The K-3 Mini is a K-3 box with no transmit capability. Its used with the K-3 remote system and replaced the K-0. This component plugs into a regular wall outlet and provides the remote user with the front panel of the K-3.
It has all the buttons and display along with a mic jack, headphones jack and stereo speakers for duel receive. A cable set also connects the K- mini, I called it the K-3 mini but its k- mini, to the microbit remote rig and this funnels all the commands and audio to a remote K-3 either on your LAN or over the internet.
