(16) DIGITAL I/O
(1) Outline
The DIGITAL I/O (SPDIF format and signal transmission/
reception) function is checked. Connect DIGITAL STEREO IN
and OUT on the back panel with one coaxial cable (75
Ω
) in a
loop in advance.

(17) AD14DA14 (48k)
(1) Outline
The input signal of AD1-4 is output to DA1-4 and the circuit of
the analog signal system is checked. Specifically, the following
signal passages are checked.
MIC/LINE INPUT1 ->DM circuit board ->MONITOR OUT L
MIC/LINE INPUT2 ->DM circuit board ->MONITOR OUT R
MIC/LINE INPUT3 ->DM circuit board ->STEREO/AUX OUT L
MIC/LINE INPUT4 ->DM circuit board ->STEREO/AUX OUT R
MIC/LINE INPUT1 ->DM circuit board ->PHONES L
MIC/LINE INPUT2 ->DM circuit board ->PHONES R
MIC/LINE INPUT1 ->DM circuit board ->DIGITAL STEREO
OUT L
MIC/LINE INPUT2 ->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.
