New Media used Red or Black RCAs for both video and audio, messy. RCA-R and RCA-B pattern is changed when the AUDIO_IN connectors start.
NMG seems to have used 88" of Belden 9221-010 75 ohm mini-coax, there are 11 RCA jacks, so 8" long conductor to each plug.
To me, mini-coax is overkill for audio. Looks like all grounds are brought out and then folded back over the center conductors, then a ferrule is crimped over the exposed grounds. Then the metalized hood is fastened over the ferrule.
The schematic shows the grounds connecting to DB26 pins. I'd rather put crimp-on pins onto the ground wires and connect to the DB26. A similar scheme was used on the Future Domain MCS-600, where all grounds were tied to one pin. More noise.
