Download and run the MOTU AVB Audio
Installer
To download the latest MOTU AVB audio installer
for Mac or Windows, visit www.motu.com/avb.
Follow the directions that the installer gives you.
☛
We recommend that you run the software
installer before you connect your MOTU interface
to your computer and power it on. This ensures
that all driver components are properly installed in
your system.
AUDIO DRIVERS
On the Mac, no USB audio driver is installed
because your MOTU interface is USB audio class
compliant, and USB audio operation is handled by
Mac OS X. On Windows, the installer provides
USB ASIO and Wave drivers.
MOTU AVB USB ASIO Driver
On Windows, to enable your MOTU interface in
your ASIO host software, choose the MOTU AVB
USB ASIO driver.

MOTU AVB DISCOVERY APP FOR MAC
On the Mac, the MOTU AVB Discovery app is
installed in your Mac’s applications folder; a
shortcut is installed for it, too (as shown on page
page 13). It locates all MOTU AVB interfaces
connected to the Mac, either directly through USB
or on your network, and displays them in a list.
Choose an interface to access its settings through
the web app (“MOTU AVB Control Web App” on
page 13).
MOTU AVB WEBUI SETUP FOR WINDOWS
On Windows, the installer provides a MOTU AVB
WebUI Setup shortcut found on the Windows
desktop or in Start menu> All Programs> MOTU .
Use this shortcut to access the MOTU AVB Control
web app directly in your favorite web browser.
MOTU AVB USB CONTROL PANEL
On Windows, the MOTU AVB USB Control Panel
(
Start menu> All Programs> MOTU ) provides
three tabs: Status, Buffer Settings and Info. The
Buffer Settings tab provides several basic settings
for the AVB USB driver.

tab.
USB Streaming Mode
USB Streaming Mode (Figure 3-2) determines how
frequently the USB driver transfers audio. Smaller
settings reduce latency. This setting determines the
latency for standard Windows audio applications
(such as Media Player). For further information
about latency, see “Reducing monitoring latency”
on page 59.
ASIO Buffer Size
ASIO Buffer Size (Figure 3-2) determine how much
delay you hear when monitoring live inputs
through your audio software: larger buffers
produce more delay; smaller buffers produce less.
For complete information about this setting, see
“Working with Host Audio Software” on page 55.
