Note that the C2N-DAP8 has certain automatic
modes that can change the 2-channel decoding
mode; the user interface should use the feedback
from the C2N-DAP8 to indicate the current mode.
PL2_Width,
PL2_Dimension
I
In Dolby Pro Logic II Music Mode (and only in that
mode), several options may be selected: PL2 Width,
PL2 Dimension, and Panorama.
Valid values for PL2_Width range from 0 to 7.
Valid values for PL2_Dimension range from 0 (for -3)
to 6 (for +3).
(Panorama is defined within the list of digital inputs
and outputs.)
Neo_Cgain
I
Sets the center image adjustment for DTS Neo:6
Music sources only. Valid values range from 0 (for
0.0) to 5 (for 0.5).
Extra_Delay
O
This analog signal is normally 0 and assumes a value
of 10 if Pro Logic emulation or Pro Logic II Movie
mode is active. These two modes provide an
additional 10ms of delay; if desired, Extra_Delay can
be summed into the surround delay values to display
the actual delay rather than only the added delay.
Trim_Mode
O
Indicates the index used for mode-dependent
streams.
