1. Connect 4-200 W dummy loads to 4 output connectors (P2 and P3 as shown on Fig 1)
2. Connect the Audio Signal Generator to CN2 for CH1~CH4 respectively (AP).
3. Set up the dual power supply with voltages of ±35V; current limit to 10A.
4. TURN OFF the dual power supply before connecting to On of the unit under test (UUT).
5. Connect the dual power supply to P1. as shown on Fig 1
6. Turn ON the dual power supply. The ±B supplies must be applied and removed at the
7. The Blue LED should turn ON immediately and stay ON
8. Quiescent current for the positive supply should be 100mA 10mA at +35V.
9. Quiescent current for the negative supply should be 115mA 10mA at –35V.
10. With an Oscilloscope, monitor the switching waveform at test points VS1~VS4. Adjust VR1
11. Set the signal generator to 1kHz, 20 mV
12. Connect the audio signal generator to CN2(Input of CH1,CH2,CH3,CH4)
13. Sweep the audio signal voltage from 15 mV
14. Monitor the output signals at P2/P3 with an oscilloscope. The waveform must be a non
15. Observe that a 1 V
16. Use an unbalanced-floating signal from the generator outputs.
17. Use balanced inputs taken across output terminals, P2 and P3.
18. Connect Ap frame ground to GND at terminal P1.
19. Select the AES-17 filter(pull-down menu) for all the testing except frequency response.
20. Use a signal voltage sweep range from 15 mV
21. Run Ap test programs for all subsequent tests as shown in Fig 2- Fig 7below.
