Ground Control Pro

Power supply information taken from the forums:


The power jack on a Ground Control Pro is a 2.5mm x 5.5mm Barrel. The Ground Control Pro comes with a 9VAC @ 500mA power supply, but it can be powered from 9V AC or DC source (polarity doesn't matter).

You want a power supply that can provide 9V AC or DC with a minimum current rating of 500mA.

Any Voodoo Lab dealer should be able to get you the appropriate power supply, but most won't likely have it shown in an online store.

Alternatively, you can give us a call or write to [email protected] to order the original power supply directly from us.

I hope that helps!


We have always used a full wave bridge rectifier setup on both the 5.5x2.5mm barrel connector and the Phantom Power input (pins 1 & 3, as well as pins 6 & 7, of the MIDI Out jack). A full wave bridge rectifier will accept AC or DC power, regardless of the polarity when using DC.
