23. In the Optical Setup section, you can
choose between 8-channel ADAT or
stereo TOSLink formats for bank A
input and output, independently. At
88.2 or 96 kHz, the ADAT setting
supports 4-channel SMUX format.
See "Optical" on page 52.
24. Your MOTU interface can resolve to
SMPTE time code, also referred to as
LTC (Longitudinal Time Code), by
choosing LTC from the Clock Mode
menu (item 14 on page 18). From
the LTC Input Source menu (24
above), choose the analog or digital
input that is receiving the time code.
If you would also like to send time
code (LTC) to the computer, where it
will be converted to MIDI Time Code
(MTC) for resolving your DAW or
other software to MTC via OS X Core
Audio (a Mac-only feature), choose
an audio channel you are not using
for other purposes from the
M O T U P R O A U D I O C O N T R O L W E B A P P
23
Computer Channel for LTC-to-MTC
Conversion menu; otherwise, leave it
set to None. Choose the desired
frame format, or use the Enable
Format Autodetect to automatically
detect the frame format of the
incoming time code. When Enable
Jam Sync is turned on, your interface
will continue to operate under its
own clock and continue LTC-to-MTC
conversion, even after it stops
receiving time code. Click Stop Jam
Sync to exit this mode. For further
details about time code sync, see
"Syncing to SMPTE time code (LTC)"
on page 60 and "LTC-to-MTC conver-
sion" on page 80.
25. Use Restore Factory Presets to restore
the factory presets.
26. Use Set Password to password-
protect the interface on the
network. All settings are blocked,
except for aux bus mixing, as shown
above (26). This allows musicians to
access their personal monitor (aux)
24
mixes from their mobile
devices, while all other device
settings remain blocked. To
clear the password, log in and then
click Clear Password. If you forget the
password, you can clear it in the
Settings menu in the front panel LCD
(see page 71) with either the Clear
Password setting or by doing a
factory reset with the Factory
Default setting.
27. The System Information section
displays information about your
MOTU device, including the
firmware version and network IP
address.
28. Use these buttons to manually check
for and install updates for your
MOTU AVB device. For complete
details, see Appendix D, "Updating
Firmware" (page 125). Updating
from a file can be done offline from
your computer, using an update
you've obtained through MOTU's
web site or tech support depart-
25
26
ment. The Check For Updates button
requires that the computer (or
device) you are using to view your
MOTU AVB interface is connected to
the internet through a local network
or WiFi.
29. Click Reboot to restart the interface.
30. When the Computer Volume Controls
option is enabled (a Mac only
feature), the Audio MIDI Setup
utility in MacOS provides volume
control for each output channel to
your MOTU audio interface. In
addition, the volume controls for
your Mac (on your computer
keyboard) will control the channels
you've designated for computer
output in Audio MIDI Setup, if any.
Be careful when toggling this
setting because sudden changes in
your computer volume can result.
