Today's laptop, mini desktop, and all-in-one computers pack tons of power. In fact, they're more powerful than the full-sized towers of yesteryear. To top it off, thanks to modern Thunderbolt connectivity, today's computers support a vast array of peripherals with blazing-fast speeds. But what's missing are PCIe expansion slots and extra storage — must-have features for creative professionals. That's where the Sonnet Technologies DuoModo xMac mini/Echo III Rackmount System comes in. This cutting-edge Dual-module enclosure features an Echo III Module that allows for the connection of three full-length PCIe cards to your Thunderbolt 3-equipped computer, and an xMac mini Module that provides the ultimate Mac mini upgrade with NVMe storage expansion and additional peripheral connection ports. If you've been eyeing a high-powered portable computer, but don't want to part with your PCIe-based rig, the DuoModo Rackmount System is the perfect solution.

Easy expansion via a single Thunderbolt 3 port

The Echo III Module makes expanding your computer a breeze. Simply plug it into one of your machine's Thunderbolt 3 ports, and you'll benefit from 2750 MB/s of PCIe bandwidth. The Echo III accommodates three full-height, single-width cards, or one double-width card plus one single-width card. At Sweetwater, we've found that this expansion system supports every Thunderbolt 3-compatible, non-GPU card — including Avid HDX. The Echo III Module is also integrated with a 400-watt power supply that includes 75 watt of auxiliary power, and saves energy by automatically powering on and off with your computer. This system's dual temperature-controlled, variable-speed Noctua fans are rated at 17dBA for whisper-quiet cooling. A rugged steel housing rounds out the DuoModo's impressive design.

The latest generation of Mac mini and iMac Pro computers are multi-core powerhouses. They boast all the power your hungry Pro Tools sessions need. Unfortunately, they lack PCIe ports. In the past, this would make them unsuitable for Pro Tools HDX systems. But now, thanks to the Sonnet Technologies DuoModo xMac mini/Echo III Rackmount System, any computer with a Thunderbolt 3 port is fair game. The Echo III Module supports up to three HDX PCIe cards, and it has been tested and qualified for use with Avid Pro Tools.
