SETUP FOR AVB ETHERNET AUDIO
INTERFACE OPERATION
Your MOTU hardware can serve as an Ethernet
audio interface when connected to a recent
generation AVB-equipped Mac. You can then use
your MOTU interface as a standard multi-channel
audio interface with any Core Audio compatible
host software running on the Mac.
For Ethernet audio interface operation, you need:
■ A recent Mac (any Mac that has a Thunderbolt
port on it)
■ OS X El Capitan (10.11) or later
■ Firmware version 1.2.5 or later in your MOTU
interface
Ethernet connection to the Mac
As shown on page 34, connect the network port on
your MOTU interface to the Ethernet port on the
Mac using a standard, high-grade (CAT-5e or
CAT-6) network cable up to 100 meters in length.
☛ If your Mac doesn’t have an Ethernet port, you
can connect your MOTU interface via Ethernet
using a Thunderbolt-to-Ethernet adapter. Ethernet
might be preferable over Thunderbolt because the
Ethernet cable can be up to 100 meters long, using
standard Ethernet cabling (which is very
affordable).
☛ USB-to-Ethernet adapters cannot be used
because the Mac’s USB chip set does not support
AVB Ethernet.
Alternately, you can connect both the Mac and the
interface to an AVB-compatible Ethernet switch.
Web app setup
To set up your MOTU device as an AVB Ethernet
audio interface:
1 Launch the MOTU Discovery app. From the
Settings menu (circled in red below), choose
Launch Mac Virtual Entity, and from the sub-menu
choose the Ethernet port to which your MOTU
AVB interface is connected. It should now be
checked.
Figure 4-6: Enabling AVB connectivity to the Mac.
2 After completing step #1 above, the Mac will
appear in the AVB device list in the MOTU AVB
web app, as shown below. PLEASE NOTE: it may
take several minutes for the Mac to appear in the
list, the first time you set this up. After the first
time, though, you won’t experience any delays.

app.
3 From the Configuration menu (Figure 4-7),
choose the channel mode for the Mac that best fits
your workflow.
