16 : A/D -> D/A (MIC)
Checks the signal path from the A/D input to D/A output. (Gain is set to MIC due to Default.)
1) Connect the level meter to [OUTPUT (Blanced)] jack.
(Connect the plug to both jacks of L/MONO and R.)
2) Set the [MASTER VOLUME] control to the maximum position.
3) Press the [ENTER] button. “
L-Channel input OFF
” is shown on the LCD.
4) Connect an oscillator to the A/D INPUT [L/MONO] jack. “
ON
” is shown on the LCD.
5) Input a 1kHz, -52dBu sine wave.
6) Move the A/D INPUT [GAIN] knob to confirm that the sound volume changes.
7) Set the A/D INPUT [GAIN] knob to the maximum position.
8) Measure the output level and confirm that the measured values are within the specified range.
[OUTPUT (Balanced)]
(600
-ohms
load)
OUTPUT L/MONO (HOT/COLD): +0.9 dBu±2 dB
OUTPUT R (HOT/COLD): +0.9 dBu±2 dB
9) Set the A/D INPUT [GAIN] knob to the minimum position.
10) Measure the output level and confirm that the measured values are within the specified range.
[OUTPUT (Balanced)]
(600
-ohms
load)
OUTPUT L/MONO (HOT/COLD): -69 dBu or less
OUTPUT R (HOT/COLD): -69 dBu or less
11) Disconnect the plug. “
OFF
” is shown on the LCD.
12) Insert the mono plug for residual noise measurement (150
-ohms
resistor end) to the A/D INPUT [L/
MONO][R] jacks.
13) Set the A/D INPUT [GAIN] knob to the maximum position.
14) Measure the residual noise level and check that the measured value is within the specified range.
[OUTPUT (Balanced)]
(600
-ohms
load)
OUTPUT L/MONO (HOT/COLD): -64 dBu or less
OUTPUT R (HOT/COLD): -64 dBu or less
15) Press the [EXIT] button, and testing is finished and the display is changed to the test item selection
screen.
17 : A/D -> D/A (LINE)
Checks the signal path from the A/D input to D/A output. (Gain is set to LINE due to Default.)
1) Connect the level meter to [OUTPUT (Blanced)] jack.
(Connect the plug to both jacks of L/MONO and R.)
2) Set the [MASTER VOLUME] control to the maximum position.
3) Press the [ENTER] button. “
R-Channel input OFF
” is shown on the LCD.
4) Connect an oscillator to the A/D INPUT [R] jack. “
ON
” is shown on the LCD.
5) Input a 1kHz, -17dBu sine wave.
6) Move the A/D INPUT [GAIN] knob to confirm that the sound volume changes.
7) Set the A/D INPUT [GAIN] knob to the maximum position.
8) Measure the output level and confirm that the measured values are within the specified range.
[OUTPUT (Balanced)]
(600
-ohms
load)
OUTPUT R (HOT/COLD): +0.9 dBu±2 dB
OUTPUT L/MONO (HOT/COLD): -83 dBu or less
9) Set the A/D INPUT [GAIN] knob to the minimum position.
10) Disconnect the plug. “
OFF
” is shown on the LCD.
11) Press the [EXIT] button, and testing is finished and the display is changed to the test item selection
