amplified, now the audio signal is divided into two, one is outputted to earphone
jack directly, the other is inputted into
class D
audio power amplifier
R2A15112
to be amplified and then outputted to speakers.

、
PC/YPbPr
signal flow
After processed by impedance matching,
PC/YPbPr
video signal is inputted
into main chip
MSD209
to be processed by modules of “
A/D
transform, digital
video processing and
OSD
addition”, then
LVDS
signal is outputted to drive
LCD
panel.
PC/YPbPr
audio signal is processed by circuits of “voltage divided,
impedance matching and
AC
coupling”, then inputted into main chip
MSD209
directly
for acoustic effect processing and volume control, afterwards the audio signal is
inputted into left and right sound tracks of earphone amplifier
BH3547F
directly to be
amplified, now the audio signal is divided into two, one is outputted to earphone jack
directly, the other is inputted into
class D
audio power amplifier
R2A15112
to be
amplified and then outputted to speakers.

、
HDMI
signal flow
HDMI
video signal is inputted into main chip
MSD209
to be processed by
modules of “digital video processing and
OSD
addition”, then
LVDS
signal is
outputted to drive
LCD
panel.
HDMI
audio signal is decoded into
Dolby AC-3
signal or
MPEG
multi-sound-
track digital audio signal by inner decoder of main chip
MSD209
, then one is
outputted through
SPDIF
directly; after the process of “sub-transform and
DAC
”,
the other is outputted as analog audio signal, the analog audio signal is inputted into
the rear part of main chip
MSD209
for acoustic effect processing and volume control,
then inputted into left and right sound tracks of earphone amplifier
BH3547F
respectively to be amplified, now the audio signal is divided into two, one is outputted
to earphone jack directly, the other is inputted into
class D
audio power amplifier
R2A15112
to
be amplified and then outputted to speakers.
