5、s - 14 START - UP 1-check all wires and components 2-Check screws and bolts 3-Connect the jumpers for 120 Volts 4-Turn the bias all the way to 0 volts 5-Connect the unit in bypass mode 6-Connect the unit with variable transformer 7-Connect speaker cables, regular and balanced inputs 8-Apply 10V AC f

6、rom variable transformer and check the rail and driver voltages 9-If the unit is OK increase the voltage up to 120V 10-Turn off the unit and remove by pass 11-Turn on the unit and check the rails driver and offset 12-Check the sequence of relay clicking 13-Adjust the bias and offset 14-Check the pro

7、tection circuit both channels 15-Check the signal with 8 and 4 load in 16-Regular, regular mono, balanced stereo and balanced mono 17-Check noise with small speaker and RCA shorted plug 18-Put in burning bench CD/DVD-1 CD/DVD-1 FINAL TEST Class - 15 1. Before final test unit was 4 days on burn-in-be

8、nch with music. 2. Take the unit from burn-in-bench to Q.C and play it immediately. Keep the line 120V A.C. 3. Check physically and check the components. -check all capacitor and devices direction. Capacitor stand up right way i.e. check co- solder. -check any missing parts. -check all fuse sockets.

9、 -check main board tight up with screw and washer. -check any screw missing. -check balance lock working smoothly. -check all output transistors position with pad. -check main transistors position with pad. -check main transformer tight very well. 4. Adjust bias 26mV for every output devices for bot

10、h channels. Wait 7 to 8 minutes after each adjustment. Also adjust offset to 0mV. 5. Measure rail and pre-driver voltage. 6. Measure A.C voltage for bridge. 7. Measure supply voltage for relays. +15V and 15V for both channels. +12V and 12V. 8. Measure reference voltage 8.1V on both channels. 9. Meas

11、ure reference voltage for protection 78V. 10. After setting the bias, connect load and input signal. Check output signal. Check phase with input signal. 11. Measure frequency response, slew rate, gain, signal to noise ratio. 12. Check the output signal from 20Hz to 20KH with load in following combin

12、ation. Also measure the output power. Regegur-stereo Balance-stereo Regegur-mono Balance-mono 13. Check phone-jack. 14. Check protection on both channels. 15. Check noise with speaker. 16. Put the jumpers and varistor for required A.C voltage. 17. Plug unit again and check rail and pre-driver voltag
