In addition to an AC adaptor, the SYSTEM-1m can also be operated on Eurorack system power (+12 V) by using the included Eurorack power cable.
* Always turn the Eurorack unit off and unplug the power cord before plugging the Eurorack power cable.
1. Insert the 16-pin connector of the Eurorack power cable into the Eurorack power connector. When inserting the connector, align it with the groove. If there is no groove, align the wire bearing the red mark with pin number 1.
2. Connect the other connector of the Eurorack power cable to the DC IN jack of the SYSTEM-1m.
* The +12 V power of the SYSTEM-1m draws 700 mA of current. Use a power supply that can deliver this amount of current.
