Note: If you leave P2 clips at their default mono channel mapping, use them in a sequence with a 5.1 master track, and
export that sequence to P2, the exported file contains audio only in the third and fourth channels.
1 Import the clips into a P2 project containing a sequence with a 5.1 master track.
2 In the Project panel, select the clip or clips you want to map.
3 Select Clip > Audio Options > Source Channel Mappings.
4 Under Track Format, click 5.1.
5 If necessary, click the 5.1 channel icons until they map the four source channels in this way:
• Ch. 1 to Left-Front Channel.
• Ch. 2 to Right-Front Channel.
• Ch. 3 to Left-Rear Channel.
• Ch. 4 to Right-Rear Channel.
6 Click OK.
Map sequence audio channels to audio device hardware channels
You can specify the channel in a target hardware audio device for each channel in a sequence Master track. You map
channels in the Audio Output Mapping pane of the Preferences dialog box. Premiere Pro plays each sequence channel
through the hardware channel you specify. For example, your project could have a 5.1-channel sequence, but your
system hardware might support only two channels. You could specify which of the two hardware channels carries each
of the six sequence channels.
16-channel sequences, however, remain mapped to 16 output channels if the selected hardware device has fewer than
16 channels. For example, the selected device could have only two channels. You could then map only the first two
channels of a 16-channel sequence to the two hardware channels.
Note: In the Audio Output Mapping pane, you can map sequence channels to any supported hardware device installed
in your computer, not only the device currently activated. However, you see and hear the channel mapping you specify
for a device only when the device is activated. Mapping sequence audio channels to the device does not activate the device.
To activate an audio hardware device, select it in Audio Hardware preferences.
To map sequence channels for a hardware device, you first select the device in the Map Output For menu. The list
below the Map Output For menu shows the hardware channels supported by the device chosen. You then map
sequence channels to each hardware channel using channel tiles.
For example, if you choose a third-party 16-channel audio device, the list shows 16 hardware channels. If you choose
a stereo device, the list shows only two hardware channels. Tiles to the right of each channel name in the list represent
the three types of sequence channels you can map to that hardware channel: stereo, 5.1, and 16-channel.
By default, Premiere Pro selects Premiere Pro WDM Sound (Windows), or Built-In (Mac OS) as the device. However,
if your computer has a supported third-party audio device installed, it appears in the Map Output For menu. Select the
third-party device to make its supported channels appear in the list.
1 Choose Edit > Preferences > Audio Output Mapping (Windows) or Premiere Pro > Preferences > Audio Output
Mapping (Mac OS).
2 In the Preferences dialog box, from the Map Output For menu, choose the driver for the device desired. By default,
Premiere Pro selects Premiere Pro WDM Sound (Windows) or Built-In (Mac OS).
3 Drag the desired sequence channel tile into line with the desired hardware channel in the list.
4 Click OK.
