20. AVB is IEEE’s Audio Video Bridging
Ethernet standard for high-
bandwidth, low-latency audio
streaming over Ethernet. If your
MOTU interface is connected to a
2nd MOTU interface through its
network port, or to an AVB switch for
access to an extended AVB network,
you can stream audio channels to
and from other devices on the
network. AVB streams are handled
in banks of eight channels, so if you
enable 2 streams, that’s 16 channels.
See chapter 10, “Networking”
(page 87).
21. If you have the AVB network input
stream enabled (20), connect them
to the output streams of other
devices on the network here. This is
how you route audio from the other
devices to the LP32.
22. 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.
23. Configure the optical ports for either
8-channel ADAT or stereo TOSLink.
At 88.2 or 96 kHz, the ADAT setting
supports 4-channel SMUX format.
See “Optical I/O” on page 42. When
the interface is set to a 1x sample
rate (44.1 or 48 kHz), the 2x SMUX
Mode menus are grayed out because
they don’t apply to 1x operation.
24. The digital mixer in the LP32
supports up to 48 channels at 44.1
or 48 kHz. At higher sample rates,
the maximum number of supported
channels is lower, due to finite DSP
resources. If you don’t need 48
inputs (or the maximum available),
you can lower the number here to
simplify mixer and routing opera-
tion and conserve DSP bandwidth
for effects processing.
