What is the maximum length for S Video cable and how do you increase the range?
There are a lot of issues that can develop when running long
lengths of cable. A safe length for S-Video is 150ft. This
length is subject to signal strength from the source unit and being
run in an area that is relatively free from interference.
If you need to increase this length, you can use a device called an S-Video Balun. The S-Video Balun is a stand alone device that transforms a single S-Video channel to and from CAT-5 twisted pair cabling. CAT-5 cable is much cheaper than S-Video and can be run up to a maximum of 500 ft.
