Some of Mutable Instruments’ digital modules require a +5V supply in addition to the +/- 12V.
While recent cases, bus-boards, or power systems (such as TipTop Audio’s Zeus line, or MakeNoise Mini-PWR) provide this +5V source, older Doepfer cases are only equipped with +12V and -12V.
To bring to your system the +5V rail needed by Mutable Instruments modules, an adapter such as Volts can be used.
It is available in both a horizontal (skiff-friendly) and a vertical version (deep case with narrow bus boards-friendly).
Maximum output current: 1.5A.
Ripple noise: max. 75mV.
