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.
