About Dunlop M238 Iso-Brick

Be empowered with the MXR M238 18V Iso-Brick Pedal Power Supply, a compact and powerful solution for your musical equipment needs. This high-quality power supply is designed to be pedalboard-friendly, offering a lightweight yet durable construction that won't weigh down or crowd your setup.

Engineered by the reputable brand Dunlop, this power supply features ten fully isolated outputs, ranging from 9V to 18V. This includes two variable 6V-15V outputs, designed with special noise-reduction circuitry for a quiet, interference-free operation.

The Iso-Brick Power Supply is not just small and light, but it also provides an abundance of quiet, noise-free DC power, ready to run a wide range of pedal types. Each of the ten outputs is fully isolated, effectively eliminating ground loop noise that could potentially end your gig prematurely.

Whether your equipment is analog or digital, positive or negative ground, this versatile power box has got you covered. The MXR team has meticulously designed these ten outputs to accommodate a variety of voltage and current requirements. This includes two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA, and two variable outputs adjustable from 6V to 15V at 250mA.

The two variable outputs can be used to emulate voltage "sag", a drained battery effect sought by many vintage tonechasers. The Iso-Brick Power Supply is housed in a small, lightweight casing that's built like a tank, ensuring its durability and longevity.

Featuring power on/off and connection status LEDs, this power supply ensures you're always in the know. Equip your pedalboard with the MXR M238 18V Iso-Brick Pedal Power Supply to ensure reliable and quiet operation, gig after gig.
