MXR M239 Mini Iso-Brick 5-output Mini Isolated Pedal Power Supply

A SMALL BUT MIGHTY POWER SUPPLY

The MXR M239 Mini Iso-Brick Power Supply, which is smaller than a candy bar, provides silent, noise-free DC power to various pedal types. This tiny box provides everything you need, whether you need a storage solution for your compact travel board or you need to power a modest, carefully chosen assortment of tried-and-true essentials.

First, let’s talk about outputs. The MXR M239 Mini Iso-Brick Power Supply has five, and each is 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.

And don’t let the five outputs limit you—the MXR M239 Mini Iso-Brick Power Supply can accommodate the addition of an additional pedal if necessary. Given that both pedals need the same voltage and the output’s current limit is not exceeded, you can connect two pedals to a single output using the splitter cable that is included with the device. Simply acquire the additional cables to do this simultaneously with all of the outputs.

On dark stages, troubleshooting can be difficult, so the MXR M239 Mini Iso-Brick Power Supply has LEDs to let you know when all of your connections are secure. You can step on stage with the assurance that your pedalboard will remain powered from gig to gig when you pair that with a lightweight housing that is constructed like a tank.
