Product Information：

Overview

The Composite Video/Stereo Hi-Fi Audio Balun(MB-CVHFB) that allows

one Composite video , one Stereo Hi-Fi Audio to be transmitted Via

Cat5/5e/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
