12V and 9V Eurorack Power Converters
As addition to the DSQ-1 and DR20 the two power converters connect the devices to the 12V Eurorack power supply. It abolishes batteries or external power supplies which are usually used to power the devices.
USB power converter
Just connect the Eurorack connector to the Eurorack power supply and plug in the USB cable from the Korg SQ-1 (or any other USB powered device)
9V power converter
Disconnect the cables from the RE-20 battery holder and solder them onto the small PCB. (Pay attention to the correct polarity) Although pre-configured to 9V, the converter power can be freely adjusted for other devices to any voltage below 12V.
