Audio Bar Mapping vs. Dolby E Metadata Program Configuratio n
If your instrument has Option DDE installed and is decoding Dolby E audio, the bars in the Audio display are m apped as
shown in the following table. The mapping derives from the Dolby E Program Configuration detected in the metadata of the
Dolby input. If you select a Downmix Program, the two downmix level bars in the Audio display reflect that program selection.
