External clock source selections for a C4dio
Word Clock LEDs
The Word Clock LED on the C4dio front panel is a bi-color LED. When the network is set to use the C4dio’s
incoming Word Clock, and a valid clock is preset at the BNC jack, the LED will light green. If the external Word
Clock is removed, stops, or becomes intermittent for any reason, the Word Clock LED on the C4dio front panel will
light red. The network will switch over to use the network’s internal clock until the external clock is restored, at
which point the Word Clock LED will return to green.
