The Sonnet Echo II DV Desktop Thunderbolt Expansion System is a high-performance, professional-grade solution designed for users who need to connect PCIe cards to Thunderbolt-equipped computers. Perfect for video professionals, media production teams, and engineers, this desktop expansion chassis allows for the installation of two full-length, full-height, single-width PCIe cards—delivering exceptional flexibility and performance.
Unlike standard expansion enclosures that split a single Thunderbolt connection across multiple slots, the Echo II DV Desktop provides dual Thunderbolt interfaces. This design enables each PCIe slot to receive its own dedicated bandwidth, ensuring optimal performance without bottlenecks. When each Thunderbolt interface is connected to separate ports on a host computer, each slot can deliver up to 2880 MB/s of PCIe bandwidth—ideal for data-intensive applications like video capture, high-speed storage, or networking cards.
Power delivery is equally robust. The system includes a built-in 400W power supply and two 75W auxiliary power connectors, providing ample headroom for demanding PCIe cards that are not GPU-based. The inclusion of dual temperature-controlled Noctua fans ensures ultra-quiet, efficient cooling, keeping critical components at safe operating temperatures even under sustained workloads.
The Echo II DV Desktop is compatible with macOS, Windows, and Linux operating systems and supports a wide variety of Thunderbolt 3 and Thunderbolt 4-equipped computers, including Apple M series Macs, Intel-based Macs, and Windows PCs. This makes it highly adaptable across different hardware ecosystems and professional workflows.
Its durable construction, automatic power syncing with the host computer, and compact desktop form factor make the Echo II DV a versatile choice for studios, mobile production environments, and high-performance workstations. It's the ideal solution for professionals who need to expand their system capabilities without compromising speed or reliability.
