Scroll down to view these additional
Device tab settings.
19. In the Input/Output Banks sections,
you can disable banks that you are
not using. This hides them from the
routing tab and mixer to simplify
operation and conserve DSP power.
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.
See chapter 9, “Networking”
(page 79).
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 32 physical inputs and 34
outputs, so to be able to access them
all individually, 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. The Computer Volume Controls
setting is only available when your
MOTU interface is connected to a
Mac using Thunderbolt. When
enabled, this option allows you to
control the volume of From
Computer channels 1-2 using the
volume controls on your Mac’s
keyboard.
24. Use these buttons to manually check
for and install updates for your
MOTU AVB device. For complete
details, see Appendix D, “Updating
Firmware” page (99). Updating from
a file can be done offline from your
computer, using an update you’ve
obtained through MOTU’s web site.
The Check For Updates button
requires that the computer (or
device) you are using to view your
MOTU AVB interface is connected to
the internet through a local network
or WiFi.
25. Use these buttons to restart the
device or restore its factory presets.
26. In the Optical Setup section, you can
choose between 8-channel ADAT or
stereo TOSLink formats for bank A
input and output, independently. At
882. or 96 kHz, the ADAT setting
supports 4-channel SMUX format.
See “Optical” on page 46.
27. 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.
