Sonnet Echo II DV 2-Slot Thunderbolt to PCIe Card Desktop Expansion System

MAX DV Performance - Echo II DV Desktop
Desktop 2-slot, Dual Thunderbolt Interface to PCIe Card Expansion System for Computers with Thunderbolt Ports

Create a Desktop Broadcast Studio
Connect Two Bandwidth-hungry Pro PCIe Cards to Computers with Thunderbolt Ports

While these Mac, Windows, and Linux computers include high-performance Thunderbolt ports to support peripherals, they lack PCIe expansion slots necessary to install specialty cards that add needed video and audio inputs, transcode data, and connect to high-speed shared storage and networks.

Sonnet has the ultimate solution for cards with high bandwidth requirements - Echo II DV Desktop - a professional Thunderbolt Expansion System that enables you to connect two up to full-length (12.28 inches long), single-width PCIe cards to your computer, each to a separate Thunderbolt port (if needed) for maximum bandwidth to each card.

Dual Thunderbolt Interfaces - Double the Dedicated ted Bandwidth Bandwidth
• Connect DV I/O or Other Bandwidth-hungry PCIe Cards
• Dual Thunderbolt Interfaces for Maximum Bandwidth
• Full 2880 MB/s PCIe Bandwidth to Each Slot

Specially Designed to Support Maximum Performance from Two Cards
Two PCIe Card Slots. Dual Thunderbolt Interfaces for Double the Bandwidth.

Some computers - such as the latest MacBook Pro, Mac Studio, Mac mini and iMac - have multiple Thunderbolt ports that are supported by separate 40Gbps Thunderbolt buses and provide up to 2880 MB/s of PCIe bandwidth to each port. Among multi-slot Thunderbolt to PCIe card expansion systems, the Sonnet Echo II DV Desktop is unique. Instead of using one Thunderbolt interface for two or three slots - which dynamically allocates the PCIe bandwidth between them - Echo II DV employs one interface per slot. With each slot getting Thunderbolt's full PCIe bandwidth, you can exploit two cards' full potential when connected at the same time to separate Thunderbolt buses on the computer, ideal for cards with high bandwidth requirement such as DV I/O, NVMe SSD storage, and 10 and 25Gb Ethernet adapters.

It's All About That Bandwidth - Separate Thunderbolt Interface for Each Card Slot
By employing a separate Thunderbolt interface for each card slot, Echo II DV is designed to provide full PCIe bandwidth to each slot when connected to two computer Thunderbolt ports that also have independent PCIe bandwidth. Computers with independent PCIe bandwidth to two or more Thunderbolt ports include all Apple M series Macs, and Intel Macs or PCs with three or four Thunderbolt ports. (A few Pro PC laptops with only two Thunderbolt ports support independent PCIe Bandwidth. Check your computer's specifications.) Computers that share PCIe bandwidth between their Thunderbolt ports, that would provide only shared bandwidth to the two slots, include Intel Macs or PCs with only two Thunderbolt ports.

Dual Thunderbolt Ports Connection Option for Maximum Performance
Connect Two DV I/O or Other High-bandwidth Cards Directly to Two Thunderbolt Ports On Your Computer for Full PCIe Bandwidth to Each Card

Single Thunderbolt Port Connection Option
Also Works with Computers with Only One Available Thunderbolt Port to Support Two Cards

Versatile PCIe Card Support - Supports Every Thunderbolt Compatible, Single-width, Non-GPU Card
Echo II DV Desktop supports every Thunderbolt compatible, single-width, non-GPU PCIe 4.0, 3.1, 2.0, and 1.1 card available including video capture, streaming and transcoding; SSD storage; audio DSP; 10Gb or 25Gb Ethernet; SAS or SATA host bus adapter; and other specialty types to your system.

Two PCIe 3.1 Slots and Power to Spare
Echo II DV Desktop features two x16 PCIe slots with support for a wide variety of cards. For power-hungry cards, Echo II DV integrates a universal 400W power supply and includes dual 75W auxiliary power connectors (one for each card slot) for non-GPU cards that require extra power, including AJA Kona 5, Blackmagic DeckLink 8K Pro, Bluefish444 Epoch and KRONOS SDI cards, and Avid Pro Tools | HDX. Designed without a power switch, Echo II DV 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!

Ultra-quiet Operation - Dual Noctua Fans
Featuring dual Noctua fans, Echo II DV is designed to deliver ultra-quiet operation so that it can be comfortably used in noise-sensitive environments. Rated at 17.1dBA - below the 20dBA ceiling prescribed for use in recording and broadcast studios - the fans spread the spectrum of their noise to minimize the impact at any single frequency. To further ensure negligible noise levels, the fans are temperature-controlled, automatically speeding up and slowing down smoothly as needed, and the enclosure is engineered to optimize airflow over the installed cards to effectively and efficiently cool the system.

Secure Connections for High Performance - Thunderbolt Cable and ThunderLok Included
Sonnet includes a Thunderbolt cable that supports Thunderbolt's maximum bandwidth and is fully compatible with Thunderbolt 5, 4, and 3 computers. Sonnet also provides ThunderLok, a Thunderbolt connector cable lock, that prevents accidental cable disconnections.

ThunderLok Advantage
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.

Thunderbolt Technology - Fastest External Interface Available
Sonnet Thunderbolt products feature a high-speed Thunderbolt interface that delivers PCIe bandwidth needed to support data transfers at full speed.

Four 40Gbps Thunderbolt Ports
Two ports are reserved for the connections to your Thunderbolt computer (one for each PCIe slot); the other two ports enable expansion of up to five additional Thunderbolt peripheral devices each in daisy chains.

10Gbps USB 3.2 Gen 2 Support
10Gbps USB 3.2 Gen 2 support allows you to connect a USB device to secondary Thunderbolt ports using the proper cables or adapters.

Provides 15W of Power
For peripherals requiring extra power, 15 watts is provided to bus-powered devices through the secondary Thunderbolt port.

Supports Connecting Up to One 8K Display
Maximize the utilization of one computer Thunderbolt port, connecting the largest display supported by your computer.

Designed for the Fastest Connection to Thunderbolt Computers
Echo II DV is purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum simultaneous ingest speeds.

Compatible with DuoModo Enclosures
Echo II DV Module is compatible with our DuoModo family of modular Thunderbolt expansion systems, comprised of interchangeable modules and enclosures so you can quickly and easily interchange modules depending on your workflow.

Adds Connectivity & Capabilities
Connects two high-performance non-GPU PCIe cards via one or two Thunderbolt cables to your computer lacking expansion slots.

Dual Thunderbolt Interfaces
One interface per slot supports full PCIe bandwidth to each installed card, enabling maximum performance at the same time.

Four Thunderbolt Ports
Two ports connect to computer for maximum performance; secondary ports support daisy-chaining of Thunderbolt interfaces to enable single-cable connection to computer.

Broad PCIe Card Compatibility
Every Thunderbolt compatible, single-width, non-GPU card supported regardless of length or height.

Connect to Two Computers
You can connect each side of the Echo II DV to a separate computer. Each side operates independently of the other. It's like having two single-slot systems in one, saving rack or desktop space.

Remarkably Quiet
Dual temperature-controlled, variable-speed Noctua fans rated at 17dBA automatically and quietly cool the cards.
