ESP Project 96 – 48V Phantom Power Supply

Projects > ESP Project 96 - 48V Phantom Power Supply

Whether you are building a preamp (or several), or needing to work with a console/preamp that has no built-in phantom power- ESP founder Rod Elliott’s design for a regulated phantom power supply maintains a low component count, is easily expandable to multiple channels, and keeps a small footprint. In addition, it outperforms many affordable, commercially-available phantom power supplies that rely on using less than 48V, or do not supply enough current.
