This tests audio signals input from
MIC IN
for the
GUITAR/MIC
jack.
fig.test15.eps
1.
Set the
GUITAR/MIC
switch to
MIC
.
2.
Connect the UA-1G connected to the computer to the
GUITAR/MIC
jack
(MONO).
* If the UA-1G is not available, input the following signals to the
GUITAR/MIC
jack (MONO).
1-kHz sine wave at 20 mVpp
3.
Play back the
MI073_02_MIC.wav
on the computer.
4.
Connect the oscilloscope to the
MAIN OUTPUT (BALANCE)
jack and
display the waveform.
MAIN OUTPUT L (Tip): 1-kHz ±50 Hz sine wave at 8.5 ±3.0 Vpp
MAIN OUTPUT R (Tip): 1-kHz ±50 Hz sine wave at 8.5 ±3.0 Vpp
If no problems are found, press
to advance to the next test item.
16. GUITAR IN
This tests audio signals input from
GUITAR IN
for the
GUITAR/MIC
jack.
fig.test16.eps
* If the UA-1G is not available, input the following signals to the
GUITAR/MIC
jack.
1-kHz sine wave at 500 mVpp
1.
Set the
GUITAR/MIC
switch to
GUITAR (Hi-Z)
.
2.
Play back the
MI073_03_GTR.wav
on the computer.
3.
Connect the oscilloscope to the
MAIN OUTPUT (BALANCE)
jack and
display the waveform.
MAIN OUTPUT L (Tip): 1-kHz ±50 Hz sine wave at 8.5 ±3.0 Vpp
MAIN OUTPUT R (Tip): 1-kHz ±50 Hz sine wave at 8.5 ±3.0 Vpp
4.
If no problems are found, detach the UA-1G from the
MIC/GUITAR
jack.
Execution automatically advances to the next test item.
17. USB AUDIO
This verifies the operation of the
USB
function jack.
fig.test17.eps
1.
Using the USB cable, connect the unit to the computer.
2.
Play back the
MI073_04_USB.wav
on the computer.
3.
Adjust the volume level of the playback tool to maximum.
4.
Connect the oscilloscope to the
MAIN OUTPUT
jack and display the
waveform.
MAIN OUTPUT L (Tip): 1-kHz ±50 Hz sine wave at 8.5 ±2.0 Vpp
MAIN OUTPUT R (Tip): 2-kHz ±50 Hz sine wave at 8.5 ±2.0 Vpp
5.
Detach the USB cable.
If no problem is found, press
to advance to the next test item.
18. D-BEAM ADJUST
This adjusts the D BEAM controller.
fig.test18-1.eps
Set the sensitivity for the position at 5 cm above the D BEAM controller.
1.
When
Low (5cm)
appears on the LCD screen, cover the D BEAM
controller with your hand at a distance of 5 centimeters and press
ENTER
.
* If adjustment is not within the correct range, the message
RangeErr
appears
and execution does not advance to the next.
fig.test18-2.eps
Next, set the sensitivity for the position at 40 cm above the D BEAM
controller.
2.
When
Hi (40cm)
appears on the LCD screen, cover the D BEAM
controller with your hand at a distance of 40 centimeters and press
ENTER
.
* If adjustment is not within the correct range, the message
RangeErr
appears
and execution does not advance to the next.
When adjustment ends, execution automatically advances to the next test
item.
