Setting Up the AAC Audio Input

To Set Up AAC Audio
Proceed as follows to set up AAC audio:
1. From the user interface of the D9054 HD Encoder, click the Audio tab, expand
the AAC icon and click the appropriate channel icon from the sub-pages.
Note: The number of channels displayed depends on whether your encoder is
equipped with a Dual Channel Audio (DCA) card or a Multiple Channel Audio
(MCA) card. MCA cards provide six configurable audio channels, allowing you
to configure Ch 1 (Audio 1) through Ch 6 (Audio 6).
2. Select Enable AAC to enable the AAC engine. Whether you are encoding AAC
or passing through pre-encoded AAC depends on the Passthrough of AAC
setting below.
3. If relevant, select on for Passthrough of AAC; otherwise setting this to Off uses
the internal encoding engine.
Passthrough of AAC requires that AAC Encoding be enabled in the GUI.
For Passthrough of AAC you can set the Input Type to Digital or Embedded.
Note: It's possible to enable passthrough of AAC without having the AAC
option installed.
Note: The Sample Rate must be set to 48 kHz if Passthrough of AAC is enabled.
