MXRM238 ISO-Brick Power Supply Unit
Independent shopping perspective
The Korena take
MXR's M238 ISO-Brick organizes pedalboard power through 10 fully isolated DC outputs. The output set covers multiple voltage and current requirements, including four 9V current ratings, two 18V outlets, and two variable 6V–15V outputs. Those adjustable outputs can emulate voltage sag or a drained-battery effect. Power on/off and connection-status LEDs make the unit easier to check during setup, while its small, lightweight housing helps keep board space and added weight down.
Strong match
Who this is for
- Powering a pedalboard that needs several isolated DC outputs with different voltage and current requirements.
- Using variable 6V–15V outputs to create voltage sag or a drained-battery effect.
- Connecting analog or digital pedals with positive- or negative-ground requirements.
