About Dunlop M239 Mini Iso-Brick

You can trust the MXR M239 18V Mini Iso-Brick Pedal Power Supply to deliver reliable, noise-free DC power to your music or audio setup. This compact and powerful device is a perfect solution for those seeking a space-saving power supply for their travel board or a small, carefully selected range of essential pedals.

The Mini Iso-Brick Power Supply, brought to you by the reputable Dunlop brand, is not just durable but also versatile. It features five fully isolated outputs, each designed to eliminate any disruptive ground loop noise that could potentially end your gig prematurely. Four of these outputs deliver 9 volts of power at 300mA, while the fifth output is adaptable, providing either 9 volts or 18 volts at 800mA, depending on your specific needs.

This powerful pedal power supply is capable of accommodating almost any pedal, whether analog or digital, thanks to its generous current capacity and the ability to handle both negative and positive grounds. If you need to power an extra pedal, the Mini Iso-Brick Power Supply has you covered with a splitter cable that allows you to connect two pedals to a single output, provided they require the same voltage and do not exceed the output's current rating.

The Mini Iso-Brick Power Supply is designed with user convenience in mind. It features LEDs to ensure all your connections are solid, making troubleshooting on dark stages a breeze. Its lightweight yet robust housing is built to withstand the rigors of regular use, ensuring your pedalboard stays powered from one gig to the next. Trust in the MXR M239 18V Mini Iso-Brick Pedal Power Supply for a reliable, versatile, and compact power solution for your pedals.
