The Single-adapter Solution for Connecting to Pro Tools | Carbon
Thunderbolt Gigabit Ethernet Adapter for Macs with Thunderbolt Ports
The Avid® Pro Tools | Carbon audio interface for music production has been described as a creative game changer; its innovative use of eight onboard HDX processors and a custom FPGA enable you to track and monitor with near-zero latency when using AAX DSP plug-ins. Because Carbon connects to your Mac® over Ethernet using a proprietary version of AVB (Audio Video Bridging, aka IEEE 802.1), you’ll have to use an AVB capable Thunderbolt™ Gigabit Ethernet adapter if your computer doesn’t have onboard Ethernet. The Avid Qualified Sonnet Thunderbolt AVB adapter is your single-adapter solution for connecting your Mac with Thunderbolt 4 or Thunderbolt 3 ports to the Carbon interface.

Avid-Compliant Ethernet Adapter – Connect to Other Devices On a Network
Beyond its support for the Pro Tools | Carbon interface, the Sonnet Thunderbolt AVB Adapter enables you to add your Mac as an endpoint in an AVB network and connect to other devices such as audio interfaces, mixers, plug-in processors, personal monitor stations, stage boxes, speakers, speaker processors, and others. Audio Video Bridging support makes the adapter perfect for use in pro audio and video applications where synchronization of data streams is critical.

Simple Setup – Drivers and Configuration App Built Into macOS
The basic drivers that support the Sonnet Thunderbolt Adapter are included in macOS®. Basic configuration takes place in Network control panel, while configuration for use in AVB applications is handled in the Audio MIDI Setup application and control software.
