Unleash Pro-Level Power on Any Thunderbolt 3 Computer
Bridge the gap between modern portability and professional performance with the Sonnet Echo Express SEL. This compact, rugged Thunderbolt 3 expansion system is engineered for creative professionals who need to connect high-performance, low-profile PCIe cards—like audio interfaces, 10Gb Ethernet adapters, or 16Gb Fibre Channel cards—to their Thunderbolt 3 equipped Mac or Windows computer.
Whether you're working on a MacBook Pro in the field or an iMac in the studio, the Echo Express SEL unlocks capabilities previously reserved for bulky desktop towers. At its heart is a single PCIe 3.0 x8 slot housed in a durable aluminum chassis, designed to accommodate specialized cards up to 6.6 inches long. The system's dual 40Gbps Thunderbolt 3 ports deliver maximum throughput for the most demanding workflows.
The design is both powerful and intelligent. Use the first port to connect to your computer, and the second to daisy-chain up to five additional Thunderbolt peripherals, a 5K display, or two 4K displays—all through a single cable. This second port also supplies 15W of power for bus-powered devices. An intelligent, temperature-controlled fan keeps your valuable card cool under load while remaining whisper-quiet, perfect for noise-sensitive environments. For total peace of mind, Sonnet includes a 0.5-meter Thunderbolt 3 cable and a ThunderLok 3 retainer clip to prevent accidental disconnections during critical tasks. It’s the ultimate plug-and-play solution for your minimalist workflow.
