When the pedals checks are passed, the LCD will display “PASS”.
At this time, you can press and hold [START/STOP] button then press
[+] button to enter into Test 6.
Test 6: ADC Inspection
When switch to the Test 6, the LCD will display: Adc Test L
Press the [+] button, and then rotate the master volume knob can start the
ADC inspection, and you should rotating it left and right (need to reach
the MIN and MAX), and the LCD will display the ADC value real-time.
For example, if the brilliance knob rotates to the middle position, the
LCD will display the ADC value: 127
When the master volume knob was rotated to MIN and MAX (ADC
value is 000 and 127), the LCD will display: ADC-PIT
When the pitch-bend was up to MIN and MAX (ADC value is 000 and
127), the LCD will display: PASS
At this time, you can press and hold [START/STOP] button then press
[+] button to enter into Test 7.
* If the current ADC check is failed, then the test will stop at the current position
until the current error to be solved.
* Once starting the ADC inspection (when has rotated the knob), you should
finish this test before you switch to other test items.
Test 7: Audio Test Signal Inspection
When switch to the Test 7, the LCD will display:
You can press the specific key ([C4]–[C#5]), to select output specific audio
test signal, and the LCD will indicate current audio test signal. For
example:
All the audio test signals are shown as the following table:
When you press other keys, such as [C3], it will stop output the audio test
signal, the LCD will display: AU:OFF. At this time, you can check the
