15.MIC2 AUDIO
1.
Connect an oscilloscope to LINE OUT L/R.
2.
Input a 200 Hz sine wave at 15 mVp-p to the MIC2 (XLR) connector.
3.
Rotate the MIC2 [INPUT SENS] knob from MAX to MIN to MAX again,
and confirm that the change in the waveform from LINE OUT L/R is
smooth. Also confirm that no rasping or other noise appears in the
waveform.
4.
Rotate the [INPUT SENS] knob to the 4 o'clock to 5 o'clock position and
confirm that the PEAK LED starts to light up.
5.
Connect a short plug to the MIC2 (TRS) jack and confirm that the
waveform stops in the oscilloscope.
6.
Disconnect the short plug from MIC2 (TRS).
7.
Disconnect the MIC2 (XLR) connector.
8.
Connect a noise meter to LINE OUT L/R.
9.
Confirm that the residual noise in LINE OUT L/R is no more than -76
dBu (JIS-A) when the MIC2 [INPUT SENS] knob is set to MAX.
10. Press the CURSOR [->] button to advance to the next check.
16.SUB MIX
1.
Connect an oscilloscope to LINE OUT L/R.
2.
Input a 200 Hz rectangular wave at 1 mVp-p to LINE IN L/R.
3.
Confirm that the waveform from LINE OUT L/R alternately appears and
disappears at a fixed interval.
4.
Press the CURSOR [->] button to advance to the next check.
17.SUB MIX AUDIO
1.
Connect an oscilloscope to LINE OUT L/R.
2.
Input a 200 Hz rectangular wave at 1 mVp-p to LINE IN L/R.
3.
Confirm output of the waveform from LINE OUT L/R.
4.
Press the CURSOR [->] button to advance to the next check.
18.LINE ON/OFF
1.
Connect an oscilloscope to LINE OUT L/R.
2.
Input a 200 Hz rectangular wave at 1 mVp-p to LINE IN L/R.
3.

3.
Confirm output of the waveform from LINE OUT L/R.
4.
Rotate the [PHONES VOLUME] knob from MAX to MIN to MAX again,
and confirm that the change in the waveform from the PHONES jack is
smooth.
5.
Disconnect LINE IN L/R).
6.
Connect a noise meter to LINE OUT L/R.
7.
Confirm that the residual noise in LINE OUT L/R is no more than -85
dBu (JIS-A).
8.
Press the CURSOR [->] button to advance to the next check.
20.USB
1.
Use a USB cable to connect the unit's USB connector to a computer's USB
port.

1.
The CD-RW drive model name and firmware version are indicated.
The drive tray opens automatically; insert a blank CD-RW (CD-RW).
Write to the disc, and display the checksum.
If no error occurs, the CD-R/RW tray opens automatically, and the
procedure automatically advances to the next test.
23.POWER OFF
1.
Input a 200 Hz sine wave so that the PEAK LED lights up.
2.
