Desktop 2-slot Dual Thunderbolt 5 Interface to PCIe Card Expansion System for Computers with Thunderbolt or USB4 Ports
Construct a Broadcast Studio On Your Desktop Run Two High-Bandwidth Cards at Full 6000 MB/s – Simultaneously Are you a creative pro using one of the hot new laptops or mini desktops with ultra-high-performance Thunderbolt™ 5 ports in your workflow? They offer tremendous onboard processing power, but don’t have the PCIe slots you need for connecting adapter cards to add specialized ports and processing capabilities critical to your workflow.
Sonnet Echo™ II DV T5 Desktop overcomes the no-slots limitation. This pro Thunderbolt 5 to PCIe card expansion system enables you to connect two full-length, single-width PCIe cards to your computer, each to a separate Thunderbolt port for maximum bandwidth to each card — it’s the ultimate solution for connecting cards with high bandwidth requirements.
Connect Echo II DV T5 to Two Thunderbolt 5 Ports on Your Computer for Maximum DV Performance
2x 6000 MB/s Engineered to Support Maximum Performance from Two Cards
Two PCIe 4.0 Card Slots. Dual Thunderbolt 5 Interfaces for Double the Bandwidth.
Some of the latest computers — including MacBook Pro (M4 Pro/M4 Max) , Mac mini (M4 Pro), Mac Studio (M3 Ultra/M4 Max), and select Windows PCs — offer multiple Thunderbolt 5 ports, each with its own independent bus delivering 6000 MB/s of PCIe bandwidth. Echo II DV T5 Desktop is designed to fully tap into that speed. Instead of sharing bandwidth across slots, it uses a dedicated Thunderbolt 5 interface for each slot, delivering full PCIe bandwidth to both cards at the same time. This means you can run two high-demand PCIe cards at full performance simultaneously — perfect for DV I/O, ultra-fast NVMe storage, and multi-port 10 and 25Gb Ethernet workflows.
2x the Bandwidth! Separate Thunderbolt 5 Interface for Each Card Slot
Echo II DV T5 provides full Thunderbolt PCIe bandwidth to each slot when connected to two computer Thunderbolt ports that also provide independent PCIe bandwidth — 6000 MB/s with Thunderbolt 5 computers, and 2880 MB/s with Thunderbolt 4, 3, and USB4 computers.
Dual Thunderbolt 5 Ports Connection Option for Maximum Performance Connect Two DV I/O or Other High-bandwidth Cards Directly to Two Thunderbolt 5 Ports On Your Computer for Full 6000 MB/s PCIe Bandwidth to Each Card
Single Thunderbolt Port Connection Option Also Works with Computers with Only One Available Thunderbolt Port to Support Two Cards
Only One Available Thunderbolt Port? Or, Does Your Computer Only Have USB4 Ports? Daisy Chain the Thunderbolt Interfaces to Connect Two PCIe Cards Via One Cable Because each PCIe card slot’s Thunderbolt 5 interface includes two Thunderbolt ports, you can connect the interfaces to each other to enable Echo II DV T5 Desktop to plug in to your computer with a single Thunderbolt cable.
