Audioroot eSMART TRIO Advanced Power Distributor

The Audioroot eSMART TRIO, an advanced power distributor, takes up to three power sources and feeds a sound bag or cart through eight DC outputs and two USB ports.

Three TA4M inputs take smart batteries or an external DC or AC supply, in setups such as dual batteries with load sharing, DC with battery backup, or three batteries in cascade. You can hot-swap any source without interrupting the system, and the unit switches between sources on its own, in priority order.

On the outputs, seven Hirose-compatible connectors handle up to 2.5 A each, and a TA4F output passes combined battery data to a mixer or recorder that reads smart batteries, such as those from Sound Devices. On the front, USB-C Power Delivery gives up to 45 W and USB-A Quick Charge 3.0 up to 15 W. Three OLED displays show system totals, run time, and each battery’s state, and fault protection cuts an overloaded output and retries every 40 seconds. Use two Li-96neo batteries for full performance, since total current runs to 11.5 A.
