Scroll down to view these additional
Device tab settings.
19. In the Input/Output Banks sections,
you can disable any banks that you
are not using. Doing so hides them
from the routing matrix and mixer to
simplify operation. Doing so also
helps conserve DSP resources.
20. AVB is IEEE’s Audio Video Bridging
Ethernet standard for high-
bandwidth, low-latency audio
streaming over Ethernet. If your
1248, 8M or 16A is connected to a
2nd MOTU AVB interface through its
network port, or to an AVB switch for
access to an extended AVB network,
you can stream audio channels to
other destinations on the network.
AVB streams are handled in banks of
eight channels, so if you enable 16
out of 16 streams, that’s 128
channels (in, out, or both). See
chapter 9, “Networking” (page 75).
21. If you have AVB network input
streams enabled, connect them to
the output streams of other devices
on the network here.
22. In the Computer Setup section, you
can specify how many audio
channels you would like to be able to
stream to and from your computer,
up to 128 channels each way, simul-
taneously. For example, the 1248
has a total of 32 physical inputs and
34 outputs, so to be able to access
them all individually (with no
shared channels), you should
configure these two settings for 32
and 34, respectively. Map them as
desired in the Routing tab
(page 20). You can specify a higher
number of audio channels if you will
be streaming additional channels to
and from the AVB network or the
mixer.
23. Use these buttons to manually check
for and install updates for your
MOTU AVB device. For complete
details, see Appendix D, “Updating
Firmware” page (95). Updating from
a file can be done offline from your
computer, using an update you’ve
obtained through MOTU’s web site
or tech support department. The
Check For Updates button requires
that the computer (or device) you
are using to view your MOTU AVB
interface is connected to the inter-
net through a local network or WiFi.
Updating from the internet is easy
and convenient.
24. Use these buttons to reboot (restart)
the device, or restore its factory
presets.
25. The digital mixer in your MOTU AVB
interface supports up to 48
channels. If you don’t need that
many inputs, you can lower the
number here to simplify mixer and
routing operation and conserve DSP
bandwidth for effects processing.
