Imagine the simplicity of running a CAT5 cable through your walls
instead of a full size RCA cable.(Connectors: 3RCA Female to Female)
Many new homes and office buildings already contain structured cabling systems of not only electrical and phone wiring, but also inexpensive cat 5 twisted pair cable, which is commonly used as a data line. Take maximum advantage of this existing wiring by adding baluns to each end.
These small transformers convert audio and video signals from unbalanced to balanced and vice versa, making the necessary impedance adjustments for A/V signal transmission between different wiring systems. This means that you can run your signal over inexpensive cat 5 wiring, rather than rewiring your home in order to send video and audio signals from room to room.

Ideal for such devices as DVD players, satellite receivers, Cable boxes, Video Games, plasma and LCD displays, projectors, monitors, amplifiers, switchers, and other equipment supporting audio or video signals and transmitted via cost-effective unshielded twisted pair
(UTP) cable in a point-to-point configuration.
