Sonnet - 'Echo II DV Desktop'

Sonnet Echo II DV Desktop

Connect Two Bandwidth-hungry Pro PCIe Cards to Computers with Thunderbolt PortsThe Sonnet Echo II DV Desktop is a professional Thunderbolt™ to PCIe card expansion system that enables you to connect two up-to-full-length (12.28 inches long), single-width PCIe cards to any Mac®, Windows®, and Linux® computers with high-performance Thunderbolt™ 4 or Thunderbolt™ 3 ports that lack the space and PCIe expansions slots to install specialty cards that are needed for video/audio inputs, transcode data, and connect high-speed shared storage and networks.

Designed to Support Maximum Performance

Two PCIE Card Slots, Dual Thunderbolt Interfaces for Double the BandwidthSome 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 the Bandwidth

image of two PCIe cards installed in Sonnect Echo II DV Module

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 silicon (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.

400W Power Supply

Two PCIe 3.1 Slots and Power to SpareEcho II DV Desktop features two x16 PCIe slots, enabling it to support a wide variety of cards. To support power-hungry cards, it 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.

Quiet Noctua Cooling

Dual Noctua FansFeaturing 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

40Gbps Thunderbolt Cables
and Thunderlok 3 Clips included
Sonnet includes two Thunderbolt cables that support Thunderbolt’s full 40Gbps bandwidth and are fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides two ThunderLok™ 3 Thunderbolt connector retainer clips that prevent accidental cable disconnections — just slide one 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.

40Gbps Thunderbolt
