The long history

The MXR Iso-Brick Pro power supply delivers clean, stable voltages to a wide range of pedal types in a sleek form factor, allowing you to power your entire board confidently without any extra volume.

Powerful versatility

Each output on the MXR Iso-Brick Pro is fully isolated to preserve signal purity and eliminate ambient noise.

Even high-demand multi-effects units are covered, with a dedicated 9V DC output at 1.5 A for devices like the Line 6 HX Effects processor and HX Stomp amp/modeler.

Looking to expand your setup?

The MXR Iso-Brick Pro features a dedicated 18V DC link output at 2.0A, allowing seamless connection to a secondary power supply such as the MXR Iso-Brick Power Supply or the MXR Iso-Brick Mini Power Supply.

All in one

With its compact and lightweight design, the MXR Iso-Brick Pro power supply is perfectly sized to fit under most Pedaltrain pedalboards—and it comes with all mounting brackets and screws needed for installation.
