Composition of the parts: (Refer to the block diagram, Fig. 1)

POWER (power supply), JACK, MAIN, panel, motor (turntable), CD unit, LCD unit

Outline of the parts: (Refer to the block diagram, Fig. 1)

1.  POWER (power supply) (Fig. 9) 
     SW power supply with multiple correspondence from 100 to 240 V 
     AC inlet and fuse differ according to the destination (the constants are used in common). 
     Output of +20 V, +15 V, +7 V, +5 V, +3.3 V, -15 V 

Power supply for +20 V motor 
Power supply for +15 V analog operation amplifier 
Power supply for -15 V analog operation amplifier, power supply for LCD 
Power supply for +7 V CD unit motor 
+5 V system power supply 
+3.3 V system power supply 
+1.8 V system power supply (generated at the MAIN circuit board) 

2.  JACK 
     Composed of I/O JACK, SW, turntable drive circuit, analog circuit, etc. 

Headphone JACK: 6.3 mm specification, stereo, 20 mW (at the time of a 32 ohm load) 
Headphone volume: Variable 
LINE OUT: RCA pin type, L/R ch 
Digital output: COAXIAL 
Control: Used with connection of stereo MINI, DZ, or MZ 
Mode switching switch: Turntable mode (scratching is possible, turntable speed) 
                                      CD mode (scratching is not possible, the turntable does not turn) 
Brake: The brake at the time of turntable mode becomes variable. 

3.  MAIN 
     System control is performed. 
     Composed of the three microcomputers UI, SC, and MD. 

UI microcomputer: Control of the main panel 
SC microcomputer: Mainly control of sound processing, LCD display, audio output 
MD microcomputer: Mainly control of data reading, CD and SD data reading 

4.  Panel 
     Composed of switches, LEDs, adjustment controls, etc. 

Panel switches, LED control, volume control 
A/D method by resistance division, divided into 10 steps 

5.  Motor 
     This is the turntable motor circuit board. 
     It is composed of the motor common with SL1200. 
6.  CD unit 
     CD drive unit for CAR, with antivibration construction, max. 4x speed. 
     The MAIN circuit board uses an ATAPI connection. 
7.  LCD unit 
     This is a display LCD unit with 128 x 128 full dots and blue mode. 

UI microcomputer 
    •  Panel control 

SW10 to 40: SW input 

CD/SD: CD/SD switching input 
REV: Reverse switch input 
PCON: Pitch control switch input 
CP0, 1, CPLED, CPDATA, CPCLK: LED control
