The 1U XY IO from Intellijel is a link module that connects to various Intellijel modules and cases to expand them with inputs or outputs. If it is connected to a Mixup this receives an additional stereo input. Connected to the Palette 62 Case or the 7U Performance Case (or one with Audio Jacks 2.0 Board) these get a stereo loop-in path that brings the audio signal to the large jack outputs. If the 1U XY IO is connected to the 1U Pedal I/O Jacks the large inputs and outputs are supplemented by the two small ones.
