Moog Mavis | How do I install the Mavis in a Eurorack System?


Mavis can be removed from its case and easily installed into a Eurorack system as a 44 HP module. Mavis draws a maximum of 175 mA from the ±12 V rail of a Eurorack power supply—it does not use the -12 V rail. Ensure that there is enough headroom on the +12 V rail in your system to power Mavis before installation. 


Moog accepts NO responsibility or liability for improperly installed modules. 


To install the Mavis in a eurorack system:


  1. Disconnect external power from the unit.

  2. Remove the four black M3X8 Screws in each corner of Mavis and keep them somewhere safe. The five screws attaching the Printed Circuit Board (PCB) to the Front Panel of Mavis should remain in place.

  3. Lift the Front Panel slowly to remove Mavis from its Chassis.

  4. Look at the back of Mavis. There is a 10-pin Eurorack power header on the left side of the back of the PCB near the top.

  5. Connect the 10-pin side of a 10-pin to 16-pin Eurorack ribbon power cable to the power header on Mavis, following the diagram printed on the PCB and orienting Pin 1 (-12 V)—the red stripe on the cable—facing upwards. Confirm that this matches the diagram on the PCB—improper installation risks permanently damaging your Mavis!

  6. Connect the other side of the ribbon power cable to your Eurorack system's power supply board— confirming that the red stripe of the cable (representing Pin 1) is aligned with the -12 V orientation indicator on your power distribution board.

  7. Mount Mavis into your Eurorack system using the four M3X8 Screws you set aside earlier, or using other screws if the rails of your Eurorack case accept a different screw size.

  8. Once fully installed, you may power up your Eurorack system and begin to introduce Mavis to the rest of your system.
