is a parameter FS: 48 44 36 kHz;)But i think after this setting the profiles may sounds different....
-
This.
I belive this is a too expensive gear for this purposes.
Texas Instruments is offering SCR IC for only 6-10$ / IC :
http://www.ti.com/product/src4184With some on-board logic the cost will be no more then 20$ for mass product Only for 4 channel SRC .
I Think The Kemper Team could add this like an upgerade hardware module.From the Kemper site - it easy - the Kemper PCB DA/AD are connected with the ribbon to the SPDIF PCB.
The ribbon can have all necessary digital signals to interface with upgrade module. Before you plug module you can set it to the desire configuration by the jumpers for example.Please Kemper Guys -consider this case:) Especially that you can set the desired sample rate output on this IC.
I want to begin DIY project with this but I dont have too much spare time.
-
I dont know how about 44/48 sample rate but like I wrote in another thread:
Just to let you know.
The CS42435 AD/DA is used in Kemper.For me it's now clear that this is limited by hardware not the firmware.
Source: cirrus.com/jp/pubs/proDatasheet/CS42435_F4.pdf
"AUX Port Digital Interface Formats
These serial data lines are used when supporting the TDM Mode of operation with an external ADC or
S/PDIF receiver attached. The AUX serial port operates only as a clock master."
So i think slave is not possible by hardware construction.
-
The logic fallacy here is that "the amp is a registered trademark": it is not. You do not copy the amp, you copy a sound emitted by the amp. If you make a motorbike whose noise resembles that of a Harley Davidson, no one can claim you've broken a law: HD themselves tried hard, to no avail.
Agree:)
What if you change Cab in the profile for another - and resell this profile? ;P -
I still don't understand this - you all bought a device which can do a copy of an amp sound.
Someone of you want to sell an amp sound but the amp is registered trademark. So you first copying someones work and you try to resell this behind a mic and other stuff setup? Double morality i think:D Or even triple if you think that you buy a kemper becouse you dont have to pay to this all amp producers for their hard work.
I have an amp - i've buy it and i dont want to sell something that not belongs to me. I want a share with you how is my amp sounds:) -
Did you see any tube amp producer witch implement a copy protection ? Look at Bugera:D
-
Yep , the new firmware fix is working:) Led behave nicely:)
-
Try recording and walk with your guitar over the room - it's sound's like electomagnetic noise.
