O  Indicates the type of signal currently being decoded, 
facilitating the use of mode-specific controls via 
subpages on a touchpanel.

O 
Selects the decoding mode for a two channel signal 
(PCM, analog or Dolby 2-channel), as follows: 
 Mode 2CH_DEC_Mode 
 Stereo  0 
 Dolby Pro Logic  1 
  Dolby Pro Logic II Movie  2 
  Dolby Pro Logic II Music  3 
  Dolby Pro Logic II Matrix  4 
  DTS Neo:6 Cinema  5 
  DTS Neo:6 Music  6 
Note that the C2N-DAP8RC has automatic modes 
that can change the 2-channel decoding mode, and 
that the user interface should use the feedback from 
the C2N-DAP8RC 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 10 ms 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.
