Use Two PCIe Cards With Any Mac with a Thunderbolt Port
Sonnet's Echo Express SE II enables you to connect two high-performance, professional pro video capture and processing, digital audio interface, DSP accelerator, FireWire, RAID controller, 10 Gigabit Ethernet, eSATA, and other PCIe cards to any Mac with a Thunderbolt port. Accommodating cards up to 7.75' long, this compact Thunderbolt 2*-to-PCIe card expansion chassis supports nearly every Thunderbolt-compatible PCIe card on the market, including double-width (PCIe card + daughter card) cards. Measuring just 6.5' wide by 4.6' tall by 11' long, the Echo Express SE II takes up little space wherever you work, be it in the studio, on location, at your desk, or in the edit suite. Like all Echo Express chassis, the SE II has two Thunderbolt ports that support daisy chaining of up to six devices to a single port on your computer.

Fast Today, Faster In the Future
Free Thunderbolt 2 UpgradeAs you may have heard, Thunderbolt 2 is coming! Apple announced the first Thunderbolt 2 technology-equipped computer, the new Mac Pro, but it won't ship until Fall 2013. The original 10Gbps Thunderbolt interface has provided breakthrough bandwidth for external expansion, more than sufficient to support the maximum performance of most PCIe cards. However, some high bandwidth cards such as 16Gb Fibre channel, multi-port 10 Gigabit Ethernet cards, or multiple bandwidth-hungry cards require more than 10Gbps. Thunderbolt 2 removes this barrier by providing more bandwidth for demanding applications.

Echo Express SE II chassis equipped with Thunderbolt 2 will be available when Thunderbolt 2 hosts, such as the new Mac Pro, ship in Fall 2013. Until then, Sonnet will ship the SE II equipped with 10Gbps Thunderbolt, and will include a coupon for one free exchange for an easy-to-install upgrade to 20Gbps Thunderbolt 2 (customer pays only shipping and handling costs). More information on the exchange program will be available when this product ships.

Thunderbolt LogoThunderbolt 2 Technology
The Echo Express SE II features the 20Gbps Thunderbolt 2 interface, ensuring that even the most demanding cards will perform at their peak with the new Mac Pro and other Thunderbolt 2 technology-equipped computers to follow. It is also backward compatible with 10Gbps Thunderbolt-equipped computers.

Cool Design Outside and In
The Echo Express SE II's aluminum outer shell securely protects the cards inside and helps transfer heat away from them. The large and quiet, temperature-controlled fan automatically speeds up and slows down smoothly as needed, so there's no guesswork in deciding which switch position to select. The enclosure is ventilated front, back, and bottom to facilitate airflow over the cards.

Two PCIe 2.0 Slots Plus Space for a Daughter Card
The Echo Express SE II's PCIe 2.0 x8 slots support two half-length+ (up to 7.75' long), full-height, single-width PCIe cards, or one single-width card plus one double-width 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 PCIe card space without filling a slot. The Echo Express SE II accommodates a daughter card's installation without wasting a slot.
