Audio Video Bridging (AVB) establishes itself as an Ethernet extension of the IEEE 802.1 standard designed for real-time media. Whereas a typical network switch merely routes data packets, AVB adds a logic oriented towards professional audio/video: synchronization, low latency, and stable behavior under network load.
The MOTU AVB Switch positions itself as a simple and robust tool to build a coherent AVB network: it connects multiple compatible devices (audio interfaces, converters, AVB endpoints, or even other AVB switches) while offering a practical sixth port for integration into a standard Ethernet network. This approach is ideal for evolving an existing infrastructure without starting from scratch.
This switch is aimed at users who want to transition (or prepare to transition) to audio over IP and AVB stream transport, with typically "pro" requirements: stability, predictability, and synchronization. It suits studios (control rooms, recording rooms, digital patching), as well as live sound, broadcast, or fixed installations (performance venues, houses of worship, cultural centers, multipurpose rooms).
The benefits are twofold: on one hand, you simplify cabling by switching to Ethernet (lengths, distribution, scalability); on the other, you maintain logic adapted to sensitive streams. In practice, you can group multiple AVB devices on the same network, organize your audio and video distribution, and preserve the essential temporal coherence for multi-room systems and synchronized configurations.
The MOTU AVB Switch provides five AVB ports at 1 Gigabit to directly connect any AVB-compatible device, including the possibility to expand your setup by linking other AVB switches. This architecture facilitates scaling: you can start with a few devices, then expand the network as your needs grow (new interfaces, new distribution points, new zones).
In many environments, the network serves more than just audio and video. The additional Ethernet port allows linking to a broader infrastructure (IT, control, network access), while maintaining a clean AVB base for real-time streams. And if your usage evolves, note that the AVB ports can also be used for Ethernet, adding appreciated flexibility during network design or troubleshooting.
Where a standard switch is designed for "best effort" IT exchanges, AVB targets behavior adapted to audio/video constraints: controlled latency, prioritization, and managed network resources to avoid surprises during activity peaks. This is precisely what makes the difference when transporting multiple simultaneous streams and maintaining constant stability, whether in studio sessions, live recording, or broadcasting.
Thanks to its 12 front-panel activity LEDs, network status is visual and quick to diagnose: activity, links, traffic presence. Its compact form factor and DC power supply facilitate integration into a rack, workstation, technical bay, or close to the stage. In summary, it's a discreet tool designed to remain "transparent" daily while playing a central role in your AVB infrastructure.
