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.
Phantom Power Supply Features:
- Regulated phantom power achieved via discrete voltage doubler/rectifier
- Supplies 48VDC at 100mA (with a potential for up to 200mA, enough to supply phantom power to 20 channels)
- Each board measures 2.5″ x 1.5″
Price:
- $15 for supply PCB, $15 for preamp/microphone interface board
More Information:
- Entire project documentation found on Elliot Sound Products
- PCBs available at the ESP web store
