NETWORKING
79
■ A computer can be connected to the network
through its Ethernet port, but only for the purposes
of running the web app on the computer for
command and control over the network. You
cannot stream audio through the computer’s
Ethernet port. At this time, MOTU is working
closely with Apple on direct AVB support using the
network connectors.
■ All computers and interfaces on the network
have full access to each other.
■ MOTU employs a 1 Gbit AVB implementation in
its rack interfaces and the MOTU AVB Switch. The
switch allows routing of many audio channels
while maintaining low latency.
SETTING UP A MOTU AVB INTERFACE FOR
NETWORKING
Each MOTU AVB interface has the ability to
broadcast up to sixteen 8-channel streams to the
rest of the network. Conversely, it can “listen” to as
many as sixteen 8-channel streams from anywhere
else in the network.
For each device on the network, set it up for
network operation as follows:
1 In the MOTU AVB Control web app, choose the
device (item #1 on page 18).
2 Go to the Device tab (item #5 on page 18), go to
the AV B S t r e a m S e t u p section (item #25 on
page 19), and type in the number of 8-channel
input and output streams you want for that device.
3 Go to the AV B S t r e a m C o n n e c t i o n s section (item
#9 on page 19), and choose the network stream you
want the device to listen to for each bank.
4 Use the Routing tab to map specific I/O
channels within each MOTU AVB interface to its
network input and output streams, as explained in
the next section.
MAPPING AUDIO TO NETWORK STREAMS
Once you’ve configured a device’s AVB streams, as
explained above, use the Routing tab (page 20) to
map audio channels to network input and output
streams.
Input streams (coming from the rest of the
network) are listed across the top of the routing
grid. Expand the stream and click on the grid to
map incoming network channels to local
destinations, including physical outputs on the
device, computer channels (to a connected
computer), or mixer channels.
Output streams being broadcast to the rest of the
network are listed in rows along the left side of the
grid. Expand each stream bank and map
individual network output channels to local
sources, such as physical inputs on the interface,
channels coming from the computer, or channels
coming from the device’s mixer.
MAPPING COMPUTER CHANNELS TO
NETWORK STREAMS
If a host computer is connected to an interface
(through Thunderbolt or USB), mapping network
input and output streams is accomplished as
described in the previous two sections. Simply
enable AVB streams as desired, and map them to
computer channels in the Routing grid.
If, while mapping, you run out of computer
channels, enable more in the Computer Setup
section of the Device tab (item #22 on page 19). If
the computer is connected with Thunderbolt, you
can enable a maximum of 128 channels in and out.
If the computer is connected with USB,
performance will vary, depending on the sample
rate and other factors.
