AVB ETHERNET AUDIO INTERFACE SETUP
Use this setup if you want to use the UltraLite AVB
as an AVB Ethernet audio interface for a recent-
generation Mac (i.e. any Mac with a Thunderbolt
port on it). Mac OS X Yosemite (10.10) or later is
also required for AVB audio I/O.
■ Use a standard CAT-5e or CAT-6 cable.
■ Connect to the computer’s Ethernet port.
■ See “Operation as an AVB Ethernet audio
interface” on page 27.
■ No driver installation is necessary.
■ Enable at least one AVB stream (item #18 on
page 13).
■ Launch the Mac’s Audio MIDI Setup utility to
enable the UltraLite AVB and set the clock source
and sample rate.
■ The number of AVB audio channels that OS X
can handle depends on the speed of your Mac.
■ If applicable, see “Syncing multiple AVB audio
interfaces connected to a Mac” on page 41.
About CAT-5e cables
Use shielded CAT-5e or
CAT-6 cables, which are a
higher grade version of a
standard Ethernet cable.
They are available wherever
network cables are sold.
SETUP FOR TWO INTERFACES
Use this setup if you want to connect two MOTU
interfaces to your computer.
■ The connection to the computer can be either
USB or Thunderbolt, if you have a Thunderbolt-
equipped MOTU AVB interface such as the 1248,
8M, 16A or 112D.
■ Use a standard Thunderbolt cable. Place it at the
end of the Thunderbolt chain.
■ Use any standard CAT-5e Ethernet network
cable to connect the two interfaces together using
their NETWORK ports.
■ As an alternative, see “Setup for multiple
interfaces” on page 35.
OR
Thunderbolt is available on other
MOTU AVB-equipped interfaces, such
as the 1248, 8M, 16A and 112D.
