I have attempted to profile a Peavey 6505+ 1x12 combo amp. I believe I have the connections correct, guitar to Kempter input, Direct Output/Send to the amp input, an SM57 in front of the amp connected via XLR to the Return Input. I switch the profiler to Profiler set the output volume select next, select clean and no cabinet, press next and select start profiling. I can hear the spacey noises coming out of the amp. Then the profiler errors out with a statement such as there is no amp connected or the volume is too low. I have turned the volume up to near full. I've checked all the cables are in working condition. I even switched mics to rather sensitive condenser mic, and I get the same result. Any ideas on what I might be doing incorrectly?
This is a Kemper lunchbox, non powered model with software version 5.3.1.13085.
