An 18V DC link output at 2A lets you connect two power supplies together for additional capacity. With the M242, you can build your ideal pedalboard with confidence that clean, steady power is available for every stompbox.

Dedicated High-Current Output for Digital Multi-Effects

In addition to its eight main outputs, the M242 provides a dedicated 9V DC output at 1.5A. This high-current feed is perfect for power-hungry digital multi-effects units.

Your delay tails will remain pristine and preset switching will be fast.
