Note 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 (or
output) 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 overall
I/O physical connectivity provided by the system is unrelated to the CDC seven’s
maximum processing capacity of 96 simultaneous input channels mixing onto
48 assignable output busses. Some additional connectors will be required in all
installations for channel or bus insert sends and returns, and for ‘B’ inputs to input
channels. See the Software Manual for more information.
Default routings
By default, Input A of Input Channels 1 to 32 (3216 I/O rack) or 1 to 64 (6448 I/O
rack) are assigned to Rack 1 Inputs 1 to 32 or 1 to 64 respectively, in numerical
order. Similarly Outputs 1 to 13 (3216 I/O rack) or 1 to 45 (6448 I/O rack) are
assigned to Rack 1 Outputs 1 to 13 or 1 to 40. The LCR Master channel outputs
are assigned to the three highest-numbered output connectors: 46, 47 & 48 in the
case 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-screen
Input and Output Assign functions.
Connector details
Analogue inputs – 3-pin female XLR connectors. The inputs are electronically
balanced, and are suitable for connection of either microphones or line level
sources. Input impedance is 1.2 kohms in Mic Mode, or 10 kohms in Line
Mode, Mic or Line mode being selected from the assigned channel’s Input Gain
panel. The maximum input level is +40 dBu (with pad enabled). When an input
connector is assigned as the input of a channel in Mic mode, 48 V phantom power
is available, also switched from the channel’s Input Gain panel. The connector
should be wired as follows:

Analogue outputs – 3-pin male XLR connectors. The outputs are electronically
balanced with an source impedance of 50 ohms. The maximum output level
is + 21 dBu. The connector should be wired as follows:
