MIC/LINE INPUT5 ->DM circuit board ->DIGITAL STEREO
OUT L
MIC/LINE INPUT6 ->DM circuit board ->DIGITAL STEREO
OUT R
The word clock of this unit is Internal 48KHz.
(2) Execution method in the normal state
When proper operation is confirmed, press [KNOB-8]. The screen
returns to the execution select screen and "O" is displayed in the
check item space.
18:AD58DA14
NG OK
(3) Execution method in the faulty state
If checking is terminated before the end due to a faulty condition,
press [KNOB-7]. The screen returns to the execution select
screen and "X" is displayed in the check item space.
