The NETGEAR NMS-NG10GPX-AVB (NETGEAR model GSM4212PX) switch is designed to seamlessly integrate with Cambridge Qt X sound masking solutions. Equipped with 8 PoE+ Ports, the NMS-NG10GPX-AVB switch powers up to eight Qt X controllers, including the Qt X 800’s. There are also two additional gigabit ports for other functions, such as trunking.


  • Preloaded with AVB License: The switch comes preloaded with the necessary AVB license, enabling it to pass AVB network audio signals without additional adjustments.
  • Out-of-the-Box Configuration: The system is preloaded with a configuration file for seamless integration with Dante or AVB, ensuring optimal performance with Qt X right out of the box.


  • Simplified System Deployment: The PoE+ support allows Qt X 800 devices to be installed in the ceiling/plenum, eliminating the need for a dedicated power source in the ceiling.
  • Scalability: Up to six NMS-NG10GPX-AVB switches can be connected together without requiring further network design considerations.
