The CDC I/O 6448 is an 11U fixed configuration stagebox featuring 64 highly acclaimed Cadac mic-amps and 48 analogue XLR outputs. The stagebox is connected to the console using Cadac’s MegaCOMMS network protocol allowing the I/O unit to be located up to 150 meters from the mixer. The CDC I/O 6448 has dual MegaCOMMS send and receive ports on the rear for redundancy. For that extra peace of mind there is also the option for adding an additional power supply to safe guard against PSU failure. The Cadac mic-pres can be controlled remotely from the console along with output assignments. To complete the user interface there is signal present, clip and phantom power indication plus mute indication for the outputs. Larger networks can be created by using the MegaCOMMS router which can currently connect up to 4 consoles with up to 8 MegaCOMMS units.
