The CDC I/O 3216 is the ideal stagebox for the CDC CDC four. It is a 4U fixed configuration unit featuring 32 mic / line analogue inputs and 16 XLR analogue outputs permitting the input count to rise to 64 along with 16 outputs on stage. The stagebox is connected to the CDC four using the MegaCOMMS card allowing the console to take advantage of Cadac’s propriety low latency MegaCOMMS audio network protocol. The CDC I/O 3216 can be located up to 150 metres (492 feet) away from the console using just a pair of co-axial cables. When connected via the CDC MC Router the CDC I/O 3216 can be part of a much larger digital audio network featuring mulitple consoles and I/O units. The mic-pres can be controlled remotely from the console and the outputs can also be assigned from the console. To complete the user interface there are signal present, clip and phantom power indication plus mute indication for the outputs.
