#REDIRECT [[Net Mux]]
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.

For some reason I can't remember what channels 2 and 4 were for, and why it's those numbers which are blank.

Channel 16 is associated with clock and puts silence on air. It has a wire link across the pins inside the D connector and no connection to the outside world.

Outputs 1 and 2 are the same signal from independent line drivers in the NetMux unit.
