Connect Two Demanding DV I/O Cards to Computers with Thunderbolt 4 or Thunderbolt 3 Ports
For creative pros in the audio and video broadcasting industries, using the latest high-performance notebook, compact desktop, and all-in-one computers require multiple I/O ports. While these Mac®, Windows®, and Linux® computers include high-performance Thunderbolt™ 4 or Thunderbolt 3 ports, they lack PCIe expansion slots to install specialty cards with dedicated bandwidth to each card.

Make Your Broadcast Studio – Echo II DV Desktop
Computers such as Mac Studio and other M series Mac computers feature powerful Thunderbolt/USB4 ports, each individually driven by their own dedicated Thunderbolt bus. To harness this dedicated power, Sonnet has a creative solution — the Echo™ II DV Desktop — a professional Thunderbolt to PCIe card expansion system that enables you to connect two (up to) full-length (12.28 inches long) PCIe cards at the same time, via two cables. The Echo II DV Module exploits your computer’s full potential, connecting two PCIe 3.0 card slots — each with its own Thunderbolt interface — for you to install two bandwidth-hungry DV I/O cards in one enclosure.

Note: For maximum performance with more than one bandwidth-hungry PCIe card, such as the DeckLink 8K, this product requires connection to two Thunderbolt ports on computer.

When your computer has only one Thunderbolt port, you can still use Echo II DV Desktop. Because each PCIe card slot is supported by its own Thunderbolt interface with two Thunderbolt ports, you can take advantage of Thunderbolt’s daisy-chaining feature. Simply connect one Thunderbolt interface to the other using one of the two supplied Thunderbolt cables, and use the other cable to connect to the computer.
