channels. However, if the clip doesn’t contain an even number of channels, a channel with silence is created and
paired with the odd-numbered channel when the clip is added to a sequence.
• Mono As Stereo Maps the source audio channels so they are placed on separate stereo audio tracks when a clip is
added to a sequence. Adobe Premiere Pro duplicates the audio from mono source channels and places it in the left
and right channels of the stereo tracks. You can apply the Mono As Stereo format to clips containing any number
of audio channels.
• 5.1 Maps the source audio channels so that one or more groups of six channels are placed into separate 5.1
surround audio channels when the clip is added to the Timeline panel. If the number of source channels isn’t a
multiple of six, Adobe Premiere Pro creates a 5.1 surround audio track with silence on one or more channels when
the clip is added to the Timeline panel.
Enable Enables or disables an audio source channel. When you add a clip to a sequence, only the enabled channels
are added to the Timeline panel. Disabling a source channel also prevents you from swapping its output channel
with another source channel.
Source Channel Lists the original channels of the clip’s audio.
Track Displays the order of the sequence audio track where each channel will be placed.
Note: Under Track, the numbers don’t correlate with the actual audio track numbers.
Channel Displays the channel type and speaker location that the source channel will be mapped to.
Playback button and slider Lets you preview the audio of the selected source channel. You can preview a source
channel whether it’s enabled or not. The playback button and slider is unavailable if you’re applying the Source
Channel Mappings command to multiple master clips.
You should map source audio channels before adding a clip to a sequence. If you apply the Source Channel
Mappings command to a clip after it has been added to a sequence, you can swap only the output tracks and
channels between source channels. The Track Format and Enable controls are unavailable, preventing the master
clip’s overall configuration from becoming out of sync with instances of the master clip already in a sequence.
