5.5 Audio Output panel
This panel provides additional audio processing for the eight audio channels embedded in the 3G/HD/SD output:
•
audio channel shuffling
•
level adjustment
•
mixing
•
audio embedding mode.
5.5.1 CH 1-2, CH 3-4, … CH 7-8 tabs
Each of these tabs provides all necessary controls for the
output mixers. The example shown is for the Embedded
Output, CH 1-2, but all panels have the same controls.
