Capture with loadbox not working

I’m trying to capture my Revv D20 Amp with the integrated Two Notes loadbox. I am following all instructions of the wizzard and I’m not getting a signal at all in the Device In2 and I’m out of ideas. What am I missing?

Here’s what I did:

  • Guitar → QC Input 1
  • QC Capture Out → Revv D20 Input
  • Revv Loadbox Balanced Out → QC Input 2 (with a XLR)
  • Headphones in QC Headphones
  • In type 1 = Instrument
  • In type 2 = Mic (no phantom power)

checked all cables and scenarios of the chain. All works - just not the signal from the Revv Out to the QC In2 (cable is fine).

Is it something with the fact that I’m using an XLR cable or smth?
