in the

sub-menu or when using

. When not playing or capturing, the
HD Express reverts to the Default Mode setting
(“Default Mode” on page 27).
In Playback mode, the HD Express uses the
Playback Clock Source setting (“Playback Clock
Source” on page 28), and if no application is
playing back, will output black.
ONE SOURCE TO MANY OUTPUTS
The design of the HD Express allows you to choose
a video input and the HD Express 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 HD Express 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 26.
Audio I/O and monitoring
On the audio side, the HD Express 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 HD Express 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
HD Express audio outputs. Make sure that the Mac
system sound output device setting is set to the
HD Express.
If you are capturing multi-channel audio and wish
to monitor all channels on stereo headphones or
speakers, you can enable the HD Express’s
“Downmix to Output 1-2 on Capture” option
(page 31).
