The Dual Audio - Video Balun (MB-DAVB) that allows two Composite Video ,

two Audio to be transmitted Via Cat5/5e/6 Cable . Video can be up to

1000ft( 305m ) ,Analog Audio can be up to 3250ft(1000m),in a point-to- point

connection . it is built in surge suppressor to protect Video and Audio

equipment against damaging voltage spikes . its integrated ground loop

isolation prevents annoying "hum-bars" common noise with long distance

installations . The product is designed for classroom Video distribution,

commercial and home Audio/Video systems , hospital video training, video

conferencing , and video kiosks Boardroom systems and so on.Used in pairs,
