STAND-ALONE OPERATION
All settings, including mix settings and device
settings, are saved in the LP32’s memory. They
remain in effect even when the interface is not
connected to a computer. This allows you to use the
LP32 as a stand-alone mixer. You can make
adjustments to any setting at any time from the web
app running on a device that has a network
connection to the LP32, as explained in “Setup for
web app control” on page 37.
Setting Explanation
Serial/UID Unique AVB network identifier and serial
number that can be used for trouble-
shooting and registering your device at
motu.com/register.
IP address The unique network address for the unit.
Type this address into your web browser
to access the unit’s settings in the MOTU
Pro Audio Control web app.
AVB Indicates whether AVB networking is
currently enabled or disabled. For exam-
ple, AVB could be disabled because a
non-AVB switch is being used. When
AVB is disabled, audio streaming over
the network is disabled.
