1-Slot Thunderbolt 2 Expansion System for PCIe Cards

Connect a Full-Height, Half-Length+ PCIe Card to Computers Without Expansion Slots
With the Echo Express SE I, Sonnet has created a solution that leverages the paradigm shift enabled by Thunderbolt technology, allowing PCIe expansion slots to be connected outside a computer. This desktop Thunderbolt 2-to-PCIe card expansion system is ideal for connecting one professional video capture, audio interface, SAS or SATA HBA, 16Gb or 8Gb Fibre Channel, 10Gigabit Ethernet, or RAID controller PCIe card to any Mac® or Windows® PC with a Thunderbolt port.

20 Gbps Thunderbolt 2 Interface
The Echo Express SE I features 20Gbps Thunderbolt 2 which provides ample bandwidth for many of the most demanding, highest performance PCIe cards, and incorporates support for the DisplayPort 1.2 protocol which enables video streaming to a 4K video monitor. While the SE I delivers maximum performance when connected to a computer with Thunderbolt 2 ports, it is also fully compatible with computers with 10Gbps Thunderbolt, supporting most cards at full-performance.

Full Performance In a Small and Light Package
The Echo Express SE I is small, light, and perfect for use in situations where connecting only a single PCIe card is needed. Measuring a compact 5.6 inches wide by 8.6 inches long by 3.5 inches tall, the SE I was designed to have a small footprint, yet large enough to support the vast majority of Thunderbolt-compatible PCIe cards.

Smart Design Inside and Out
Constructed of rugged and lightweight aluminum, the outer shell of the Echo Express SE I securely protects the installed PCIe card. The card is protected inside, too. Instead of using a fixed speed fan that may not reliably cool a hot-running card, or a fan with a switch that leaves it up to you to guess the correct speed, the SE I employs a variable-speed, temperature-controlled fan to ensure the card and chassis’ components remain reliably cool.

One PCIe 2.0 Slot Plus Space for a Daughter Card
The Echo Express SE I’s PCIe 2.0 slot supports one half-length+, full-height, single- or double-width PCIe card. Double-width? Some specialty cards, such as RME’s HDSPe MADI FX card, Blackmagic Design’s DeckLink 4K Extreme, and the Lynx AES16e 50, 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.

Nearly Every Thunderbolt-Compatible PCIe Card Supported
Able to accommodate cards up to 7.75 inches long, Sonnet's Echo Express SE I supports nearly every Thunderbolt-compatible card available. PCIe 1.1, PCIe 2.0, and PCIe 3.0 cards are supported.

Quiet, Please
The Echo Express SE I was 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.

Strong Link in the Chain
This Sonnet solution supports daisy chaining of additional Thunderbolt technology-enabled peripherals such as an additional Echo Express chassis, the Apple® Thunderbolt Display, video capture devices, and data storage devices. For connected devices requiring extra power, 10 watts is provided through the daisy chain port to peripherals.

Thunderbolt Cable and ThunderLok^™ Included
Sonnet includes a Thunderbolt cable to connect the Echo Express SE I to your computer, and a ThunderLok Thunderbolt connector retainer clip to secure the cable to the Echo chassis.
