Burkhard - my question wasn't if I can turn the power amp off and on. I am aware of that. My question was whether it is that switch alone, or other settings to make the powered Kemper behave the same as an unpowered Kemper for recording, etc.
If I wanted to use the powered Kemper the same as I do with the unpowered (studio monitors, spdif into audio interface), is it a simple matter of turning off the power amp switch in the output section and using it just like an unpowered?
