Topic: A/B switch (Read 631 times) previous topic - next topic


I want to be able to use a Maxim or ADI crosspoint switch to switch between to two rf modulated tv signals.

Basically, take the channel 3 output from cable box "a" or cable box "b" and switch that coax to a tv. Each room only has one coax ran to it and would like to use a crosspoint switch. Do what a manual A/B switch box does, the cheap ones they sell at Radio Shack or hardware store.

Does anyone have background using a crosspoint switch. I'm confused on whether these require a composite input or will they be ok to use modulated output from a cable box.

The code is not a problem, just the physical switching is what I'm looking for input on.
