AUDIOROOT eSMART TRIO advanced power distributor

The AUDIOROOT eSMART TRIO is a professional-grade, portable power distribution system specifically engineered for location sound recordists. Designed with adaptability, reliability, and data intelligence in mind, it supports up to three independent power sources—including smart batteries and external DC/AC power supplies—and efficiently distributes power via 8 DC outputs and 2 USB ports.

Whether you're running a mobile sound bag or a cart-based setup, the eSMART TRIO ensures seamless power delivery, intelligent battery monitoring, and hot-swappable redundancy, offering unmatched flexibility for critical field operations.

🔋 Smart & Seamless Power Management

• 3 Power Inputs (TA4M connectors) allow for a variety of configurations:

  • Single smart battery

  • Dual batteries with load sharing

  • External DC input with battery backup

  • High-priority battery with backup

  • Triple-battery cascading configuration

• Hot-swapping supported: Remove or connect power sources without interrupting system operation

• Intelligent power source prioritization with auto-switching and high-priority routing

• smBUS Data Passthrough: Real-time battery data aggregation and monitoring

• Overcurrent and Short Circuit Protection: Active fault detection system cuts output and retries automatically every 40 seconds until the fault clears

⚡ Output Connectivity & Control

• 7 x Hirose™-compatible DC outputs:

  • 6 on rear (4 main, 2 switchable auxiliary)

  • 1 front panel auxiliary (AUX2)

• 1 x TA4F Switchcraft™-compatible output:
