TOP PREVIOUS NEXT 2 Location of ControlsTOP PREVIOUS NEXT TOP PREVIOUS NEXT 3 To Supply Power SourceTOP PREVIOUS NEXT This unit SU-C909U is designed to operate on power supplied from the Power Amplifier SE-A909S. When operating the unit SU-C909U alone for testing and servicing, without having power supplied from the Power Amplifier SE-A909S, use the following method. 3.1 Power Supply to Main Circuit 3.2 Operation Check TOP PREVIOUS NEXT 3.1 Power Supply to Main CircuitTOP PREVIOUS NEXT 1. Apply 10 V AC power to the section between the point TP1 and the point TP2 . Shown in Fig.1 2. Connect the DC+12 V to+15 V (more than 0.1 A) to the point TP5 , and the GND terminal to the point TP4 using the DC power supply. Shown in Fig.1 3. Connect the DC -12 V to -15 V (more than 0.1 A) to the point TP3 , and the GND terminal to the point TP4 using the DC power supply. Shown in Fig.1 TOP PREVIOUS NEXT 3.2 Operation CheckTOP PREVIOUS NEXT 1. Input a signal (1 kHz, 100 mV) to the each line-in terminal.2. Connect the oscilloscope or the speaker with the built-in amplifier to the PRE OUT terminals and check if the signals are outputting from this unit.Fig.1 TOP PREVIOUS NEXT 4 Operation Checks and Component Replacement/ProceduresTOP PREVIOUS NEXT TOP PREVIOUS NEXT 5 Type Illustration of ICs, Transistors and DiodesTOP PREVIOUS NEXT TOP PREVIOUS NEXT 6 Schematic DiagramTOP PREVIOUS NEXT 6.1 Schematic Diagram Notes 6.2 Schematic Diagram TOP PREVIOUS NEXT 6.1 Schematic Diagram NotesTOP PREVIOUS NEXT G This schematic diagram may be modified at any time with the development of new technology.
