About the MOTU AVB Switch

IEEE 802.1 compliant AVB networking

Audio Video Bridging (AVB) is the exciting new 
IEEE 802.1 extension to Ethernet specifically 
engineered for real-time, low-latency, fully 
synchronized streaming of audio and video over 
Ethernet. AVB fulfills the promise of a true A/V 
standard that brings together the worlds of 
networking technology and professional audio/
video.

Use the MOTU AVB Switch for all your AVB needs

The MOTU AVB Switch™ allows you to quickly 
and easily build an AVB-compliant audio (or 
video) network, with six 1-Gigabit AVB ports for 
any AVB devices (even other switches), plus 
compatibility with standard Ethernet. Enjoy the 
many benefits of AVB, including plug-and-play 
operation, guaranteed quality of service, and self-
regulated network resource management.

Plug-and-play operation

Connect MOTU AVB devices with standard 
CAT-5e or CAT-6 cables and go. The MOTU AVB 
Switch supports automatic device discovery and 
network bandwidth management among 
connected AVB devices. No IT expertise required.

Standard cabling

Use standard CAT-5e or CAT-6 Ethernet cables up 
to 100 meters long between the MOTU AVB 
Switch and other AVB devices or switches.

1-Gigabit operation

1-Gigabit operation means you make the most of 
what AVB has to offer, with very high audio 
channel counts and very low network latency.

Guaranteed Quality of Service (QoS)

In an AVB Ethernet network, all existing audio 
and video streams are maintained, regardless of 
other network traffic.

Network-wide clock and sync

AVB provides a network-wide time base for 
better-than-sample-accurate phase lock across all 
connected audio devices. Timing accuracy is 
down to the nanosecond. In a MOTU AVB 
system, network-wide sync can be established 
with one click.

Support for standard Ethernet

AVB can coexist with standard Ethernet, for 
connecting standard Ethernet devices like Wi-Fi 
routers, Ethernet hubs, and even entire Ethernet 
networks in your home, office or studio. Any of 
the ports on the MOTU AVB Switch support 
standard Ethernet. If needed, any port can be 
configured for non-AVB operation.
