This is a guide to understanding what your provided Lightning - Mini-DIN does when it's connected to your Evermix MixBox. The cable is very expensive and needs to be looked after very carefully.
The cable is designed to allow audio data to be transferred from your MixBox to your device but not only that it draws power from your device to allow the MixBox to function.
