Voodoo Lab Pedal Power AC
The Pedal Power AC provides two 9VAC and two selectable 9VAC or 12VAC outputs. Features include a toroidal transformer and completely isolated outputs to insure noise free operation. It comes complete with cables and detachable AC power cord. And like all Voodoo Lab products, the Pedal Power AC is hand made in the U.S.A.
The Pedal Power AC is manufactured to operate from a specific supply voltage. There are three different models which accept 100V, 120V or 240V mains. All units sold in North America are for 120V only. You cannot operate a 120V Pedal Power using 240V power without the correct step down transformer. The supply voltage is marked on the bottom of the unit.
The Voodoo Lab Pedal Power AC is the finest power supply available for AC powered
guitar effects and accessories. It’s the only professional solution for powering vacuum tube
overdrives and effects, MIDI footcontrollers, and high current digital processors--without
cumbersome and noise inducing wall warts.
The Pedal Power AC provides four isolated outputs, two 9VAC and two selectable between
9 and 12VAC. Each output is short-circuit protected and completely isolated. This insures
reliable operation, free of hum and noise.
Please take the time to read this entire manual before operating your Voodoo Lab Pedal
Power AC. This will eliminate the possibility of damage from improper usage. You can also

The U.S. model (120V input) can operate from 50Hz or 60Hz mains to allow use with a
step-down transformer in 50Hz countries.
System Unit Description
1. AC mains auxiliary. Note the 200 watt maximum rating.
2. AC mains power input jack. This is a standard “IEC-type” connector.
3. Power indicator. This LED indicates the Pedal Power AC system unit is operating.
4. 9VAC output jacks (2). Each output provides up to 600mA.
5. Selectable 9VAC/12VAC output jacks (2 sets). Use either jack from each set to select the
correct voltage. Each output provides up to 1200mA.
AC vs. DC
“DC” stands for Direct Current. This means that the flow of electricity is always in one
direction. DC power connections will always have a polarity (like “center negative” or “tip
positive”) because you need to specify which direction the electrical current should flow.
“AC” stands for Alternating Current. This means the flow of electricity alternates, first in
one direction, then back the other way. Since it always goes in both directions, there is no
polarity and the plugs can’t be wired backwards.
C AUTION: The Voodoo Lab Pedal Power AC should only be used with devices that require
AC power. The device you’re trying to power should be clearly marked as needing 9VAC
or 12VAC. If it isn’t, you need to verify its power requirements. Attempting to power a
DC operated device with an AC power source can cause permanent damage!!
The Voodoo Lab Pedal Power AC has four outputs and six output jacks. These accept barrel
type connectors and have a 2.5mm center pin.
The two individual 9VAC outputs on the left will provide up to 600mA each.
The two pairs of jacks on the right will provide up to 1200mA each at either 9VAC or
12VAC. Select the correct voltage by using the corresponding jack. You can’t use both
9VAC and 12VAC from the same pair at the same time. It won’t work. Don’t even try.
Generally, the power requirement marked on the device matches the manufacturer’s
supplied adapter. This does not indicate the actual current used, only the maximum available
from the adapter. Often the same adapter is used for many different products.
For example, the Line6 modeling pedals are marked 1200mA. In fact, all models as of this
writing draw less than 200mA.
As long as your device requires AC at 9V or 12V, just try it. You won’t damage anything.
