The AudioRoot TRIAD-CCT-U is a passive power-combining cable engineered for professionals who need a compact, flexible, and smart-free solution for managing multiple DC power sources. Featuring three DC inputs and a dual USB-C + USB-A output, this configuration is ideal for setups that include both traditional Li-ion battery packs and modern USB-C AC power adapters. Its passive, non-telemetry design ensures compatibility with the Audioroot vmDBOX series and other non-SMBus power distributors, delivering uninterrupted power without the complexity of data merging or battery monitoring. With its built-in support for USB-C output, the TRIAD-CCT-U is particularly suited for modern power configurations, including USB-C-powered distribution hubs or accessories. When the third input uses USB-C, pairing it with a PPS-compatible USB-C PD adapter is strongly recommended to ensure accurate voltage regulation and to protect battery integrity. The 60 cm cable length provides optimal balance between flexibility and manageability in tight setups such as sound bags or field rigs. Whether you're extending runtime, hot-swapping batteries, or integrating AC backup, the TRIAD-CCT-U delivers clean, reliable power, wherever your gear takes you.
