I had an insidence recently to send video from a DVD player in the control room to the side of a stage for a video projector in a small theatre.
With NO video tie lines and with 30mins to do it, I used the audio patch bay down the audio loom to the side of the stage... to my surprise it worked and with quite good quality.
I have often used L/R RCA - XLR to feed an unbalanced stereo signal down a mic cable.
Has anyone else got a similar story to tell?
I have had the same experience of running video down audio cables and audio down video cables.
The challenge is with proper shielding and cross talk.
It took me a while to figure that audio was getting into the video signal. Everytime there was audio, the video got a little noisy. Stop the audio and it went away.
Do what works.
