I wouldn't bother with a mono adapter. If I read the KIO3 schematic correctly, the K3's back-panel microphone connector and Line In connector are stereo jacks with only the tip wired.
I think the damage you refer to might have been from a mono speaker plug that shorts one side of the speaker amplifier to ground.

However, I have a question about the mic connector. It's a stereo plug (why I don't know except to perhaps make it more compatible with a PC sound card) and the mic input on the K3 is Mono. Should I use a mono adaptor or not? Doesn't seem to matter but I am worried about possible damage to the K3 since I have heard that at one time that mis-match was a problem with the Line In connector.
