MXR brings you an efficient solution to all your pedal powering needs. Featuring noiseless DC power, this pedal is capable of supplying multiple types of pedals to help you meet your performance needs with one very compact package.

Noiseless DC Power
The name of the game with power supplies these days is noiseless. MXR has that down. This brick is noise free, meaning there's no interference between pedal power outputs, keeping your rig sounding clean. No fuzz, no buzz, no worries.  

Capable of Supplying Multiple Types of Pedals
The Mini Iso-Brick has five distinct outputs, capable of handling either negative or positive grounds. Four of the outputs, located on the long side of this rectangular brick, supply 9 volts at 300mA. A fifth can be switched between either 9 volts or 18 volts, at 800mA. There's even a splitter cable included which converts one output to handle two pedals, as long as they use the same voltage and do not exceed the output's rating. With plenty of power to go around, the MXR Mini Iso-Brick can handle almost any pedalboard setup.

Very Compact Package
The MXR Mini Iso-Brick gives you a lot for a little. Despite all its powering ability, it's about the size of a candy bar. You'll have no trouble fitting this brick on any pedalboard, no matter how light you're traveling. It even has LEDs to let you know your connections are intact.
