Voodoo Lab PEDAL POWER 2 - Manual (Page 6)

Connections
The Voodoo Lab Pedal Power has eight DC output jacks. These
accept barrel type connectors. Notice that each of your DC power
cables have a barrel connector on at least one end. The other end has
either another identical barrel connector (6 supplied), a 5.5x2.5mm
RED barrel (1), a 3.5mm mini-plug (1), or a battery snap (1).
Use the standard barrel connector cables with Boss, newer DOD,
Ibanez, Prescription and Voodoo Lab pedals. If you have a pedal
from another manufacturer which appears to use the same connec-
tor, you must verify that the polarity is “center negative” to prevent
damage to the pedal. This is the standard polarity and virtually
all pedals are wired this way. Exceptions are the Fulltone ‘69,
SoulBender, and Octafuzz pedals and Big Briar Moogerfoogers,
which have their power jacks wired for “center positive”. If you
have these or other pedals which require reversed polarity, see
“More About Cables” below.
Use the cables with 3.5mm mini plugs for Dunlop, MXR reissue
and some older Voodoo Lab pedals. When using pedals of another
manufacturer, you must verify that the polarity is “tip positive”.
This is the standard polarity for pedals which use the 3.5mm mini
plug for power. If you have a pedal with reversed polarity, see
“More About Cables” below.
Line6 modeling pedals, like the DL4, use the RED 5.5x2.5mm
barrel from outputs 5 or 6 only. Remember to set the corresponding
switch to the “ON” position.
If you have a pedal which has no power jack at all, but it runs on a
single 9V battery, you can still power it using your Voodoo Lab
Pedal Power. Use the cable with the 9V battery snap on one end.
This will mate with the battery snap inside your pedal once its
battery has been removed.
