Connects to one of the pedal inputs on the unit or remote. No experience, but it's a well-built two-button footswitch.
From what I've seen regarding the footswitch, it can be used as an extension of the Profiler Controller, or as an extra few footswitches on a Kemper Profiler Stage. Basically can be used to turn on and off stomps, turn on and off different parameters, and to go up and down performance banks and stuff like that.
Not 100% sure about the specifics though. Some more research into how it can be used might be beneficial. But if you're looking for some way to add more footswitches to your Controller or Profiler Stage, this seems like the way to do it.
I believe it connects with a TS or TRS cable to the Profiler or Profiler Stage. I'd check online for a manual though, to be sure.
Best of luck!
go into the System Menu and navigate to one of the Pedal Input pages. Select Kemper switch and turn the knob under A or B. This will show you everything that can be assigned to it.
