Hello,

I have a KN6000 but I believe the capability of the KN6 and KN7 in regards to your question is the same. I doubt the amplifier in the KN7000 (or KN6000) could drive external speakers. One solution would be to use the "line out" output from the back of the keyboard and plug it into the "line in" input of a speaker system that has a built-in amplifier. Alternatively, you could do the same using a stereo amplifier and connect speakers to it.
