Pro Rackmount Enclosure and PCIe Card Expansion for Mac Studio
xMac Studio/Echo III
3U Rackmount Enclosure with Modular 3-slot Thunderbolt to PCIe Expansion
Expand Your Mac Studio Workflow – Connect Three PCIe Cards
A Mac Studio delivers phenomenal processing power, outperforming computers many times its size and price – and includes a robust selection of ports. But how do you integrate a Mac Studio into off-the-desk professional workflows and expand its connectivity beyond what’s available out of the box?
Sonnet xMac Studio/Echo III integrates a Mac Studio (sold separately) into a compact, rugged steel 3U rackmount enclosure with a 3-slot Thunderbolt™ to PCIe card expansion module to support diverse audio and video application workflows.

Designed for Expansion: Mac Studio + PCIe Cards
For many creative professionals, PCIe card expansion for connecting specialty I/O and processing cards to handle audio and video post-production projects is not an option — it’s a necessity! Sonnet designed xMac Studio for professional workflow flexibility. The xMac Studio/Echo III provides space to securely house a Mac Studio with Sonnet’s Echo III 3-slot PCIe card expansion module preinstalled in the enclosure’s expansion bay.


Configured with Echo III Module
Versatile Three PCIe Card Expansion
Echo III Module features three PCIe 3.1 slots and supports virtually all Thunderbolt-compatible, non-GPU PCIe cards ranging from low-profile, half-length to full-height, full-length sizes. For a list of supported PCIe cards refer to Sonnet’s PCIe Compatibility Chart.
40 Gbps Thunderbolt Interface
Module offers two 40 Gbps Thunderbolt ports, with a single 40 Gbps Thunderbolt 3 interface delivering 2800 MB/s of PCIe bandwidth to the installed PCIe card(s).
400W of Power
A built-in 400W power supply (with 75W aux. power connector) supports power-hungry cards including Avid Pro Tools | HDX, AJA Kona 5, Blackmagic DeckLink 4K Extreme 12G, and DeckLink 8K Pro G2, and Deltacast 12G/4C cards. Systems power on and off automatically with the connected Mac Studio.
Quiet Operation
Dual temperature-controlled, variable-speed Noctua fans (rated at 17 dBA) offer ultra-quiet operation.
Control and Connect – Easy Access to Mac Studio and PCIe Card Expansion Module
xMac Studio/Echo III places your Mac Studio behind a quick and easy to remove front panel. Convenient front panel operation allows you to turn on the computer with its own dedicated front power button, connect USB devices through a 4-port USB-A hub, and access the Studio’s front ports and SD card slot. Three rear panel locking thumbscrews allow you to easily pull out and access the Echo III Module and PCIe cards through the front without removing the front panel. The xMac Studio design enables you to connect and disconnect cables without needing to remove the computer from the enclosure.
xMac Studio/Echo III is designed to allow normal WiFi and Bluetooth wireless operation in most configurations (depending on rack type and position in rack), so you can use wireless devices and iOS device control apps.

Cool Design. Go with the Airflow – Supports the Mac Studio Thermal Design.
xMac Studio/Echo III secures your Mac Studio without trapping it in recirculating hot rack air, supporting its thermal design to keep it as cool in a rack as out on a desk. Ventilation holes on the enclosure’s front panel plus an enclosed chamber beneath the Mac Studio ensures the computer’s ability to draw in cool air through its base, while a completely open back enables it to expel warm air out the back unimpeded.

Space for SSDs – Secure Two Thunderbolt or USB SSDs Under the Mac Studio
xMac Studio/Echo III provides space beneath the computer to house two Thunderbolt or USB SSDs (sold separately) up to 3.2 inches wide by 0.75 inch tall. Simply remove the rear access panel, apply the supplied adhesive-backed magnet to the bottom of the SSDs, insert the SSDs and connect them to the computer, and then reinstall the panel. The space is also suitable for other thin, bus-powered devices.

Road Trip Ready – Workflows on the Go
Do you need to take your workflow on the road? xMac Studio/Echo III is a perfect travel solution. Its 16.5-inch mounting depth – plus firm rubber cushions that securely hold your Mac Studio in place during transport – make xMac Studio/Echo III ideal for use in molded rack cases from Gator Cases, fly racks from SKB Cases, or most any travel rack.
