Quick Reference: MOTU Audio Setup

CHAPTER
Click the General tab to access these settings.
Check this option if you would like the MOTU
Audio Setup icon to appear in the application
dock as soon as a MOTU interface is detected
(switched on, plugged in, etc.)
If the video features of the V4HD are enabled
(see "Enable Video" on page 50), the only
choice in the Clock Source menu is Video
Clock, and audio always remains resolved to
video. When the V4HD is in Audio Only mode,
this clock source setting determines the clock
source for your V4HD while it operates as an
audio interface. If no digital audio devices
are connected, set this to Internal. The other
settings are for digital transfers (via AES/EBU
or optical) or external synchronization to
other systems.
This menu lets you choose what you will
hear from the headphone jack.
The V4HD has a built-in 32-channel, 16-bus
monitor mixer called CueMix. This option
automatically ensures that live audio input
patched through CueMix remains in sync
with the V4HD's video output. For example, if
there is video conversion delay, CueMix will
also be delayed to match it.
MOTU Audio Setup appears in the dock when you launch it. If the Launch MOTU Audio Setup when hardware becomes
available option is checked (as shown above), the icon appears as soon as you switch on your V4HD interface. If you click
and hold on the dock icon (instead of clicking it) or control-click, you can directly access settings, as shown to the left.
Click the tabs to access general
MOTU interface settings or
settings specific to the V4HD (or
other connected interface, such as
the Traveler, as shown here.)
This button opens another dialog
that lets you assign your own
customized names to each V4HD
input and output. For example, if
you have a camera plugged into
inputs 1-2, you could name it
Camera Input. Your customized
names then appear in your host
audio application (if it supports
Core Audio input naming).
Choose the global sample rate
for the system here.
Specifies the stereo input and
output pair when the V4HD is
chosen for Mac OS X audio I/O.
These menus let you individually
enable or disable the V4HD's eight
8-channel audio input and output
banks. Disabling unused banks
helps conserve FireWire bus
bandwidth. For details, see "V4HD
tab Settings" on page 73.
Engages sample rate conversion
on the digital input or output bank
that you choose. See "Sample rate
conversion" on page 31.
Adds delay during playback from
Final Cut so you can align audio
with connected monitors that
have inherent video delay.
Lets you choose the audio bank
you wish to see on the bank of
front panel programmable meters.
Word clock output can either
match the current V4HD system
clock (up to 192kHz) or you can
force it to output the correspond-
ing 1x rate (either 44.1 or 48kHz).
