The Netgear AV Line M4250 GSM4248PX 40x Port Gigabit PoE+ Managed Switch has been built from the ground up for the growing AV over IP market, combining years of networking expertise in AV with M4300 and M4500 series with best practices from leading experts in the professional AV market. AV codecs generally use 1Gbps or 10Gbps per stream and the AV Line of M4250 targets the widespread 1Gbps codecs. PoE+, Ultra90 PoE++ and rear-facing ports ensure a clean integration in AV racks. M4250 switches come pre-configured for standard audio and video signals. When requirements are more specific, an AV user interface offers customization with port-based profiles. For audio Dante, Q-SYS and AES67 profiles are available, as well as an AVB profile requiring an AVB license sold separately. For video, the M4250 offers profiles for NVX, AMX, Q-SYS, NDI, Dante, etc. as well as audio/video/control mixed profiles. When multiple switches are used, NETGEAR IGMP PlusTM brings automation for you to just connect them together, or with M4300 and M4500 switches.

Extended AV features:

  • Dedicated AV web-based GUI
  • Interface for more specific AV installations
  • Color-based AV profiles can be applied to the different ports
  • Dante, Q-SYS, AES67, and AVB audio profiles

Audio Video Bridging (AVB) services

  • AVB is one of the many features designed into the M4250 product line
  • AVB is an industry-standard for transporting content over a network
