Description

The AudioRoot ePSB-HRS4 is a professional-grade USB-C adapter that transforms modern USB-C Power Delivery (PD) sources into a stable HRS4 DC output which is ideal for powering audio recorders, power distributors, or other DC-powered equipment used in location sound and ENG setups.

This ultra-compact adapter supports both standard 15V PD output and advanced 17V PPS output. When used with a PPS-compatible USB-C charger, the ePSB-HRS4 delivers a higher 17V DC, enabling hybrid AC/battery power systems where the AC source is prioritized. If USB-C power is interrupted or disconnected, the unit seamlessly switches to battery backup, ensuring zero downtime.
