Just thought I'd share this tip from a first time Kemper user...
Took my power rack to my first rehearsal. Set it all up and....no sound!
Checked the link into the cab, all ok. No signal on the input...so swapped the lead.
No difference.
Swapped guitars, still nothing....now getting worried...
Asked the other guitarist to have a look. He suggested....
....that I plug into the input and NOT the headphone socket.
Funnily enough it suddenly worked...
Do I feel like a donkey?
