The program configuration-encoding mode of this product depends on the metadata information provided
to it. This metadata information can be de-embedded from VANC, received serially over the RS-422 DB-9
connector (i.e. from a Dolby DP570), sourced from the module's metadata processor, or automatically by
selecting a preset program configuration.
The automatic preset program configurations available include:
•
5.1+2
•
5.1
•
5.1+2x1
(5.1+1+1)
•
4x2
(2+2+2+2)
•
3x2

•
8x1
(1+1+1+1+1+1+1+1)
•

(1+1+1+1+1+1)
Mixer-B is used to route and adjust any input audio from AES or embedded source sends it to the Dolby-E
encoder. Each of the 8 outputs of Mixer-B is mapped directly to the 8 inputs of the Dolby-E encoder.
