Dolby® metadata
The Dolby Laboratories, Inc. have introduced the “data about the audio data“, the Dolby metadata which are intended to travel along with the multi channel bit stream from acquisition (point of audio recording) to delivery (Dolby Digital decoder at home (either part of the TV / Set Top Box or the home theater system). Those metadata may control the home equipment in a way that the sound impression is as close as possible to what the producers intention was when mixing a movie sound track.
There is not enough room for explanation of the Dolby metadata system in a product manual like this. We recommend to those who are not familiar with this quite complex matter, to study the many publications from Dolby Inc. probably found here:
http://www.dolby.com/gb/en/professional/technology/landing.html
You can browse the Technical Library and <Search> for “Metadata”. Here you will find the
“Dolby® Metadata Guide” and other useful information regarding Dolby technologies as well.

Set the CAN ADDR rotary encoder to an address, which is not in use by an other module of a C8000 frame (for details regarding CAN addressing, see C8000 system manual).
BUS-EN = OFF will disable the bus driver circuits on power up
SW-1B = ON enables the CAN “+16” address schema to handle up to 32 modules
SW-1C = OFF not used
SW-1D = OFF not used Important Note! If the module has an unknown bus configuration, you must set BUS-EN=OFF, before
inserting the module into a C8000 frame. Otherwise you are in risk to disturb other channels of the frame. Pressing the INIT button during power up, will initialize the module parameters to factory default values.

OVERVIEW
The above example shows a C8612 (Name: “AC3 Encoder”) in a typically processing chain.
Clicking on the spanner tool within the module graphics of the C8612 will open the pages of that
module.
If you click on the switch tool you will get the page for changing Presets only.

be assigned to one or both encoders if necessary.
