Echo Express III-D (Thunderbolt 3 HDX Edition)

Echo Express III-D (Thunderbolt 3 HDX Edition)

3-slot Desktop Thunderbolt 3 Expansion System for PCIe Cards, Optimized for Use with Multiple Pro Tools | HDX PCIe Cards

Connect Three Full-length PCIe Cards to Computers with Thunderbolt 3 Ports

For pros working in the creative fields, a computer’s processing power alone is not enough to get the job done. Prime examples are the latest MacBook Pro®, and Mac mini®, which, while offering great performance, lacks the PCIe expansion slots necessary to support specialty cards that connect pro video and audio inputs, transcode data, and connect to high-speed storage and networks. Instead of slots, these computers include high-performance Thunderbolt™ 3 ports to support peripherals. Sonnet’s Echo™ Express III-D (Thunderbolt 3 HDX Edition) is a pro-level, desktop Thunderbolt™ 3 to PCIe card expansion system that enables you to connect your computer to three full-length PCIe cards at the same time.

PCIe Cards

Every Thunderbolt 3 Compatible, Non-GPU Card Supported

Echo Express III-D supports three single-width, full-length PCIe cards, or one double-width, full-length card plus one single-width card, enabling it to support every Thunderbolt 3 compatible, non-GPU PCIe 1.1, PCIe 2.0, and PCIe 3.0 card available. Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a list in our supporting PCIe Card Thunderbolt Compatibility Chart (PDF). There you’ll find cards identified as conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion system.

All Around Smart Design

Aluminum Enclosure. Auto Power On/Off.

Echo Express III-D is wrapped in a rugged, yet lightweight aluminum outer shell, resulting in a system light enough to carry without weighing you down, yet sturdy enough to securely protect the installed PCIe cards. Since Echo Express products automatically power on and off with your computer, there is no power switch on the chassis, ensuring you don’t waste energy by forgetting to turn it off.

Three PCIe 2.0 Slots

Sonnet’s Echo Express III-D supports three full-size PCIe cards, up to 12.28 inches (full-length) long. The III-D integrates a universal 300W power supply and includes a 75W PCIe power connector for cards that require supplementary power, such as the Avid Pro Tools|HDX. Even with all that power, the III-D is enviro-friendly; it automatically powers on or off whenever the connected computer powers on (or wakes), or powers off or sleeps, respectively.

Fan Icon

Quiet Operator

Echo Express III-D is designed to be ultra-quiet so that it can be comfortably used in noise-sensitive environments. Its two large, slow-spinning fans, enhanced with computer-modeled airflow management, ensure that even hot-running cards remain reliably cool without the need to install an extra PCIe blower card that would prevent the use of one of the three slots. Because the fans automatically speed up and slow down as needed, you don’t have to guess which speed setting to select, and there’s no need for tools to change settings.
Thunderbolt 3 Cable with ThunderLok 3

Included at No Extra Charge

Thunderbolt 3 Cable. ThunderLok 3.

Sonnet includes a 0.7-meter Thunderbolt 3 (40Gbps) cable that, unlike some other cables, transfers data at Thunderbolt 3’s full 2750 MB/s bandwidth, and supports up to 100W of Power Delivery (PD). Sonnet also provides a ThunderLok 3 Thunderbolt connector retainer clip(1) that prevents accidental cable disconnections—just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.

Thunderbolt 3 Port Info Icon

Thunderbolt 3 –
The USB C That Does It All

Echo Express III-D (Thunderbolt 3 HDX Edition) includes two Thunderbolt 3 ports; the first connects it to your computer, while the second supports daisy chaining of up to five additional Thunderbolt peripheral devices to a single port on your computer. The III-D also includes 10Gbps USB 3.2 Gen 2 support, meaning you can connect a USB device to the second port using the proper cable or adapter. For connected peripherals requiring extra power, 15 watts is provided to connected bus-powered devices. With the ability to handle multiple demanding, high performance PCIe cards, support for connecting two 4K displays @ 60Hz or one 5K display @ 60Hz(2), and support for a vast array of Thunderbolt(3) and USB(4) devices, Thunderbolt 3 is a leap forward in every way.
