The C4dio allows the six-slot F6 Modular I/O Frame to be configured as a 24x24 I/O device when six C4dio cards are installed. Each XLR connector on the C4dio carries a pair of digital channels, as per the AES3 specification, providing high channel count I/O in a minimal amount of space.
Optional sample rate converters can be turned on per input pair from within the Pro64 Network Manager software to allow devices with digital outputs, but without Word Clock connections, such as CD and DVD players to be used as input sources.
The C4dio can be clocked by the distributed Pro64 network clock, an AES3 digital signal connected to XLR input 1/2, or an external Word Clock signal connected to the BNC connector. The system clock can be output locally to other devices via the BNC Word Clock connector, and is also embedded in the AES3 outputs.
