Create a desktop broadcast studio with the Echo II DV Desktop from Sonnet. Designed for Windows, Mac, and Linux systems that lack available PCIe slots, its dual PCIe 3.0 x16 slots let you simultaneously connect two full-height, full-length PCIe cards using two cables. Each slot has its own Thunderbolt interface and supports bandwidth-hungry, non-GPU I/O cards, such as the AJA Kona 5 and Blackmagic DeckLink 4K Extreme 12G. Connectivity to your host system is achieved using dual 40 Gb/s Thunderbolt 3 ports, with data transfers that reach as high as 3000 MB/s with Thunderbolt 4 and 2570 MB/s with Thunderbolt 3. Power is provided by an integrated 400W PSU with dual 75W auxiliary connectors and operations are kept cool using dual variable-speed Noctua fans. For greater ease of use, the Echo II will turn on and off with your host system.
