Revision 1 2017CDC seven31Note that the number of any connector on a stagebox is unrelated to its function.Any input (or output) connector can be assigned in software to a system input (oroutput) of any type – channel input, aux send, channel insert, matrix output, etc.– anywhere in the console’s architecture. It should also be noted that the overallI/O physical connectivity provided by the system is unrelated to the CDC seven’smaximum processing capacity of 96 simultaneous input channels mixing onto48 assignable output busses. Some additional connectors will be required in allinstallations for channel or bus insert sends and returns, and for ‘B’ inputs to inputchannels. See the Software Manual for more information.Default routingsBy default, Input A of Input Channels 1 to 32 (3216 I/O rack) or 1 to 64 (6448 I/Orack) are assigned to Rack 1 Inputs 1 to 32 or 1 to 64 respectively, in numericalorder. Similarly Outputs 1 to 13 (3216 I/O rack) or 1 to 45 (6448 I/O rack) areassigned to Rack 1 Outputs 1 to 13 or 1 to 40. The LCR Master channel outputsare assigned to the three highest-numbered output connectors: 46, 47 & 48 in thecase of the 6448 I/O Rack, or 14, 15 & 16 on a 3216 I/O Rack.Any of the above default routings may be modified at will using the on-screenInput and Output Assign functions.Connector detailsAnalogue inputs – 3-pin female XLR connectors. The inputs are electronicallybalanced, and are suitable for connection of either microphones or line levelsources. Input impedance is 1.2 kohms in Mic Mode, or 10 kohms in LineMode, Mic or Line mode being selected from the assigned channel’s Input Gainpanel. The maximum input level is +40 dBu (with pad enabled). When an inputconnector is assigned as the input of a channel in Mic mode, 48 V phantom poweris available, also switched from the channel’s Input Gain panel. The connectorshould be wired as follows:Pin Connection1 Screen2 Signal ‘hot’ (phase)3 Signal ‘cold’ (antiphase)Analogue outputs – 3-pin male XLR connectors. The outputs are electronicallybalanced with an source impedance of 50 ohms. The maximum output levelis + 21 dBu. The connector should be wired as follows:Pin Connection1 Screen2 Signal ‘hot’ (phase)3 Signal ‘cold’ (antiphase)
