  • Page 14 (B) Audio Circuit The circuit includes one AV2 audio, one PC/YPBPR audio multiplexing, one S video audio and one AV1 audio multiplexing input. HDMI has its own audio input. All audio frequency signals are input to U8 of MST9U88L, where the signals are processed with alt, undertone, balance and bass effects; after that, they go into U16 for SRS WOW processing and then drive the audio amplifier circuit TDA8932.
  • Page 15 the loudspeaker. LM833 is a low-voltage double-channel operational amplifier which is mainly characterized by low-voltage noise, 15M bandwidth, low distortion of 0.002%, 2KV static-proof design and good frequency character. The internal circuit diagram is as follows: The audio signal of this machine is output from U5 Pin 8 and input through U8 Pin 80. AV1 input AV1 video is input in a balanced way from XS3B, L18 R150 and R152 to U8 Pin 54 and Pin 56.

S-VIDEO S video signal is input from the socket XS3A, with C signal from Pin 1 and Y signal from Pin 2.
  • Page 18 The mute at the power-off status of machine is realized in this way: when the machine is turned on, C292 16V 470UF will be charged and when the machine is turned off, +12V will become 0V, C292 and C391 will discharge to open V16 and V15 so as to reduce the level of N12 Pin 5. The mute at the power-on status of this machine results from the fact that C292 and C391 capacitors cannot be rapidly and completely filled and thus the voltage at N12 Pin 5 cannot be established neither.
