Sounds good. Thank you.

Hey, might be slightly off-topic but would anyone be able to help with suggestions on the best way to pack a Kemper PowerRack that's inside a 6U SKB Rack Case for shipping ? I'm about to sell mine and was wondering how to do it since I bought them new and they came in shipped separately on their individual boxes.

Any tips would be appreciated.

Thanks in advance.

Thank you! I believe your suggestions pointed me to the direction I needed.

I'm now a lot closer to a similar tones between the direct Stack and the reamped version. Two things which are apparently making a difference are tweaks to the Clean Sens when recording and Distortion Sens when reamping. Plus, I just learned I can save those settings as presets. Sweet!

I suspect this is a problem with input/output levels, but I'm not sure exactly where the problem is.

I'm recording via the S/PDIF output and using the Git/Stack option: on my DAW, one track is recording the DI and another one is recording the Stack.

My issue is that the original Stack signal sounds very bad compared to the reamped version. I would hope they would sound very similiar, if not identical ?

When I reamp the DI signal (interface output -> Kemper Return -> Kemper S/PDIF -> interface input), it actually sounds good. This leads me to think that:

a) The signal going from my DAW to the Kemper and back is fine.

b) Something is off somewhere along the signal from my guitar to the Kemper and into the Stack output to the DAW.

I must mention I am using active pickups, so the signal is coming hot from my guitar to the front input of the Kemper. I've tried adjusting the clean sense (-5dB) in order to account for that.

Any thoughts ?

Here's an audio clip (first one is the reamped version, then the Stack version and finally the DI)

Appreciate any help!

Upon a submission error, the form will reset the image uploader to blank. This forces us to re-attach an image every time there's a form error. I'm not sure if it also happens with the second file uploader.

I have the same soundcard and it took me MONTHS to sort this issue out. I was correctly setting the S/PDIF clock source and sample rate on the Focusrite Control software, but apparently that wasn't enough. I was still running into the issue! What finally solved for me was setting these values via the "Audio & Midi" options on my Mac.

I posted about it here Very rare crackling in recording with SPDIF

The SRV profiles from Texas Blues Alley the best free ones I've found https://texasbluesalley.com/ol…ear-index/kemper-profiler

What project_grudge said is exactly what solved my issue!

For future reference, what I had to do on my Mac was go to "Audio MIDI Setup" and make sure the "Clock Source" option was set to SPDIF.
One thing to keep in mind - revert this option when you turn your Kemper OFF, otherwise, you might not get audio from the interface.

Thanks for the suggestions and happy to hear your issues were solved, Arhta.

I still can hear the crackling even when listening through headphones plugged directly to the interface, so I'm not sure if it's a computer related issue.
