2-10. Audio L and R 2ch Signal Block
The audio signal data for 2 channels of the MB-78 board AV decoder IC203 (L64020) is passed
through IClOlMGA, passed through the digital filter in the AU197 board IC215 (CXD8750),
converted to analog signal in the DAC, and passed through the LDF to become the line out
signal.
