Dolby pulse AUTO data rates :
Encoder Latency
The latency of both encoders is 303ms independent from the mode
Compensation
If the function is Off the latency is reduced to 135ms for Dolby
Digital.
Metadata Source
[Preset, Bus & Preset, External]
For both encoders, the source of the metadata can be selected
independently either from a preset, from the c8k audio bus and
from Preset (to partially overwrite metadata from bus) or via
external (RS485) connector. In case of "External"
Metadata Program
[1 … 8]
Select
If the metadata source is "Bus & Preset" or "External" you may
select one of the 8 possible programs to define the metadata for
that encoder. If the source is set to "preset" it is fixed :
Encoder 1 is using program 1 while encoder 2 is using program 2.
