26、 Main Board consists of the following features : a.TDA7468D TDA7468D (IC704) provides the basic sound processing - loudness, bass, treble, volume & mute controls and source selection - TUNER, TAPE, CD & AUX including Mic mixing for the set. Sound features such as ALC, DBB, DSC and IS are controlled

27、by the microprocessor IC on the Front Board via I2C Bus. Undesirable noise during source switching are muted off by via the software of the microprocessor IC on the Front Board. c.MIC MIXING Simple Mic mixing is provided by pin 2 of TDA7468D. During Mic mixed a 1nF capacitor is connected across this

28、 pin to ground instead of a chip connector(0R). d.HEADPHONE AMPLIFIER Headphone amplifier NJM4556AM is provided after the Sound processor to drive 32 ohm to 1kohm headphone. The TDA8947J contains a unique protection circuit that is solely based on multiple temperature measurements inside the chip. T

29、his gives maximum output power for all supply voltages and load conditions with no unnecessary audio holes . voltage and load impedance combination can be made as long as thermal boundary conditions external heatsink and ambient temperature) allow it.
