Connections
Pedal Power 4x4 is powered directly from mains using the supplied AC line cord.
This is a standard computer-type IEC line cord, so it’s easy to obtain a
replacement or different length.
Important: Pedal Power 4x4 is manufactured to operate from a specific supply
voltage (100V, 120V or 240V) which is marked on the bottom of the unit.
Attempting to operate at the wrong voltage may cause permanent damage.
All 9V outputs can also power ordinary low-current battery operated pedals.
(1) 9V and 12V high-current output pairs. Each pair is an isolated output section
providing up to 400mA.
Note: The 9V and 12V outputs within a pair are not isolated from each other
(their negative terminals are common). It is preferred to use only one from each
pair. If using both, combined output should not exceed 400mA.
(2) 9V outputs. Use for all ordinary pedals which operate from a 9V battery or
require less than 100mA.
(3) 9V high-current outputs. Use for all devices which require 400mA or less.
