Sonnet Echo II DV T5 Desktop enclosure 2x PCIe 4.0 to 2x Thunderbolt 5 80Gb/s port

Maximum DV performance with Thunderbolt 5 Echo II DV T5 Desktop

Sonnet Echo II T5 Desktop is a 2-slot Dual-Thunderbolt 5 interface for PCIe 4.0 cards for computers with Thunderbolt or USB4 ports

Create a TV studio on your desktop computer – use two high-bandwidth cards simultaneously at full speed up to 6,000 MB/s

Do you use one of the latest laptops or mini desktop computers with ultra-high-performance Thunderbolt™ 5 ports for your creative work? Without PCIe expansion slots, the computing power of these computers alone is unlikely to be enough to handle all your tasks. You still need specialized cards that add essential video and audio I/O, transcode data, and connect to high-speed networks or shared storage. The Sonnet Echo II DV T5 Desktop eliminates this limitation. This professional Thunderbolt 5 to PCIe card expansion system connects two full-length, single-width PCIe cards to your computer. Each connects to a separate Thunderbolt port, providing maximum bandwidth for each—the best solution for connecting cards with high bandwidth requirements.

Designed for Maximum Performance: Two PCIe 4.0 Slots with 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 exploit 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.

Two Times 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 and 3 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.

Performance Meets Possibility – Two PCIe 4.0 Slots and Power to Spare

Echo 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 Cards

Echo 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.

Not sure if a card you own or are considering is compatible? We’ve put together a compatibility list that identifies many cards conforming to Thunderbolt technology requirements and organized by fit and power compatibility with specific expansion systems.

Dual Noctua Fans – Ultra-quiet Operation Rated at 17dBA

Echo II DV T5 Desktop can be comfortably used in noise-sensitive environments. Delivering ultra-quiet operation, its dual Noctua fans operate at below the recommended 20dBA limit for recording and broadcast studios and spread their noise across a range of frequencies, reducing the impact at any one frequency. To further guarantee trivial noise levels, the fans are temperature-controlled, automatically speeding up and slowing down smoothly as necessary, and the enclosure supports optimized airflow over the installed cards to effectively and efficiently cool the system.

Light. Rugged. Smart.

Echo II DV T5 Desktop system’s lightweight, rugged aluminum outer shell securely houses the installed PCIe cards. Because it automatically powers on and off with your computer, there is no power switch on the enclosure, ensuring you don’t waste energy by forgetting to turn it off.

Secure Connections for High Performance – Thunderbolt 5 Cables and ThunderLoks Included

Sonnet includes two Thunderbolt cables engineered to deliver Thunderbolt 5’s full bandwidth and power delivery performance. The cables are fully compatible with Thunderbolt 5, 4, and 3, and USB4 computers. Three Sonnet ThunderLok Thunderbolt connector locks are also included to prevent accidental cable disconnections.
