Rocktron PowerTap Pedal - Manual (Page 10)

Cables and Connections continued...:
1 BLACK 9V Battery snap cable to be used on pedals
that only run on a battery and do not have an adapter
power jack.
1 BLUE cable with a 2.5mm plug that allows you to
plug in pedals that require a larger or 2.5mm plug.
1 RED Reverse Polarity Cable. Please note that on
this cable the Tip is POSITIVE and the Barrel is
NEGATIVE. Please check your pedal’s specification
first before using this cable.
The PowerTAP outputs are “isolated”. It is similar
to each of your pedals having their own designated
connection to the power source. Thus, if you have
a pedal that has higher DC requirements such as
18VDC or 24VDC you can use two outputs simu-
lataneously to power the pedal. This will require a
Y-Cable that can be found at most electronic supply
stores. Please make sure you follow all the manufac-
turer’s instructions.
