Echo Express III-D (Thunderbolt 3 HDX Edition)

- Description
Connect Three Full-Length PCIe Cards to Computers with Thunderbolt 3 Ports
NEW MODEL OPTIMIZED FOR THREE AVID PRO TOOLS | HDX CARDS
For pros working in the creative fields, a computer’s processing power alone is not enough to get the job done. A prime example is the latest MacBook Pro®, which, while offering great performance, lacks the PCIe expansion slots necessary to support specialty cards that connect pro video and audio inputs, transcode data, and connect to high-speed storage and networks. Instead of slots, these computers include high-performance Thunderbolt™ 3 ports to support peripherals. Sonnet’s Echo™ Express III-D (Thunderbolt 3 Edition) is a pro-level, desktop Thunderbolt™ 3 to PCIe card expansion system that enables you to connect three full-length PCIe cards at the same time.
Echo Express III-D (Thunderbolt 3 HDX Edition): Desktop Expansion
Optimized for use with multiple Pro Tools | HDX PCIe cards, Echo Express III-D (Thunderbolt 3 HDX Edition) provides three PCIe card expansion slots in a desktop enclosure. It supports three single-width, full-length PCIe cards, or one double-width, full-length card plus one single-width card, enabling it to support every Thunderbolt 3 compatible, non-GPU PCIe 1.1, PCIe 2.0, and PCIe 3.0 card available.
