Supports Every Thunderbolt 4 Compatible, Non-GPU PCIe Card

Echo III Rackmount supports every Thunderbolt compatible, non-GPU PCIe 1.1/2.0/3.0 card available including video capture and transcoding; audio DSP; 6Gb or 12Gb SAS or SATA host bus adapter; 10Gb or 25Gb Ethernet; SSD storage; and other specialty types to your system.

The best portable, mini desktop and all-in-one computers feature powerful CPUs and include high-performance Thunderbolt ports to support peripherals. But they lack the PCIe expansion slots creative pros need to install specialty adapter cards that enable their workflows by adding video and audio inputs, transcoding data, and connecting to high-speed shared storage and networks. Sonnet has a solution—the Echo III Rackmount—a professional Thunderbolt 3 to PCIe card expansion system that enables you to connect three (up to) full-length (12.28 inches long) PCIe cards to your computer at the same time, via a single cable.

No Thunderbolt 3? No problem—the Echo III Rackmount is also compatible with Macs with Thunderbolt 2 ports when used with the bi-directional Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt cable (both sold separately).

Mac Compatibility- Mac (Intel) with Thunderbolt 3 ports, Mac (M1) with PCIe cards that have M1 compatible drivers, Mac with a Thunderbolt 2 or Thunderbolt port with an Appl Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter plus a Thunderbolt 2 cable (both sold separately), macOS 10.12.6+, macOS Big Sur compatible

Windows Compatibility- PC with Thunderbolt 3 or Thunderbolt 4 ports, Windows 10 (Windows 11 does not support multiple-slot Thunderbolt expansion systems. We are working with Microsoft to resolve the issue.)

Linux Compatibility- Linux computer with Thunderbolt 3 ports, Linux Kernel 5.0+

Creatively Expandable

Plugged into one of your computer’s Thunderbolt 3 ports, the Echo III Rackmount system delivers 2750 MB/s of PCIe bandwidth and enables you to connect professional PCIe cards (three full-height, single-width cards, or one double-width card plus one single-width card).

Rack Ready! Rugged 2U Steel Rackmount Housing + Optional Expansion Space

The Echo III Rackmount’s included adjustable rackmount extension rails enable the 2U enclosure to be installed securely in a variety of racks from 16 to 24 inches deep.
