output dual-track (stereo) analog audio signal. via MSD209 pre-amplifying, sound processing and
volumn control, the signal is sent into earphone amplifier BH3547 to be amplified, then output two ways ;
one way is sent to earphone jack directly, the other is inputted into class-D audio power amplifier
R2A15112FP to be amplified and then outputted to speakers.
3. AV input signal flow
AV video signal is inputted into main chip MSD209 directly and processed by modules of “VIDEO
DECODER, DEINTERLACE, VIDEO PROCESS and SCALER”, then LVDS signal is outputted to drive
LCD panel.
AV audio signal is processed by circuits of “voltage divided, impedance matching and
alternating-current coupling”, then inputted into main chip MSD209 directly for acoustic process and
volume control, then inputted into earphone amplifier BH3547F to be amplified, now the audio signal is
divided into two ways, one is outputted to earphone jack directly, the other is inputted into class-D
audio power amplifier R2A15112FP to be amplified and then outputted to speakers.
4. D-SUB/YPbPr signal flow
D-SUB, YPbPr video signal inputted into main chip MSD209 to be processed by modules of “A/D
transform, video decode, deinterlace, video process and scaler”, then LVDS signal is outputted to drive
LCD panel.
D-SUB, YPbPr audio signal is processed by circuits of “voltage divided, impedance matching and
alternating-current coupling”, then inputted into main chip MSD209 directly for acoustic process and
volume control, afterwards the audio signal is inputted into earphone amplifier BH3547F directly to be
amplified, now the audio signal is divided into two ways, one is outputted to earphone jack directly, the
other is inputted into class-D audio power amplifier R2A15112FP to be amplified and then outputted to
speakers.
5. HDMI signal flow
HDMI video signal inputted into main chip MSD209 to be processed by modules of “video decode,
video process and scaler”, then LVDS signal is outputted to drive LCD panel.
HDMI audio signal is inputted into main chip MSD209 directly for sound process, pre-amplify,
acoustic process and volume control, then the audio signal is inputted into earphone amplifier BH3547F
directly to be amplified, now the audio signal is divided into two ways, one is outputted to earphone jack
directly, the other is inputted into class-D audio power amplifier R2A15112FP to be amplified and then
outputted to speakers.
6. AV output signal flow
The present video signal is outputted after processed by MSD209 modules of decoding circuit and
peripheral video amplifying circuit. The present audio signal is processed by MSD209 modules of
pre-amplification, acoustic effect processing and volume control, then sent to operational amplifier
amplify and output.
7.
SPDIF signal flow
The present audio signal is outputted after processed by MSD209 modules of acoustic effect
processing, volume control and digital sound decode.
