1-13. WORD CLOCK test
Contents:
WORD CLOCK OUT
→
IN is counted by
PLLP2 and automatically checked (Fs =
44.1/48/88.2/96 kHz).
For the PLL LOCK check, Read the
UNLOCK signal and check when the clock
is stable after the FS change (after about
200 ms).
To confirm the UnLock, disconnect the
cable connected to WORD CLOCK IN and
check.
Preparation: Connect the IN to the WORD CLOCK OUT
of the unit with the BNC cable.
Example of execution screen
1-21. LCD test
Contents:
Display the entire LCD screen in black and
white alternatively and visually check.
Example of execution screen
Check if the entire screen is displayed in black and white
respectively.
When the entire screen is displayed in black, check for
any dot flaws.
Check if the screen contrast changes when the contrast
volume is changed.
If the above is confirmed, press the [DEC] key and
select OK/NG.

or NG
1-6. MIDI test
Contents:
Send/Receive the character str ing
“SCI2:TEST¥n” (¥n = 0Ah) from/to MIDI
OUT
→
MIDI IN at 31.25 Kbps and check
that the sent and received strings are
identical.
Preparation: Connect the MIDI IN connector to the MIDI
OUT of the unit with a MIDI cable.

1-11. 2TR IN/OUT (DIO) test
Contents:
Use the DSP SIO and check 2TR OUT
DIGITAL 1, 2
→
2TR IN DIGITAL 1, 2.
Preparation: Connect the 2TR IN DIGITAL 1,2 to the 2TR
OUT DIGITAL 1, 2 of the unit respectively.
