For both battery operated and high current DSP effects, the Pedal Power X4-18V is a professional isolated power supply. Its ultra-compact size fits even the smallest pedalboards-including Voodoo Lab Dingbat TINY and Pedaltrain Nano-and operates at any mains voltage for international touring. X4's innovative hybrid DC transformer design incorporates exotic components, linear regulation, and computer optimized filtering to establish industry-leading audiophile quality power that unveils the hidden sonic potential of your rig. As well as delivering the cleanest, most reliable power for small pedalboards, Pedal Power X4-18V also shines as a supplementary power supply for an expanding rig. Powering directly from a Pedal Power 3 X-Link expansion port or any 12V 400mA DC output, X4-18V adds four isolated outputs to an existing Voodoo Lab power supply. X4-18V can also power from the AC courtesy outlet of a Pedal Power 2 PLUS to upgrade its isolated output capacity and high current capability.
