NETWORKING
77
computer system. Despite the distance, the two
interfaces operate as a seamless system, controlled
from your computer or iPad.
Studio installation
A studio installation of three to five interfaces can
be handled with a single MOTU AVB Switch. See
“Setup for three to five interfaces” on page 37.
Networking is ideal for studio installation because
you can position interfaces at strategic locations.
Running cables becomes much simpler and more
cost effective. Not only does a setup like this give
you access to all I/O from your computer, even
multiple computers, you can also route audio from
any input to any output across devices with near
zero latency. You can also route audio from one
computer to another with very low latency. As a
simple example, you could deploy several
interfaces in a studio as follows:
Large studio facility
In a larger studio facility, you could build audio
network neighborhoods similar to the studio
installation described earlier in multiple rooms,
even multiple floors, with multiple computers and
WiFi control from anywhere in the facility. All
computers and devices can see each other and you
can stream audio anywhere on the network with
near-zero latency, as if any two devices were
connected directly to each other.
Concert systems
Concert systems must be flexible so they can adapt
to each new venue while on tour. Because of its
modular nature, AVB networking allows you to
design systems that are scalable and easy to adapt
to each venue. You can easily bring devices on and
offline, rerouting audio stems as needed.
Because MOTU AVB networking employs a star
configuration, instead of daisy-chaining, you can
set up backup computer playback systems on a
shared network. For example, in a concert setting,
if one computer system goes down, the backup
system can be brought on line instantly through the
same network infrastructure.
Traditionally, live performance setups often have
separate domains for front of house mixing,
monitor mixing, computer backline, and other
systems. With MOTU AVB networking, these
systems can be unified on the same network,
opening up many possibilities for shared resources
and mixing/routing responsibilities, especially
from multiple sources (laptops, iPads, tablets, etc.)
MOTU AVB networking handles audio in
convenient 8-channel stems, making large-scale
network management more manageable. MOTU
AVB’s very low latency makes it particularly
suitable for line arrays and sound reinforcement.
Large-scale venues
With long cable runs and industry standard
networking infrastructure, MOTU AVB systems
are well-suited for large-scale commercial
installations such as arenas, stadiums, theme
parks, clubs, casinos, houses of worship, broadcast
facilities, schools, universities, and so on. Audio
streams can travel long distances with sub-
millisecond latency through as many as seven
switches. Audio can be distributed from a
centralized location to anywhere in the venue.
