Part No. ECHO-EXP-SE1-T3

Compact. Full Performance.

Echo Express SE I

Compact, desktop 1-slot Thunderbolt to PCIe card expansion system (with support for daughter card)

Connect One Full-height, Half-length+ PCIe Card (Plus Daughter Card)

The processing power offered by Mac, Windows, and Linux computers with Thunderbolt™ ports is truly impressive for today's creative professionals. However, these sleek, thin devices come with a drawback: they lack PCIe expansion slots for adding cards that boost connectivity and processing capabilities. Sonnet offers the ideal solution with Echo™ Express SE I Thunderbolt Expansion System. This compact, one-slot system allows you to easily connect a single PCIe card to your computer.

The Thunderbolt Interface Connection

Professional Desktop PCIe Card Expansion – when connected to one of your computer’s Thunderbolt ports, Echo Express SE I allows you to connect a single professional PCIe card — such as a video capture device, audio interface, SAS or SATA host bus adapter, Fibre Channel, Ethernet, or RAID controller — along with a daughter card.

Nearly Every Thunderbolt-Compatible, Non-GPU PCIe Card Supported

Designed to accommodate cards up to 7.75 inches long, the compact Echo Express SE I supports nearly every Thunderbolt-compatible PCIe 4.0, 3.0, 2.0, and 1.1 card available. Not sure if your card is compatible? Check our compatibility list for cards that meet Thunderbolt requirements and are organized by fit and power compatibility with specific expansion systems.

All Around Smart Design: Aluminum Enclosure. Auto Power On/Off.

Echo Express SE I’s lightweight, yet rugged aluminum outer shell securely houses the installed PCIe card. 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.

One PCIe 3.0 Slot and Space for a Daughter Card

Echo Express SE I features an x8 PCIe slot, and supports one half-length+, full-height, single- or double-width PCIe card. Double-width? Some pro video and audio interface cards, such as Blackmagic Design’s DeckLink 4K Extreme, and RME’s HDSPe MADI FX card, include a daughter card that mates with and provides additional external connections to the main card. The daughter card occupies the adjacent space without filling a PCIe slot.

Quiet Please

Echo Express SE I is designed to be ultra-quiet so that it can be comfortably used in noise-sensitive environments. The airflow path within the chassis has been specially designed to enable the temperature-controlled, variable speed fan to quietly and efficiently cool the installed card at all times, even during peak operation.

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.

Connect Additional Thunderbolt Devices. One port is reserved for connecting to your computer; the second port enables connection of additional Thunderbolt peripheral devices in a daisy chain.

10 Gbps USB 3.2 Gen 2 Support. 10 Gbps USB 3.2 Gen 2 support allows you to connect a USB device to the second Thunderbolt port using the proper cable or adapter.

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 III Desktop 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. Watch this video to learn more about the performance benefits.
