Construct a Broadcast Studio On Your Desktop
Run Two High-Bandwidth Cards at Full 6000 MB/s – SimultaneouslyAre 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.
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 SlotEcho 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 CardsPerformance Meets Possibility
Two PCIe 4.0 Slots and Power to SpareEcho II DV T5 Desktop features two x16 PCIe slots with support for a wide variety of cards. For power-hungry cards, Echo II DV T5 integrates a universal 400W power supply and includes dual 75W auxiliary power connectors (one for each card slot) for cards that require extra power, including AJA Kona 5, Blackmagic DeckLink 8K Pro G2 (with main board [SDI ports] only), and Avid Pro Tools | HDX. Designed without a power switch, Echo II DV T5 powers on and off automatically with the connected computer, saving energy in the long run. With no power switch, you can’t forget to turn off the system!
Flexible PCIe Card Support
Supports Thunderbolt Compatible, Single-width, Non-GPU CardsEcho II DV T5 Desktop supports Thunderbolt compatible, single-width, non-GPU PCIe 4.0, 3.1, 2.0, and 1.1 cards including video capture, streaming and transcoding; SSD storage; audio DSP; multi-port 10Gb and 25Gb Ethernet; SAS or SATA host bus adapter; and other specialty types.
