The Audio Outputs tab has the following settings:
 Outputs pop-up menu: This pop-up menu allows you to specify the number of audio
outputs available on your external audio interface. This menu defaults to two output
channels for simple stereo output. Additional output channels can be added in pairs.
You can specify as many as 12 pairs of audio outputs, or 24 total outputs.
 Channel Settings boxes: Each pair of outputs has its own settings box, each with its
own set of controls. Adding pairs of outputs adds additional settings boxes.
 Channel number: This number defines which output channel the controls affect.
 Downmix pop-up menu: Commands in this menu determine the amount, in dB, by
which an output channel should be attenuated (lowered) or boosted (raised) when
audio is downmixed to stereo—either for output to video or as a QuickTime movie
or audio file, or when the downmix box in the Audio Mixer tab is checked. When
downmixing, audio output channels can be modified from +10 dB to –10 dB, or
turned off altogether. For more information about setting proper downmix levels,
see Volume III, Chapter 4, “Audio Levels, Meters, and Output Channels.”
 Stereo Grouping buttons: These buttons define whether a given pair of audio
output channels is stereo or mono. Sequence tracks assigned to stereo pairs of
outputs have pan enabled. A single downmix pop-up menu sets the downmix
level for both channels in the pair, which defaults to 0 dB. Sequence tracks
assigned to dual mono pairs of outputs have no stereo output, and the panning
slider for that track is disabled. Two downmix pop-up menus appear, one for each
channel, which default to –3 dB. For more information about how to set proper
downmix levels, see Volume III, Chapter 4, “Audio Levels, Meters, and Output
Channels.”
Note: When you move a Final Cut Pro project file to another system along with its
sequences, those sequences retain the audio output setting with which they were
originally created, regardless of the number of audio output channels available on
that system.
