Kemper Profiler Rack Kemper Profiling Amplifier Rack This is the model without a power amplifier. It was rack-mounted, so there are some marks on the rack mounting points, but it's in beautiful condition. I don't see any scratches. The protective film on the display is still in place. It was used only indoors in a non-smoking environment. Operation has been confirmed. The original box, various manuals, power cable, and CD-ROM are included.
