Noise Check How to Enter Test Mode 1. Set all volume controls at their minimum positions. 2. Connect a DC

29、 plug to the adapter jack while pressing the pedal. 3. “CHECK” (amber) lights up, and you are in Test mode. You cannot enter Test mode unless all the volume controls are at their minimum positions. You cannot enter Test mode if the minimum values of all the volume controls are not detected due to so

30、me defect or other cause. As for how to test only a specific item skipping other test items, refer to “5. How to Test a Specific Item Only” described below after contents of tests are explained. Contents of Tests 1. Check of DSP and CPU 1. Release pedal. 2. The system checks the DSP and CPU automati

31、cally. “CHECK” LED (green) lights up if no problem is found; “CHECK” (red) blinks if an error is found. 3. Check waveforms output from both OUTPUTs A and B on the oscilloscope. Input square waves (200 Hz, 1 Vp-p) into GUITAR IN from the oscillator, and check that the same square waves (200 Hz, 1 Vp-

32、p, DSP through) as shown in the figure are output. fig.test-dsp_50 500 mV/DIV, 1 mS/DIV 4. If “CHECK” LED (green) is lit, you are already in the next step of testing. *If “CHECK” LED (red) blinks, operation stops, and you cannot go to the next step.Possible causes include defect related to the DSP o

33、r CPU, and defective soldering.Remove the DC plug from the adapter jack, and turn off the power of the machine. 2. RES Volume Check(LED check included) 1. Turn the volume control from the minimum position to the middle and then to the maximum position clockwise. The “CHECK” LED changes from green to

34、 amber, and then to green. 2. When the volume control reaches the maximum position, “CHECK” (green) light up, and the MANUAL volume check starts automatically. *The maximum RES volume value and the minimum MANUAL volume value are detected at the same time.Check the RES volume with the MANUAL volume

35、control at the minimum position. 3. MANUAL Volume Check (LED check included) 1. Turn the volume control from the minimum position to the middle and then to the maximum position clockwise. The “CHECK” LED changes from green to amber, and then to green. 2. When the volume control reaches at maximum po

36、sition, “CHECK” (green) lights up, and the DEPTH volume check starts automatically. The maximum MANUAL volume value and the minimum DEPTH volume value are detected at the same time. Check MANUAL volume with the DEPTH volume control at the minimum position. 4. DEPTH Volume Check(LED check included) 1

37、. Turn the volume control from the minimum position to the middle and then to the maximum position clockwise. The “CHECK” LED changes from green to amber, and then to green. 2. When the volume control reaches the maximum position, “CHECK” (green) lights up, and the RATE volume check starts automatic

38、ally. The maximum DEPTH volume value and the minimum RATE volume value are detected at the same time. Check DEPTH volume with the RATE volume control at the minimum position. 8 July.2002 5. RATE Volume Check(LED check included) 1. Turn the volume control from the minimum position to the middle and t

39、hen to the maximum position clockwise. The “CHECK” LED changes from green to amber, and then to green. 2. When the volume control reaches the maximum position, “CHECK “ (green)lights up. 6. CODEC (DAC) Check(Check of MODE volume and jack-switch included) 1. Position MODE volume at “GATE/PAN”. 2. Che

40、ck that “CHECK” LED (amber) is lit. 3. Connect a plug to GUITAR IN. (Waves are output even if no signal is input.) 4. Check the waveforms output from both OUTPUTs A and B on the oscilloscope. Check that the output waveforms are the same square waves (200 Hz, 1 Vp-p) as those shown in the figure. fig

41、.test-dac_50 500mV/DIV, 1mS/DIV 5. To check the GUITAR IN jack-switch, remove the plug from GUITAR IN and connect it to BASS IN. 6. Check the waveforms output from both OUTPUTs A and B on the oscilloscope.Check that the output waveforms are the same square waves (400 Hz, 1 Vp-p) as those shown in th

42、e figure. fig.test-bassin_50 500 mV/DIV, 1 mS/DIV 7. To check the OUTPUT B jack-switch, remove the plug from OUTPUT B. 8. Check the waveforms output from OUTPUT A on the oscilloscope. Check that the output waveforms are the same step-like waves (1Vp-p) as those shown in the figure. fig.test-mono_50

43、500 mV/DIV, 1 mS/DIV 7. CODEC (ADC) Lch Check (MODE volume check included) 1. Set MODE volume at “STANDARD”. 2. Check that “CHECK” LED (green) is lit. 3. Input 1kHz, -20dB sine waves into BASS IN from the oscillator. 4. Check the waveforms output from both OUTPUTs A and B on the oscilloscope. Check

44、that the output waveforms are the same as those shown in the figure. fig.test-lch_50 OUTPUT A : 50mV/DIV, OUTPUT B : 500mV/ DIV, 1mS/DIV 5. Measure the output levels of both OUTPUTs A and B with a noise meter (JIS-A). Check that the output from OUTPUT A is between -22.5 dbm and -20.5 dBm, and the ou

45、tput from OUTPUT B is -100 dBm or lower. 8. CODEC (ADC) Rch Check(Check of MODE volume and battery operation included) 1. Set MODE volume at “ULTRA”. 2. Check that “CHECK” LED (amber) is lit. 3.
