Connect Three Full-Length PCIe Cards, via a Single Cable
For creative professionals using the latest portable, mini desktop, and all-in-one computers, onboard processing power alone often is not enough. While these Mac, Windows, and Linux computers include high-performance Thunderbolt 5 ports to support peripherals, what they lack is PCIe expansion slots for specialty cards that add video and audio inputs, transcode data, or connect to high-speed shared storage and networks. The Echo III Desktop is a professional Thunderbolt to PCIe card expansion system that connects up to three full-length (12.28 inches long) PCIe cards at the same time, via a single Thunderbolt cable.

Three PCIe 3.0 Slots and Power to Spare
The Echo III Desktop features one x16 and two x8 PCIe 3.0 slots, enabling it to support a wide variety of cards at the same time. To support power-hungry cards, it integrates a universal 400W power supply and includes a 75W auxiliary power connector for non-GPU cards that require extra power, including the Avid Pro Tools | HDX.

Dual Fans. Ultra-Quiet Operation.
Featuring dual Noctua fans, the Echo III Desktop is designed to deliver ultra-quiet operation for use in noise-sensitive environments. The fans are temperature-controlled, automatically speeding up and slowing down as needed, and the enclosure is engineered to optimise airflow over the installed cards for effective, efficient cooling.

Avid Pro Tools Qualified
At the flick of a switch, the Echo III Desktop is instantly optimised to support up to three Pro Tools | HDX PCIe cards, with no extra parts necessary.
