The ZynAuCon module improves and simplifies the audio wiring by using a small ribbon cable for driving the 4 balanced channels (2 inputs + 2 outputs) to the 4 high-quality Neutrik TSR case-connectors. For mounting the ZynAuCon, secure the 2 x 15mm separators with 2 x black-anodized bolts M2.5. Next, you have to insert the board from inside the case and secure them with the 4 x nuts from the outside. Use a wrench for tightening the nuts, but not too much, and take care of not damaging the surface of the nice aluminum case!!

{{WarningBox|Some aluminum cases have the LEDs mounting holes a little bit bigger than it should be. For patching this issue you could use a drop of glue from the inner side.}}
    
When it's done, you have to plug the LED wires into the 2 spare "DUPONT" connectors from the MIDI harness (green & yellow wires). Polarity is important, so don't cross the wires:

Plug the little 2x10 ribbon cable on the Hifiberry's J1 connector. Next, plug the other end on the ZynAuCon board. Observe that the ribbon cable must be bent forming a 90º angle, so it fits perfectly the space and distance between the 2 IDC connectors.
