Check the Ground Link switch. - When the main power switch is turned off, there should be no continuity between the amplifiers frame and power ground. 2. Be sure that the correct cable types are used. 3. Verify that the units power supplies,

36、outputs and frame are not shorted. 4. Main power switch OFF. 5. Prepare a sine wave generator providing a 0dB 1kHz output signal, but do not turn it on yet. 6. Plug the signal generator into Channel 1s XLR-type input. 7. Connect four 4 load impedances to each output 1, 2, 3, and 4. In case you have

37、not four impedances available, just use two, connecting them to each couple of outputs, depending of the test step you are running. 8. Connect the millivoltmeter and the oscilloscope to the amplifiers channels 1 and 2. 9. Turn down all of the potentiometers. 10. Configure Mini-jumpers to set REMOTE

38、CONTROL to ON. See configuration scheme for details. 11. Connect the amplifiers mains plug to a variac outlet, and leave its output down to 0 volts.

Turn the tested units main power switch ON. 2. Increase gradually the variacs output,

40、 until reaching 230V mains voltage. While increasing, observe carefully the unit, in order to detect any malfunction (heavy vibrations on the transformer, DC voltage on the amplifier module output, etc.) 3. Check that the red neon is lit. 4. Turn on the signal generator. 5. Verify that all the SIGNA

41、L PRESENT LEDs are also lit. 6. Turn up channel ones input potentiometer. Check that it turns easily and smoothly. At its maximum position, check that Vo=14Vrms 7. The output signal monitored on OUTPUT1 should be only dependent from the channel 1s input signal. 8. Turn up channel twos input potentio

42、meter. Check that it turns easily and smoothly. At its maximum position, check that Vo=14Vrms 9. The output signal monitored on OUTPUT2 should be only dependent from the channel 2s input signal. 10. Both output signals should be in identical phase. 11. Now change the STEREO / BRIDGE channel 1 & 2 se

43、lector to BRIDGE position 12. OUTPUT1 and OUTPUT2 should now have opposite phase. 13. Channel 2s Signal Present indicating LED turns off. 14. The units gain level is now controlled only by channel ones input potentiometer. Turn it up and leave it at its maximum position. 15. Now connect the millivol

44、tmeter and oscilloscope probes to the amplifiers outputs 3 and 4. 16. Turn up channel threes input potentiometer. Check that it turns easily and smoothly. At its maximum position, check that Vo=14Vrms 17. The output signal monitored on the output should be only dependent from the channel 3s input si

45、gnal. 18. Turn up channel fours input potentiometer. Check that it turns easily and smoothly. At its maximum position, check that Vo=14Vrms 19. The output signal monitored on the output should be only dependent from the channel 4s input signal. 20. Both output signals should be in identical phase. 2

46、1. Now change the STEREO / BRIDGE cannel 3 & 4 selector to BRIDGE position. 22. OUTPUT3 and OUTPUT4 should now have opposite phase. 23. Channel 4s Signal Present indicating LED turns off. 24. The units gain level is now controlled only by channel threes input potentiometer. Turn it up and leave it a

47、t its maximum position. 25. At this point, all clip indicators should be lighting. If necessary, add a little bit of level to the input signal. 26. Set the IN1/IN1+IN2 selector to IN1+IN2, and verify that the output signal level drops 6dB on all outputs. 27. Return the switch back to IN1. 51-0191-01

48、00 EP04-06 MPA4-80R Angls.doc 3 of 4 DC OUT VERIFICATION (please proceed without loaded outputs) 1. Select a 10Hz 0dB sine wave output on the signal generator. 2. Check that the yellow DC-indicating LED lights up, together with the green S.P. LEDs. 3. Select a 25Hz 0dB sine wave output on the signal

49、 generator. 4. Check that the yellow DC-indicating LED turns off. REMOTE CONTROL VERIFICATION 1- Release all of the input circuit selection switches. . 2- Attenuation potentiometers should all be turned up to their maximum level (right). 3- Apply a 0dB 1kHz signal on channel 1 input. 4- Check the ou

50、tput signal on channel 1s output. Vo=14 Vrms. 5- Connect the tool equipped with a potentiometer to REMOTE CONTROL CH1. 6- Check the potentiometer sweep, its response curve and attenuation. 7- Repeat this procedure on the rest of inputs and outputs, and on remote controls. 8- When done, leave the REM
