I have a Kemper profiler rack unpowered. My rig is the Kemper through 2 Crown xls 2502 power amps to 4 Marshall 4x12 cabinets. The issues I am having are the following: Output from the guitar I can only turn my volume about half before it completely breaks up and sounds like crap both without speakers and using speaker simulator of the unit through monitors or headphones. Setting volume levels for the unit. I use a rhythm channel at normal band volume and then a lead channel that is boosted at higher level to cut through the band live. I don't know what is happening but I seem to lose the volumes and each preset in my performance is playing a the same level. When I first started using the unit I was able to have different levels but when I try and set it up for different performances I can not recreate what I did before. I think it might have been dumb luck.
Thanks for any assistance anyone might be able to provide. I need a Kemper guru!
