Which cable connects the Mainframe to the TC Icon?

The correct choice indicates that there is no specific cable designated for connecting the Mainframe to the TC Icon, which is accurate in the context of how the TC Electronic System 6000 operates. The communication and control between the Mainframe and the TC Icon are facilitated through the software and internal networking rather than a physical cable connection.

While the other options present various types of cables that are common in different audio and data applications, they do not specifically pertain to this connection in the S6000 system. For instance, a 25 pin D-sub cable is more often associated with control and audio transfer in different contexts, while a 36 pin multi-cable might serve a different piece of equipment or purpose entirely. The cross-coupled ethernet cable also refers to a network configuration that is not how the TC Icon interfaces with the Mainframe. Thus, selecting “None of the above” effectively captures the correct operational connection, emphasizing that the system relies on internal communication mechanisms rather than a direct physical connection.
