Introduction
The Composite Video, Stereo Hi-Fi Audio / IR Pass-Thru Balun (CVHFIRB) allows one composite
video, one stereo audio and one IR emitter signal to be transmitted via a single Cat5e/6 cable in
a point-to-point connection.
The Composite Video,Stereo Hi-Fi audio / IR Pass-Thru Balun works in pairs. Some of the applications
are classroom video distribution, commercial and home audio/video systems, hospital video training,
video conferencing, and video kiosks
