You probably have a bad word clock sync connec-
tion if:
• You hear audio but it cuts in and out at regular
intervals.
• There is no audio signal at the input of the
Digital X Bus even though everything seems to
be connected properly.
• All meters are full on and you hear a very ugly
grating, grinding, static sound.
• When the record/playback device transport
is engaged, you see the sample rate indicator
fl ashing at the top of the right screen.
Troubleshooting Word Clock Problems
• Troubleshoot through the system from the mas-
ter through the slaves. Connect the fi rst two de-
vices and verify their functionality. Once they’re
up and running, add the next device, and so on.
This is the most effi cient manner to check out a
system.
• Verify connection, integrity, and quality of all
sync cables.
• Verify a consistent sample rate setting on all
connected sync devices (all set to the same
sample rate—44.1, 48k, etc.)
• Verify that the master sync source word clock
output is connected to the word clock input
of the slave, and that additional slaves also
receive word clock. Slaves can either receive
word clock directly from the master device or
daisy-chained through connected slaves. Patch
word clock out of a connected slave into the
word clock input of any other slave.
• Verify that the master device word clock status
is set to INTERNAL.
• Verify that all slave devices are set to follow
EXTERNAL word clock.
• If the system doesn’t seem to work correctly,
you might have an intermittent or broken sync
cable. Always use high-quality 75Ω BNC word
clock cables.
