MXRM237 DC Brick Power Supply
Independent shopping perspective
The Korena take
MXR’s M237 DC Brick organizes power for a ten-output pedal setup, with eight 9V connections and two 18V connections. It has twice the power handling of the earlier DCB10, plus short-circuit and overload protection. Each 9V output has its own red LED that lights when a short occurs, helping isolate a problem during setup or troubleshooting. The included AC adapter and pedal-connection cables provide the stated connections needed to get pedals linked to the unit.
Strong match
Who this is for
- Pedalboards needing power distributed across up to eight 9V and two 18V pedal connections.
- Troubleshooting a short on a 9V connection using the dedicated red output LED.
Consider the trade-offs
When to look elsewhere
- Rigs that need more than eight 9V outputs or more than two 18V outputs.
