Advanced Tab – Additional Audio Channels
When Secondary Audio is set to Enabled, or Additional Audio Channels are enabled, the
following changes take place:
•
Additional sets of controls are displayed in the Encoder Advanced Tab, corresponding to
each of the enabled audio channels. Each set operates independently as described in the
previous section.
•
If Secondary Audio is set to Enabled, no Advanced Audio controls are displayed in the
Advanced Tab for Encoder 2.
The example below illustrates the Advanced Audio controls when one additional audio is
enabled. In this example, Audio Channel 1 is set to MPEG-1 Layer II, from the analog input,
and Audio Channel 2 is set to Dolby Passthrough.
