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.
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.
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.
with M4 Pro, M4 Max, and M3 Ultra Macs and a few pro Thunderbolt 5 PCs
with Intel Macs, and PCs with Thunderbolt 4 (40 Gbps) Ports
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.
with Intel Macs or PCs with only Two Thunderbolt Ports
Connects two high-performance non-GPU PCIe cards via one or two Thunderbolt cables to your computer without expansion slots.
Supports full Thunderbolt 5 PCIe bandwidth (6000 MB/s) to each installed card.
One interface per PCIe 4.0 slot enables maximum performance from two cards at the same time.
Two ports connect to the computer for maximum performance; secondary ports support daisy-chaining of Thunderbolt interfaces to enable single-cable connection to the computer.
Every Thunderbolt compatible, single-width, non-GPU card supported regardless of length or height.
Each Echo II DV T5 PCIe slot operates independently of the other, enabling you to connect them to separate computers.
Two 75W auxiliary PCIe power connectors for power-hungry cards; secondary Thunderbolt ports provide 15W of power each to connected peripherals.
Dual temperature-controlled, variable-speed Noctua fans rated at 17dBA automatically and quietly cool the cards.
Provides robust and secure protection.
Supports all M series Macs, and Intel Macs with Thunderbolt 3 ports.
Supports Windows computers with Thunderbolt 5 or 4, or USB4 ports.
Supports Linux computers with Thunderbolt 5 or 4, or USB4 ports.
Founded in 1986 in Orange County, Southern California — long recognized as a vibrant hub of technology and engineering — Sonnet has been at the forefront of innovation for nearly four decades. We’ve introduced award-winning products that expand performance and connectivity for Mac, Windows, and other industry-standard computers. Many of our team members have been with us for more than 20 years, bringing unmatched expertise across both current and legacy products. Should you ever need technical support, you can count on our knowledgeable staff to provide the help you need.
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!
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.
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.
Many Sonnet Thunderbolt products featuring Thunderbolt ports come equipped with threaded mounting holes to securely attach a Sonnet ThunderLok connector lock, preventing Thunderbolt cables from accidentally disconnecting.
Echo II DV T5 Rackmount
Choose between Echo II DV Desktop and Echo II DV T5 Rackmount to suit your workflow needs. Echo II DV Rackmount mounts in a rack space 2U tall, and is only 16.5 inches deep, making it ideal for use in a wide range of popular mobile racks, carts, and rack cases, and in server rooms as well. Echo II DV T5 Rackmount even offers space for an optional expansion module.
Echo II DV T5 Module is the foundation of Sonnet’s powerful, maximum bandwidth Thunderbolt expansion systems. It is available as part of xMac mini (2024+) and xMac Studio rackmount Thunderbolt enclosure systems, enabling flexible, high-performance integration with Mac mini and Mac Studio computers.
xMac mini (2024+)/Echo II DV T5
Choose xMac mini (2024+)/Echo II DV T5 configuration to install and connect one or two M4 Pro Mac minis to an Echo II DV T5 Module.
xMac Studio/Echo II DV T5
For ultimate expansion, pair an Echo II DV T5 Rackmount with an xMac Studio/Echo II DV T5 to connect up to four bandwidth-hungry PCIe cards to a Mac Studio (M3 Ultra or M4 Max) — each through a dedicated Thunderbolt port for maximum performance.
