: Only AES3 1/2 In can be used as a clock source.
The Clock LED lights green when the network is using an external AES3 clock source.
If the external AES3 clock is removed, stops, or becomes intermittent for any reason, the 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 Clock LED on the C4dio will return to green.
