We have two 50 metre general purpose video camera multicore cables. There's a break-out box at each end of the cable, attached by multipin connectors, with:
Two video BNC connectors at each end. Intended for video and genlock signals, but could be used for split Y/C video.
Two unbalanced lines with ¼″ TS sockets at each end. Used for tally and line-view video return signals.
An intercom line. With an intercom station built into the remote end, so a headset plugs straight into it. And a multi-pin plug at the control end, to connect to the intercom base station.
Users of these cables must learn, or already know, how to properly handle cables. For storage they must be over-and-undered, or figure-eighted. They must be handled properly at all times, not just when returned to us. We will not accept mangled cables, and, if damaged, you will be charged to replace the entire cable.
