The MOTU AVBSwitch is a specialized, five-port Ethernet switch engineered exclusively for Audio Video Bridging (AVB) networks, which are designed for professional, low-latency, synchronous streaming of audio and video over standard IEEE 802.1 Ethernet. Unlike a conventional data switch, this device is built to comply with the strict timing and prioritization requirements of the AVB protocol suite, ensuring that digital audio samples and video frames are delivered with deterministic latency and perfect synchronization across all connected devices on the network. It serves as the central nervous system for small to medium-scale AVB audio systems, connecting compatible interfaces, mixers, and endpoints like the MOTU 1248, 16A, or 24Ai/O, to form a single, tightly integrated audio network.

The switch's core function is to manage network traffic with Time-Sensitive Networking (TSN) features, which are the foundation of AVB. It establishes a common clock across the network and reserves dedicated bandwidth for AVB streams, guaranteeing that critical audio and video data is transmitted without interruption from other network traffic, such as control data or file transfers. This results in rock-solid, sample-accurate synchronization of all channels across all devices, which is essential for multi-channel recording, live sound, and broadcast applications where latency and jitter are unacceptable. The five ports provide a compact and efficient hub, allowing for a star topology that is simple to set up and troubleshoot.

Designed for reliability in studio and live environments, the MOTU AVBSwitch typically features a rugged metal housing, silent operation (often fanless), and a straightforward plug-and-play design that requires minimal configuration when used within a compatible AVB ecosystem. It represents a critical infrastructure component for audio professionals adopting AVB as their primary digital audio transport, offering a future-proof, network-based alternative to traditional point-to-point digital audio cabling like AES3 or MADI. By providing a dedicated, standards-compliant network backbone, this switch enables scalable, high-channel-count audio systems with exceptional stability and synchronization.
