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 yourcomputer'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 cardsin one enclosure.
