## Overview

The MXR Mini Iso-Brick is a compact, fully isolated power supply designed for guitar effects pedals. It features five outputs—four 9V outputs delivering 300mA each, plus one toggleable 9V/18V output with 800mA—providing versatile power for analog and digital pedals alike. Its included splitter cable allows daisy-chaining pedals on a single output, while LED indicators and a rugged stainless steel enclosure ensure reliable, noise-free performance for professional gigging musicians.

## Description

The Mini Iso-Brick Power Supply supplies quiet, noise-free DC power to wide range of pedal types while taking up less space than a candy bar. 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, this little box has what you need. First, let’s talk outputs. The 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 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. You can do this with all of the outputs simultaneously—just purchase the extra cables to do so. Finally, 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. Combine that with a lightweight housing that's built like a tank, and you can step on stage with confidence that your pedalboard will stay powered from gig to gig.

Review: Awesome Value and Great Ground Loop Noise Reduction! - I've looked at a lot of the popular power supplies on the market like some of the voodoo labs and Truetone 1spot bricks and this one seemed to have the right amount of outputs for the price. I'm surprised that these don't seem to be more popular. I had some noise before I bought this and now everything is quite and absolutely no noise (still a little pickup hum, but my noise gate squashes that completely; no power noise at all). The LEDs are very bright but I guess that is better than not bright enough. I have a Pedaltrain Pro and the cables were long enough that I was able to string my Time Machine nearly all the way to the opposite corner of the board. I was a little concerned about the "sag" outputs but it seems that you can just set them to 9V and they act as a normal 9V output. Also another huge point that I didn't really see anyone talking about on the internet: it seems to power the Digitech Whammy 5 flawlessly. NOTE: this is the version 5 that is 9VDC from the factory (not the AC older versions). So the original Whammy power brick and input say 1300mA, but the Whammy manual says that it consumes <265mA. I think the adapter is a generic Harmon adapter for many things and so they just want you to use what they already make which happens to be 1300mA max. The pedal will only pull the required amperage from the brick at 9V, which again is <265mA and I'm pretty confident that value is accurate, otherwise it wouldn't be in the manual. To be safe I put it on the 450mA output and it works great!

Review: Unexpected, but amazing results! - I have had a Boss PSM-5 daisy chain to power my pedals for decades. I've recently been making changes to my stomp boxes and gear, and wanted to finally splurge for an isolated power supply to help reduce ambient hum. I have 6 9v pedals needing power of various amperage requirements, and this power supply was recommended to me by experts on a YouTube channel I subscribe to. The unit itself is very sturdy and will hold up well to travel and gigs. Simple instructions included and I hooked all my pedals in and compared the before and after. Though it did some reduction of the ambient hum, it didn't eliminate it entirely. (I discovered that my guitar is the cause for the remaining him, something I still remedy with copper shielding tape.) I was a bit bummed, but I proceeded to discover an unexpected perk with this power supply. When I started playing, I noticed a much sharper clean tone as well as an increase in master volumes without touching my knobs. As I messed around using my various pedals, (wah, distortion, sustain, flange, compression/sustain) I was blown away with how they all sounded. Every effect sounds infinitely better with the M238. Signal volume is increased naturally and the attack and presence of each effect is crystal clear. I cannot wait to clean up my guitar wiring to get that studio-quality and interference free sound in the comforts of my house! Did yourself a favor and spend the money on a quality power supply like this one...

## Questions & Answers

**Q: Where can I purchase additional splitter cables?**
A: Sweetwater. Never looked at Amazon because I bundled with a bunch of other things I needed and Amazons instrument prices are a little ridiculous.  Some cables are twice the price you can get them for at Sweetwater.

**Q: Can you daisy chain it to the 18v output of the mxr full size brick?**
A: HI 
No you wouldn't be able to as the ISO Brick doesn't provide enough current to power another brick

**Q: Where can one find additional splitter cables for purchase after point of sale?**
A: Unfortunately these aren't available for individual purchase at the moment. We hope to add this to our line soon.

**Q: Will this power my 12V 500ma pedal safely?**
A: As far as I know, it'll either under power it (on the 9v setting) or blow it (on the 18v setting). Best look for one that specifically does 12v
