So the video guys I'm working with just dumped $1200+ to run Cat5 to connect our Gym to the Auditorium so they can do camera shoots in both locations and just use our booth to mix from each location. They are using Broadcast (NTSC) cameras. Here's the rub. They are using Intelix baluns for the Cat5, and they purchased units that have one video (rated at 75 ohms) and 2 audio (rated 600 ohms). They are trying to send the preview video over the audio feed. Since the audio ones are rated at a different level, will they be able to send video over the other lines? Right now the preview isn't working and I hve the nutty feeling the spec'ed the wrong balun for. Thoughts?
