When an external clock source is being used, the Device Overview for the AllFrame will display a red dot
next to the C4dio card that is the clock source.
An external clock source is indicated by a red dot.
C4dio Sample Rate Converters.
The C4dio card includes sample rate converters (SRC) that allow external devices to be connected to a
Pro64 network without clock artifacts caused by out‑of‑sync clocks. The sample rate converters operate in
pairs and are on by default when a C4dio card is installed in an AllFrame.
The Inputs to Network view contains an SRC column that shows the state of the sample rate converters;
a yellow square indicates that a sample rate converter pair is active. The on/off state of the sample rate
converters save with device presets.
When the sample rate converters are active, a C4dio card cannot be used as an AES3 clock source.
Attempting to activate AES as a clock source will result in a warning dialog box. Turn the sample rate
converters off and try again.
