The video separator is a signal booster and splitter that is used to take video input from a single source and direct it to two video outputs for monitors using analog signals the signal boost obtained by using the vs 102 allows you to not only split the signal but to extend the distance so that you can send the signal to about 210 feet this makes public broadcasts from a single computer very feasible if you want to display the same information on many monitors at once such as in a classroom
