Audio power amp IC Muting control IC RDS decoder Reset IC Switching regulator Serge detection Backup detection ACC detection SW 5V AVR SW IC control Dimmer control EXT. AMP control SW
Amplifier for audio signal to derive for 4channel speakers (50W maximum for each channel). Control for timing for mute. Decode for RDS signal. When detection voltage goes below 3.5V or less Reset IC output change to "L" signal. Power supply for MP3 CD mecanism unit. When backup voltage become more than 24V output is "L" (momentary power down) / When backup voltage become less than 24V output is "H". When BU voltage supplied output is "L" / When BU voltage not supplied or momentary power down is detected output is "H". When ACC voltage supplied output is "L". When base voltage is "L" Q4 is ON. Servo regulator. Servo SW. Power supply IC controller. When base voltage is "H" dimmer is ON. Control to EXE.AMP for pulse width signal. Switching regulator control SW.
