The network switch has become one of the most important parts of a commercial AV system.
Cameras, microphones, encoders, decoders, displays, speakers, and control processors may all share the same network. If the switch cannot handle that traffic properly, users may experience dropped audio, frozen video, slow source changes, or devices that disappear without warning.
Choosing an AV network switch is not simply a matter of counting Ethernet ports. You also need to consider bandwidth, multicast traffic, Power over Ethernet, uplinks, protocol requirements, and future growth.
This guide explains what an AV switch does, which features matter, and how to choose the best network switch for AV projects.
What Is an AV Switch?
The term “AV switch” can mean two different things.
A traditional AV switcher selects between HDMI, USB-C, or other physical audio and video sources. An AV network switch, which is the focus of this guide, moves audio, video, control, and device data across Ethernet.
In an AV-over-IP system, the switch connects endpoints and directs traffic between them. The right model helps deliver stable device discovery, predictable multicast behavior, low-latency media, and enough power for compatible endpoints.
Why a Standard Network Switch May Not Be Enough
Some small audio systems can operate on a basic Gigabit switch. Larger commercial AV systems usually need more control.
Networked audio and video can create continuous, timing-sensitive traffic. Multicast streams may also reach ports that do not need them unless the switch is configured correctly.
Features such as IGMP snooping, an IGMP querier, Quality of Service, VLANs, and traffic monitoring help keep that traffic organized.
Audinate explains that multicast traffic can consume bandwidth throughout a network. Its Dante documentation also recommends IGMP snooping for Dante video running on 1Gbps infrastructure.
The goal is not to buy the most expensive switch. It is to match the switch to the AV platform, endpoint count, traffic pattern, and support plan.
How to Choose the Best Network Switch for AV Projects
1. Start With the AV Protocol
Identify the technology running across the network before comparing switch models.
Common examples include Dante, AES67, NDI, SDVoE, Q-SYS, Crestron NVX, and AVPro Edge MXnet. Each platform has its own requirements for bandwidth, multicast, clocking, VLANs, and configuration.
Choose a switch validated by the AV manufacturer or one with a tested profile for the protocol.
Strong hardware can still perform poorly when its settings do not match the endpoint ecosystem. NETGEAR, for example, provides AV profiles for protocols and platforms such as Dante, AES67, Q-SYS, NDI, NVX, and SDVoE.
2. Choose Managed Over Unmanaged
An unmanaged switch may work for a small, isolated system with simple unicast traffic.
A managed AV network switch provides control over IGMP, QoS, VLANs, port settings, security, monitoring, and troubleshooting. That makes it the safer option for most professional systems.
Purpose-built AV models often include preconfigured profiles. Enterprise switches can also work well, but they usually require an experienced network engineer to configure them for the AV platform.
3. Calculate Bandwidth and Uplink Capacity
A 1GbE port does not mean the whole network can carry every planned stream.
Many networked audio systems run comfortably on Gigabit Ethernet. Some compressed video platforms also use 1GbE, while higher-bandwidth or lightly compressed video may require 10GbE or faster connections.
NETGEAR advises matching the switch to the system’s bandwidth, using 1G for many audio applications and 10G or higher where video demands it. Audinate also lists wired Gigabit infrastructure as a common requirement for its networked audio software.
Calculate the bandwidth of each source and the total traffic crossing each uplink.
The best networking switch should have enough headroom for peak use, not only average use.
4. Count Ports and Plan for Growth
List every encoder, decoder, camera, DSP, microphone, control processor, wireless access point, and management device. Then add spare capacity.
Filling every port on day one leaves no room for another display, camera, or audio endpoint. A sensible design should also consider future rooms, additional signage, and possible system expansion.
Port count matters, but it should never be evaluated without bandwidth and PoE capacity.
5. Check the Total PoE Budget
PoE, PoE+, and PoE++ allow a switch to send power and data through the same Ethernet cable.
This can simplify installation for cameras, touch panels, microphones, speakers, encoders, decoders, and control devices.
However, a switch with many PoE ports may not have enough total power to run every device at full load.
Add the maximum wattage required by all powered endpoints. Compare that amount with the switch’s total PoE budget and leave some capacity for startup demand and future devices.
Cisco Catalyst models, for example, are available with different PoE levels, including models capable of delivering up to 90 watts to supported endpoints.
6. Plan Multicast, QoS, and VLANs
Many AV-over-IP platforms use multicast to send one stream to several receivers efficiently.
IGMP snooping prevents that stream from flooding unnecessary ports. An IGMP querier may also be needed to maintain multicast group membership, depending on the design.
QoS helps prioritize timing-sensitive audio, video, clocking, and control packets. VLANs can separate AV traffic from general business data, guest Wi-Fi, security cameras, voice systems, and other network services.
Crestron’s AV-over-IP network guidance includes multicast routing, VLAN tagging, and QoS as important considerations for larger networked AV deployments.
These settings should be planned by the AV integrator and IT team before installation. Poor segmentation or multicast configuration can break discovery and create difficult performance problems.
7. Review Uplinks, Stacking, and Redundancy
A switch may have enough endpoint ports but still become a bottleneck at the uplink.
Larger designs may need 10G, 25G, 40G, or 100G fiber connections between racks, floors, or buildings.
Stacking, link aggregation, redundant power, and separate primary and secondary audio networks may also be appropriate where downtime carries a serious operational cost.
These features are especially valuable for campuses, broadcast spaces, control rooms, event venues, and multi-building AV systems.
8. Consider Noise, Cooling, and Rack Layout
High-speed switches with large PoE budgets can generate heat and fan noise.
A loud switch may be acceptable in a remote equipment room but distracting inside a boardroom, recording space, classroom, or performance venue.
Review airflow, fan modes, rack depth, port orientation, power requirements, and service access.
Some purpose-built AV switches offer quiet or fanless modes and rear-facing network connections for cleaner AV rack installations.

Which AV Network Switch Is Best for Your Use Case?
For a small conference room or isolated AV system, the NETGEAR M4250 or a validated Q-SYS NS model may provide the right balance of simplicity, PoE, and AV-friendly configuration.
For a campus, control room, large digital signage network, or multi-switch video system, the M4350 provides more scaling, uplink, routing, and redundancy options.
For companies already standardized on Cisco networking, the Catalyst 9300 can be a strong choice when the IT team can configure multicast, QoS, VLANs, and endpoint security.
For a dedicated MXnet system, AVPro Edge switches can reduce commissioning work because they are designed around that ecosystem.
The best network switch for audio streaming is usually a managed Gigabit switch with adequate ports, dependable QoS, correct multicast control, and validation for the audio platform.
Wired Gigabit infrastructure remains a common baseline for Dante audio systems.
Common AV Switch Selection Mistakes
One common mistake is choosing by port count alone. Teams also overlook total PoE capacity, uplink bandwidth, fan noise, multicast settings, firmware support, and future endpoint growth.
Another mistake is assuming the most powerful switch will automatically deliver the best result.
The best network switches for business are the ones that match the AV protocol, traffic, scale, support model, and IT policies of the organization. Configuration matters just as much as hardware.
Build the Network Around the Complete AV System
A reliable AV network begins with bandwidth calculations, endpoint documentation, switch configuration, and realistic testing.
Select the switch alongside the encoders, decoders, cameras, audio devices, control platform, and business network. Treating it as a last-minute accessory creates avoidable risk.
The best network switch for AV projects is the model that meets today’s requirements while leaving a sensible path for expansion.
