DEVICE PRESETS AND AVB STREAM
CONNECTIONS
When you save a preset for a MOTU device (item 7
on page 12), any AVB stream connections that it
has established with other devices on the network
are now included with the saved preset. When you
recall the preset, those saved stream connections
are restored, as long as the other devices are still
present on the network and broadcasting the same
streams. If the other device is not present (or
perhaps turned off), its streams will be reported as
“offline”.
In general, if you have multiple devices on a
network with interconnecting AVB streams, and
you wish to preserve the state of the network, it is
recommended that you save a device preset for
each device on the network. Doing so will allow
you to faithfully restore the entire network stream
configuration by recalling each device’s saved
preset.
BRIDGING TO ETHERNET
The Ethernet port on the MOTU AVB Switch
allows you to connect standard network devices,
such as:
■ A Wi-Fi router
■ An Ethernet hub or switch connected to a local
home, studio, or office network
■ Any other standard networking device
THE MOTU AVB SWITCH
The heart of a MOTU AVB network is the MOTU
AVB Switch (sold separately). For a brief overview
of the switch and its features, visit:
