other is sent to sound power amplifier TDA7266SA (class AB) to be amplified and then drive post
speakers.
3、 AV input signal flow
AV video signal is sent into main chip MSD209GL to be processed by modules of video decoding,
reversed interlace, video processing and zoom, then LVDS signal will be outputted to drive display panel;
AV audio signal is sent into main chip MSD209GL for acoustic effect processing and volume control
after the processing of voltage division, impendence matching and AC coupling, then it is sent to
earphone amplifier BH3547F to be amplified, one is sent to earphone jack, the other is sent to sound
power amplifier TDA7266SA (class AB) to be amplified and then drive post speakers.
