Unlock Pro-Level Performance: Echo II DV Dual-Slot Thunderbolt PCIe Expansion System
Modern computers, from Apple M-series Macs to ultra-light Windows laptops, have sacrificed internal expansion slots for portability. For creative professionals, this presents a major workflow bottleneck. The Sonnet Echo II DV is the definitive solution, a professional-grade Thunderbolt™ to PCIe card expansion system engineered to reconnect you with the high-performance tools your craft demands. Whether you rely on multi-card Pro Tools | HDX systems, advanced 8K video capture cards from AJA and Blackmagic Design, or other specialized PCIe hardware, the Echo II DV delivers the dedicated performance, robust power, and reliable connectivity you need to work without compromise.
At the core of the Echo II DV lies a revolutionary design advantage: two independent Thunderbolt interfaces, one for each PCIe 3.1 slot. Unlike chassis that share a single controller, this architecture provides a dedicated, uncompromised data lane for each installed card when connected to a computer with multiple Thunderbolt controllers (like all Apple silicon Macs). This completely eliminates bandwidth conflicts, ensuring that your audio DSP card and your video I/O card can both operate at their maximum potential simultaneously. Say goodbye to performance sharing and hello to pure, dedicated speed for each of your critical tools.
Power-hungry professional cards are no match for the Echo II DV. It features a whisper-quiet, temperature-controlled fan and an integrated 400W universal power supply, complete with two 8-pin (6+2) auxiliary power connectors that deliver up to 75W of power each. This provides ample, stable energy for the most demanding non-GPU cards that require supplemental power. The system is also intelligently designed to power on and off automatically with your computer, streamlining your workspace and conserving energy. As your needs grow, the Echo II DV can be seamlessly integrated into Sonnet's DuoModo™ modular enclosure family, making it a flexible and future-proof cornerstone for any professional workstation.
