AudioRoot ePSB-HRS4

AudioRoot ePSB-HRS4

The ePSB-HRS4 is a compact USB-C PPS power bridge adapter that converts a USB-C power source into a stable HRS4 output. When connected to a standard USB-C PD charger, the ePSB delivers 15 V DC—ideal for powering recorders, mixers or power distributors. With a PPS-compatible USB-C charger, the output increases to 17 V DC. This ensures AC power takes priority over batteries: if mains power is lost or the USB-C cable is disconnected, the connected batteries seamlessly take over without interruption.
