MXR M239 Mini Iso-Brick Power Supply – Compact, Quiet, and Reliable Pedalboard Power
Big Power. Tiny Package.
Whether you need a space-saving solution for your downsized travel board or you just need to power a small, carefully curated selection of tried-and-true staples, the MXR Mini Iso-Brick Power Supply has what you need—all while taking up less space than a candy bar. This compact power supply delivers quiet, noise-free DC power to a wide range of pedal types, making it the perfect solution for musicians who demand reliable performance without sacrificing pedalboard real estate.
Five Fully Isolated Outputs
The Mini Iso-Brick Power Supply features five outputs, each fully isolated to eliminate obnoxious, gig-ending ground loop noise. Four of the outputs supply 9 volts of power at 300mA, while a fifth can be set to provide either 9 volts or 18 volts at 800mA depending on your needs. With a generous amount of current on tap and the ability to handle both negative and positive grounds, these outputs will accommodate almost any pedal, analog or digital.
Flexible Power for Any Pedal
Don't let the five outputs restrict you—if you need to add an extra pedal, the Mini Iso-Brick Power Supply has you covered. It comes with a splitter cable that can be used to connect two pedals to a single output, provided they require the same voltage and you don't exceed the output's current rating. This flexibility ensures your pedalboard can grow with your needs without requiring a larger power supply.
LED Indicators for Easy Troubleshooting
Troubleshooting can be a hassle on dark stages, so the Mini Iso-Brick Power Supply comes equipped with LEDs to let you know that all your connections are solid. No more guessing whether a pedal is receiving power—simply glance at the LEDs and know your board is ready to go.
Built Like a Tank
The Mini Iso-Brick Power Supply features a lightweight housing that's built like a tank, ensuring it can withstand the rigors of touring and regular use. Step on stage with confidence that your pedalboard will stay powered from gig to gig.
