CONVERTER section (DN9650 only)
This
section shows the status of the configured
clock source, which can be AES50 output,
ASRC or network output. Each source has a

show that the source is enabled. The DN9650
also has the facility to stop the output clock if
the input clock fails. This condition is indicated
by the illumination of the red
STOPPED LED.
