Specifying your audio output settings
2 Click Audio Output.
¦NoteThe available MXO2 audio outputs depend on your MXO2 hardware.
3 Under Audio Mapping, select or clear the Enable audio mapping option.
If this option is cleared, your application’s audio track outputs will be routed
to the corresponding MXO2 audio outputs by default. For example, when
you output audio tracks as Pair 1/2 from your application, the audio will be
routed to the corresponding 1/2 MXO2 audio outputs.
4 If you selected the Enable audio mapping option, for each of the MXO2
outputs, select the desired audio pair from your application.
¦NoteIf you enable playback of Matrox 4VANC AFD or Matrox 4VANC
closed captioning, audio track 15 or 16 will be muted and won’t be available
for audio playback (see “Matrox 4VANC capture and playback” on page 68).
5 Under Miscellaneous, select the Number of HDMI channels that you
want to output from MXO2’s HDMI output. This option is especially useful
for HDMI monitors that don’t accept more than two audio channels. If you
choose to output two audio channels, MXO2 will output the audio pair
mapped to
HDMI 1/2.
6 Select Attenuate analog audio by 4dB to decrease the level of the audio
that is output from the MXO2 analog outputs by 4dB.
