Notes:
• As for the order of the tests, the names of the keys are shown one by one from the left side of the panel to the right in
the order, and therefore press the displayed key.
• Since the accuracy of keys is to be tested here, the LED does not light on even though the key with LED is pressed.
Troubleshooting:
In case of NG, check the signal passing through the CN250 of DSP circuit board.
Or the switch is individually defective.
3-9.
DIGITAL IN Test (NO. 17)
Content: Input 96kHz/48kHz digital signal to DIGITAL INPUT connector, and then checks the operation of the DIR. The
operation of DIR is checked by checking LOCK, FS and channel status.
Example of execution screen
** 17. DIGITAL IN ***
96KHz OK.
Change 48KHz [ENTER]
48KHz OK.
AES/EBU Cable Release [ENTER]
Release OK.
EXIT:[ENTER]
1 Input Fs=96 kHz AES/EBU professional formatted digital signal to DIGITAL INPUT connector in advance.
Checks the lock condition, word clock frequency and channel status automatically, and the the rusult is displayed. At this
time, 96 kHz audio data input to DIGITAL INPUT connector is output to OUTPUT 1, 2.
2 Next, input Fs=46 kHz AES/EBU professional formatted digital signal to DIGITAL INPUT connector, and then press [EN-
TER] key of the personal computer.
Checks the lock condition, word clock frequency and channel status automatically, and the the rusult is displayed. At this
time, 46 kHz audio data input to DIGITAL INPUT connector is output to OUTPUT 1, 2.
3 Next, disconnect the XLR cable from DIGITAL INPUT connector of SP2060, and then press [ENTER] key of the personal
computer.
Checks that the status is unlock.
Test no. WORD CLOCK

Error messages and troubleshooting:
• When DIGITAL IN signal can not be locked.
In case of NG, check the signal connected to CS8416 (ANA circuit board: IC601).
• When word clock frequency is out of range.
In case of NG, check the signal connected to CS8416 (ANA circuit board: IC601) and the signal connected to EXTWC2562
(132pin) of PLLP2 (DSP circuit board: IC052).
• When the channel status error is detected.
In case of NG, check the signal connected to CS8416 (ANA circuit board: IC601).
• When the input parameter is other than 48/96 kHz.
In case of NG, check the signal connected to CS8416 (ANA circuit board: IC601) and the digital audio signal connected
to DIGITAL IN connector.
Supplementary explanation:
In this mode, L channel signal of DIGITAL IN signal is output to OUTPUT 1/3/5 connectors and R channel signal of
DIGITAL IN signal is output to OUTPUT 2/4/6 connectors.
