Sonnet Echo III Desktop

Connect three full-length PCIe cards to computers with Thunderbolt 3 ports. For creative professionals who use the latest portable, mini-desktop, and all-in-one computers in their workflows, onboard processing power alone isn't enough to get the job done. While these computers have high-performance Thunderbolt 3 ports to support peripherals, what they lack are PCIe expansion slots for installing specialty cards that add needed video and audio inputs, transcode data, and connect to high-speed shared storage and networks. Sonnet has a solution, the Echo III Desktop – a professional Thunderbolt 3 to PCIe card expansion system that allows you to connect three (up to) full-length PCIe cards (12.28 inches long) simultaneously using a single cable.

features
• Adds connectivity and capabilities: Connects up to three high-performance non-GPU PCIe cards to your computer without expansion slots via a Thunderbolt 3 cable.
• Pro Tools | HDX Compatible: HDX Compatibility Mode allows you to use up to three Pro Tools | HDX PCIe cards without the need for additional parts.
• Wide PCIe card compatibility: Any Thunderbolt 3 compatible, non-GPU compatible card is supported regardless of length or height.
•Three PCIe 3.0 slots: One x16 plus two x8 slots support three full-height, single-width cards or one double-width card plus one single-width card.
•Pro Power Integrated: 400W power adapter with 75W auxiliary power. Saves energy by automatically turning on and off with the computer.
