1-11. 2TR IN/OUT (DIO) test
Contents: Use the DSP SIO and check 2TR OUT
DIGITAL → 2TR IN DIGITAL.
Preparation: Connect the 2TR IN DIGITAL to the 2TR
OUT DIGITAL of the unit with a cable.
Example of execution screen
1-12. ADAT test
Contents: Use the ATSC2 and check ADAT OUT →
ADAT IN.
Preparation: Connect the ADAT IN to the ADAT OUT
of the unit with a cable.
Example of execution screen
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.

1-6. MIDI test
Contents: Send/Receive the character string
“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.
