Netgear MSM4320 — 20-port AV-over-IP managed switch with 2.5G PoE++
The Netgear M4350-16M4V (MSM4320) is part of the NETGEAR AV Line, engineered and certified for professional audio/video over IP. It targets AV integrators, broadcast facilities, live-event production and commercial installations that need a robust core or access switch built for real-world AV deployments. With pre-defined AV profiles, an intuitive AV-focused interface and the NETGEAR Engage Controller, it dramatically simplifies setup of complex multicast networks. The rugged Neutrik etherCON connectors, redundant power and flexible interface-card slots make it especially suited to touring rigs, studios and permanent installs where reliability and fast, error-free configuration are critical to keeping productions running smoothly.
Rugged Neutrik etherCON & powerCON
Eight of the sixteen 2.5G ports use locking Neutrik etherCON connectors, and power comes in through two Neutrik powerCON connectors with C14 adapters for standard IEC cords. These ruggedised, latching connectors are the touring and live-event standard because they resist accidental cable pulls, vibration and repeated rigging. In practice this means data and power links stay seated even when the switch travels in a flight case or sits in a busy stage rack, so the operator faces far fewer dropped links mid-show and far less downtime chasing an unplugged cable during a live production.
AV-Over-IP Multicast Out of the Box
NETGEAR IGMP Plus delivers correct multicast behaviour for most AV-over-IP systems with little to no manual tuning, and pre-defined profiles cover the major audio, video and lighting protocols. Multicast misconfiguration is the classic cause of flooded networks and stuttering AV streams, and it normally demands deep networking expertise to fix. Because the switch handles this automatically, an AV operator without a full networking background can stand up a clean, reliable Dante, NDI or SDVoE network quickly, with smooth audio and video delivery and fewer support calls about glitches or dropouts.
Simplified AV Configuration GUI
A streamlined web interface lets factory-default AV settings or user-specified AV profiles be assigned to individual ports in just a few clicks, with multi-color front-panel LEDs reflecting each port's profile colour. This removes the need to hand-craft VLAN, QoS and multicast settings per port and makes the physical patching self-documenting. For the person running the system, that means faster commissioning, easy visual verification that each device is on the right network at a glance, and quicker troubleshooting when a connection needs to be checked or changed on site.
Redundant Power & Hitless Failover
Two internal 800W power supplies provide 530W of redundant base PoE budget (up to 1,130W), while Virtual Chassis stacking adds non-stop forwarding and hitless failover. If one supply or a stacked unit fails, the system keeps forwarding traffic without interruption. For broadcast, live events and mission-critical installs where a momentary outage can mean a lost feed or a dark display wall, this redundancy keeps powered cameras, displays and access points online and protects the production from single points of failure.
Flexible 25G Uplinks & Interface Cards
The switch ships with an APM414V card carrying 4x 25G SFP28 ports, and the slot accepts alternative cards: APM414C (4x 10G RJ-45), APM414SD and APM414LD with Neutrik opticalCON QUAD fibre connectors for multimode or single-mode runs. This lets the same chassis adapt to copper, short-reach or long-haul fibre backbones without replacing the switch. In practice the installation can be matched precisely to the venue's cabling and scaled later, protecting the customer's investment as the AV network grows from 1G edge devices up to 25G or 100G cores.
SMPTE ST 2110 & AES67 Clocking
The switch can act as an SMPTE ST 2110 Grandmaster Clock and Boundary Clock for AES67 and ST 2059-2 applications. Precise, network-distributed timing is essential in professional broadcast and high-end audio, where every device must stay locked to a common clock to keep video and audio frame-accurate. Built into the switch, this avoids adding separate grandmaster hardware and gives the facility tight, reliable synchronisation across cameras, audio nodes and processing gear, reducing lip-sync and timing artefacts in the finished output.
Quiet Mode for On-Set Use
Most M4350 models include a quiet mode that significantly reduces fan noise, and mounting ears are included for standard rack installation. Acoustic noise matters when a switch shares a room with microphones, a control booth or a quiet conference space, where conventional data-centre switches are too loud. With measured quiet-mode acoustics around 35.6dB, the unit can sit close to talent and operators without bleeding into recordings or distracting the room, making it practical for studios, houses of worship and boardrooms.
Lifetime Warranty & Layer 3 Routing
The switch carries a NETGEAR ProSAFE Limited Lifetime Hardware Warranty with lifetime next-business-day hardware replacement, and includes a full Layer 3 feature set with static, policy-based and dynamic routing. The routing capability lets a single device segment and route between multiple AV and control networks rather than needing a separate router. Combined with long-term warranty cover and fast replacement, this gives the end customer a dependable, future-proof core that can grow with the deployment and keeps total cost of ownership predictable.
