When I started using the Kemper I turned down the main output to -20 db and also selected the -12db toggle in the output section (reading around I didn’t want to give too much signal to the sound desk playing live).
I have run this for a while; however, my last sound guy asked for more signal and wasn’t happy until I turned up to -3db (with -12db toggle switch still selected.)
any thoughts on best practice here? Should I even be using the -12db switch?
thank you
