Mutable Instruments Volts - +5V Power Adapter


Out of Stock

Product Description

Do I need this?

Recent Mutable Instruments modules no longer require a +5V power adapter. This power adapter is only needed for:

  • All units of Grids manufactured before january 2014.
  • All units of Edges manufactured before february 2015.
  • All units of Braids manufactured before july 2015.

The Volts power adapter can however be used to power digital modules from other brands!

Recent cases, bus-boards, or power systems (such as TipTop Audio’s Zeus line, or MakeNoise Mini-PWR) provide a +5V source, but older Doepfer cases are only equipped with +12V and -12V. To bring to your system the +5V rail needed by some digital modules, an adapter such as Volts can be used.


First of all, make sure that your case/bus board does not already have a +5V source. Doepfer cases/bus boards have 3 LEDs, one for each voltage (-12V, +12V and +5V). Power your system on and check that the +5V LED is off before installing the power adapter! Using Volts in a case already equipped with a +5V source might damage your equipment.

Your system must be powered off during the installation of the power adapter. Insert the Volts power adapter on one of the 2×8 pin connectors on the bus board. Make sure that the -12V text printed on your bus-board is on the same side as the -12V text printed on the Volts module; and that all male pins of the bus board are inserted into Volts‘ connector.

Technical characteristics

  • Maximum output current: 1.5A.
