Sonnet Echo III Desktop: Pro-Grade Thunderbolt 3 to PCIe Card Expansion
Unlock the full potential of your professional workflow with the Sonnet Echo III Desktop. Modern Thunderbolt™ 3 computers offer incredible power and portability, but often at the cost of internal expansion. The Echo III is the definitive solution for creative professionals, bridging the gap by allowing you to connect up to three full-length, professional PCIe cards to your Mac® or Windows® PC through a single, lightning-fast 40Gbps Thunderbolt 3 cable.
Designed for the most demanding applications in pro audio, video capture, 10Gb+ networking, and data storage, the Echo III provides the critical I/O and processing power you need. It features one x16 and two x8 PCIe 3.0 slots, delivering up to 2750 MB/s of bandwidth to handle your most resource-intensive cards. For audio engineers, the Echo III is a game-changer, offering a dedicated mode to support up to three Avid® Pro Tools | HDX cards, transforming your computer into a formidable recording and mixing powerhouse.
Sonnet engineered the Echo III for unwavering stability and quiet operation in professional environments. A robust 400W internal power supply, complete with a 75W auxiliary power connector, ensures even the most power-hungry cards perform flawlessly. To maintain a pristine studio atmosphere, two ultra-quiet, temperature-controlled Noctua fans (rated at a near-silent 17 dBA) keep your components cool without adding distracting noise. The second Thunderbolt 3 port enables you to daisy-chain up to five additional Thunderbolt peripherals, creating a powerful, streamlined workstation. Housed in a rugged, road-ready aluminum chassis, the Sonnet Echo III Desktop is the essential upgrade to reconnect you with the tools that define your craft.
