I just connected my profiler to my Dr. z z-28 to profile it (my first profile). I connect my SM57 mic to the proper Return jack. Then, I plugged my amp to the Direct Output/Send jack. I plugged my guitar into the kemper input on the front.
I DO NOT have a mixer. Do I need one?
The first couple times I tried to begin profiling, I got the error message about amp not being connected or volume too low. When I flip back and forth between the reference amp and kemper the volumes coming out of the Z-28 cab seem to be the same level of volume. The error message came up a couple more times, so I just twisted the Return Level knob to the right (just to some random position) and it appeared to work and the kemper profiled the Z-28.
I have no idea why the error came up and what I did to solve it. Can you please explain it to me and go easy on me...
