Buying Guide

Output isolation

Choose isolated outputs to prevent ground loops and reduce noise when powering multiple pedals or keyboard modules

Total current capacity

Check the combined amperage to ensure the supply can handle peak draw from all your devices without voltage sag

Connector variety

Look for multiple DC outputs and at least one USB port if you need to power controllers, phones, or MIDI interfaces

Build quality and mounting

Metal chassis and rack/board mounting options improve durability and reduce vibration-related noise on stage

Regulation and ripple

Well-regulated outputs with low ripple deliver cleaner audio and protect sensitive keyboard circuitry
