Description

The ePSB-TA4F by AudioRoot is a compact, professional-grade USB-C adapter that enables you to power your audio equipment using modern USB-C Power Delivery (PD) or PPS-capable chargers. It converts the USB-C input into a regulated TA4F DC output, making it ideal for devices like power distributors, recorders, wireless systems, or mixers using the TA4 standard.

Engineered with smart power-switching logic, the ePSB-TA4F provides 15 V DC with standard USB-C PD chargers and 17 V DC when used with PPS-compatible power sources.
