I tried new settings out at rehearsal last night. I reduced the main output volume to -20db to get to unity level input on the mixing board. I guess this would differ from board to board. We rehearse with headphones, with everything straight into the board and no audible instrumentation, except for drums, course. It was the best mix and sound quality we have ever had! My bandmates and I are blown away by the rich, nuanced guitar tone coming out of the Kemper. It's so much nicer than my Marshall rig, and the speaker cabinets aren't flooding the room with sound that spills into the vocal microphones. I can't wait to try this live!
I had a similar and yet completely different experience last night at rehearsal.
We rehearse at relatively low volumes but with live amps and real drums - no headphones. Last night was my first actual rehearsal with the KPA and I was not sure what to expect. Earlier in the day I loaded a few of the free Michael Britt profiles into a performance and tweaked to meet my needs, which was mostly just assigning stomps to specific remote buttons.
I was very pleasantly surprised by how awesome everything sounded. As soon as I hit those first few notes/chords I was stunned by how huge this rig sounds and feels. I set up my Yamaha DXR10 behind me, pointing up to my ears, with the KPA rack mounted and leaning on the monitor. This rig just filled the room with great tone. You could not tell there wasn't a live tube amp in the room. It was funny to turn around and see this tiny rig back there making this huge sound.
The profiles I used were absolutely perfect. Hats off to Mr. Britt for just nailing these. I used the 3rd Power profiles and was blown away by their versatility and how perfectly they sit in a mix.
Honestly my favorite part was how realistic the KPA sounds. I did not for one minute miss my AC30.
