mode when All Frames or Single Frames is selected
in the External Video sub-menu or when using
Print to Video. When not playing or capturing, the
HDX-SDI reverts to the Default Mode setting
("Default Mode" on page 35).
In Playback mode, the HDX-SDI uses the Playback
Clock Source setting ("Playback Clock Source" on
page 36), and if no application is playing back, will
output black.
ONE SOURCE TO MANY OUTPUTS
The design of the HDX-SDI allows you to choose a
video input and the HDX-SDI sends the signal to
any outputs that match the input format (HD or
SD). This allows you to simultaneously connect a
number of input devices, such as cameras, video
decks, DVD players, etc., along with a number of
output devices, such as monitors, video decks and
other destinations. Then choose the desired input
device and the HDX-SDI will feed that signal to all
matching output destinations simultaneously.

Choosing the current video source
The MOTU Video Setup software lets you choose
the current video source (input). For details, see
"Input Source" on page 34.
Audio I/O and monitoring
On the audio side, the HDX-SDI feeds audio input
to the computer and plays audio back from the
computer, so that you can easily capture and
playback audio in Final Cut Pro.
The HDX-SDI supports Final Cut Pro's Preview
feature (in the Clip Settings tab in the Capture
window). When the Preview option is checked,
incoming audio is "patched through" to the
HDX-SDI audio outputs. Make sure that the Mac
system sound output device setting is set to the
HDX-SDI.
If you are capturing multi-channel audio and wish
to monitor all channels on stereo headphones ore
speakers, you can enable the HDX-SDI's
"Downmix to Output 1-2 on Capture" option
(page 41).
