Default Stereo Input/Output - MOTU UltraLite-mk3 Hybrid User Manual

S/PDIF
The S/PDIF clock source setting refers to the
S/PDIF RCA input jack on the UltraLite-mk3. This
setting allows the UltraLite-mk3 to slave to another
S/PDIF device.
Use this setting whenever you are recording input
from a DAT deck or other S/PDIF device into the
UltraLite-mk3. It is not necessary in the opposite
direction (when you are transferring from the
UltraLite-mk3 to the DAT machine).
For further details about this setting, see
"Connecting and syncing S/PDIF devices" on
page 22.
SMPTE
Choose this setting to resolve the UltraLite-mk3
directly to SMPTE time code (LTC) being received
via the UltraLite-mk3's quarter-inch SMPTE input
jack. For details, see "Syncing to SMPTE time
code" on page 112and chapter 12, "MOTU SMPTE
Console" (page 109).
Built-in Audio
Choose this setting to resolve the UltraLite-mk3 to
your Mac's built-in audio. Doing so will ensure that
audio streams playing back from or recorded by
the UltraLite-mk3 will not drift apart from audio
streams simultaneously played or recorded by the
Mac's built-in mic, speakers or audio output. For
complete details, see "Resolving to other Core
audio drivers" on page 26.
Other audio devices (drivers)
The MOTU FireWire Audio Driver has the ability
to resolve to other Core Audio drivers. Doing so
will ensure that audio streams playing back from or
recorded by the UltraLite-mk3 will not drift apart
from audio streams simultaneously played or
recorded by the other devices. For complete details,
see "Resolving to other Core audio drivers" on
page 26.

Default Stereo Input/Output

In the System Preferences window, Mac OS X lets
you choose third-party hardware such as the
UltraLite-mk3 for your Mac sound input and
output. The system input and output can be used
for alert sounds and general audio I/O for
applications like iTunes, iMovie, etc.
Figure 5-2: The Mac OS X sound preferences let you use the
UltraLite-mk3 for general stereo audio input and output for your
Mac.
The Default Stereo Input and Default Stereo Output
settings in MOTU Audio Setup (Figure 5-1 on
page 34) let you specify the stereo input and output
on the UltraLite-mk3 to be used when it is chosen
as the audio I/O device in the system preferences.
