| This page aims to track the wiring of various cables within the breakout.

| | |
| === Mux Connection Leads ===
| |
| | |
| These are all made up using 8-core screened lead. The screen is connected to ground in all the leads, and carries no signal because all the audio is balanced. There will be a total of two Group 1 cables, two group 2 cables and two output cables needed, one of each for the top (Net) and bottom (Stream) audio muxes. The two right-hand side connectors (seen from the back of the mux) are unused because the system is mono.
