A
Does level meter of the track
that is set in the THRU deflect?
No
Does the audio signal exist
in IC5203 1pin, 2pin?
[Observation point A11
Yes
Are MCK, BCK, and LRCK
B
correctly input to IC5203?
Yes
Is the audio signal properly
output from IC5203 9pin?
[Observation point A12]
Yes
Failure in IC2000 and peripheral circuit
C
No sound comes out from the OUT1-2 / MASTER terminal and OUT3-8 terminal
Supply the audio signal (-10dBV) to the INPUT terminal
Turn the INPUT LEVEL knob to max
Turn the MAIN OUT knob to max
Enter 6.1 TEST MODE PAGE 11: AUDIO TEST/MODE1
No sound comes out
D
from all output
Yes

the OUT1-2 / MASTER terminal
Failure in the OUT3-8 analog audio output circuit
-> Confirm that each IC output of the channel
which no audio is output is normal
Failure in the audio CLK peripheral circuit
No
-> Confirm IC5008 4pin output and each
CLK output of IC2000
No
Failure in IC2000 and peripheral circuit
