Description

The AudioRoot ePSB-XLR4 is a compact USB-C PPS power bridge adapter designed for powering professional audio and video equipment with maximum efficiency and reliability. By converting USB-C Power Delivery into a stable XLR4 DC output, this adapter offers a seamless way to integrate modern USB-C charging solutions with legacy or high-demand equipment. Whether you're powering a recorder, camera, or power distributor in the field or in a studio environment, the ePSB-XLR4 ensures dependable performance through smart voltage regulation and support for PPS (Programmable Power Supply) technology.

When connected to a standard USB-C PD power source, the ePSB-XLR4 delivers a steady 15 V DC output which is ideal for everyday use. For more advanced power configurations, pairing it with a PPS-compatible charger unlocks an elevated 17 V DC output. This is particularly valuable in dual power setups, where maintaining uninterrupted operation is critical. At 17 V, the ePSB intelligently prioritizes AC power over batteries, while enabling automatic, seamless switchover to battery backup if the USB-C connection is lost. Lightweight and portable at just 50 grams, the ePSB-XLR4 is a smart choice for professionals who demand flexibility, efficiency, and peace of mind in their power solutions.
