Sonnet Echo Express SE IIIe Thunderbolt Three-Slot PCIe Card Expansion System

3-slot Desktop Thunderbolt to PCIe Card Expansion System for Computers with Thunderbolt 4 or Thunderbolt 3 Ports Connect Three Full-height, Half-length+ PCIe Cards Although Mac®, Windows®, and Linux® computers with Thunderbolt™ 4 or Thunderbolt 3 ports offer processing power to spare, for many users (such as pros in the creative fields) onboard processing power alone is not enough. The computers lack the PCIe expansion slots needed to install specialty cards that add video and audio inputs, transcode data, and connect to high-speed shared storage and networks. Sonnet’s Echo™ Express SE IIIe is a compact, desktop Thunderbolt to PCIe card expansion system that enables you to connect three professional PCIe cards to your computer at the same time, via a single Thunderbolt cable. Nearly Every Thunderbolt-Compatible, Non-GPU PCIe Card Supported Smaller than the 3-slot Echo III Desktop, the Echo Express SE IIIe is still large enough to support nearly every Thunderbolt compatible, non-GPU card available. With its three x8 slots, the SE IIIe supports PCIe 4.0, 3.0, PCIe 2.0, and PCIe 1.1 cards up to 7.75 inches long. Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a list in our supporting PCIe Card Thunderbolt Compatibility Chart (PDF). There you’ll find cards identified as conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion system. Design Smarts Aluminum Enclosure. Auto Power On/Off. The inside of the Echo Express SE IIIe is wrapped in a rugged, yet lightweight aluminum outer shell, resulting in a lightweight system small enough to carry in your backpack, yet durable enough to protect the installed PCIe cards securely. Since Echo Express products automatically power on and off with your computer, there is no power switch on the chassis, ensuring you don’t waste energy by forgetting to turn it off. Three PCIe 3.0 Slots for Demanding Professional Needs ‍Echo Express SE IIIe’s PCIe 3.0 x8 slots support three half-length+, full-height, single-width PCIe cards, or one single-width card plus one double-width card. Double-width? ‍Some specialty cards, such as RME’s HDSPe MADI FX, Blackmagic Design’s DeckLink 4K Extreme, and the Lynx AES16e 50, include a daughter card that mates with and provides additional external connections to the main card. Power to Spare ‍Echo Express SE IIIe includes an auxiliary PCIe power connector, enabling you to install a card requiring extra power, such as the AJA® Kona® 5 or Blackmagic DeckLink 4K Extreme 12G, and Bluefish444’s Epoch and KRONOS SDI cards. All the Right Connections 40Gbps Thunderbolt Cable and ThunderLok 3 Included Sonnet includes a Thunderbolt cable that supports Thunderbolt's full 40Gbps bandwidth, and is fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides a ThunderLok™ 3 Thunderbolt connector retainer clip(1) that prevents accidental cable disconnections—just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.
