Video Composite Audio Balun Extender Over CAT5 for Sound Bar Amplifier 1000m


The Composite Video/Stereo Hi-Fi Audio Balun that allows one Composite video, one  Stereo Hi-Fi Audio to be  transmitted  Via Cat5e/6 Cable,up to 1000ft(305m) 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,Working With MB-CA1000,the Composite/Audio can be transmitted up to 3250ft(1000m). the  Video/Audio Balun  eliminates costly and bulky coaxial  cable,allowing Video/audio equipment to be connected or moved within a structured cabling environment.
