1 The unit turns to KARAOKE MODE with ou-screen lyrics display and melody sound when it play backs
VCD or DVD KARAOKE DISC.
2. IF a microphone is connected at this time, MICON recoguizes the connection and prepares the compo-
sition of external voice and internal melody.
3. The week signal of the microphone is converted to the digital signal after voice output that has passed
through PREAMP(BA3308) and AMP(KIA4558) passes through(CS5331) that is Audio ADC(Analog to
Digital convertor).
4. This digital signal enters NS that is MPEG IC and is added to the output of DVD DSP (Processor)
5. This mixed signal is output to AV JACK after passing through AUDIO DAC(CS4392).
