The MXR DC Brick (M237) is a power supply designed to provide reliable and noise-free power to multiple guitar effects pedals simultaneously. It is an updated version of the original DC Brick with improved circuit protection and efficiency.

Key Features:

• Outputs:
  
• • 8 × 9V DC outputs (each providing up to 120mA)
  • 2 × 18V DC outputs (each providing up to 250mA)
• 
  
• Short Circuit Protection: If a pedal draws too much current, the Brick isolates that output while keeping the others operational.
• LED Indicators: Each output has an LED that lights up when functioning properly and turns off if there’s a short or overload.
• Compact and Durable Design: Built with a rugged aluminum chassis, ideal for pedalboards.
• Universal Power Adapter: Comes with a 18V DC power adapter and cables for connecting pedals.

It’s a great choice for guitarists looking for a reliable and compact power supply without the bulk of isolated units
