  • Component video and/or digital audio signals sent over twisted pair wiring
  • Extended transmission distance
  • Eliminates ground loops that cause interference

Essential Info

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. Now you can take maximum advantage of this existing wiring by adding baluns to each end. This small transformer converts 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 these signals from room to room. This Component Video/Digital Audio Balun is designed for use with HDTV component video and/or digital audio equipment, sending component video and digital audio transmission up to 1000 feet. The Component Video/Digital Audio Balun is designed to work in pairs, but each is sold separately. A Coaxial RCA S/PDIF cable is required for digital audio signal transmission and is sold separately.

  • More Info

    Ideal for such devices as DVD players, satellite receivers, plasma displays, projectors, monitors, amplifiers, switchers, and other equipment supporting HDTV component video and/or digital audio, the Component Video/Digital Audio Balun allows one component video (YPbPr or RGB) signal and one digital audio signal to be transmitted via cost-effective unshielded twisted pair (UTP) cable in a point-to-point configuration. Used in pairs, the Component-Digital Balun supports 480i/p, 720p and 1080i/p video formats for hi-definition (HDTV) video applications.

    Because they contain isolation transformers and utilize twisted cabling, baluns eliminate the ground loops that cause background hum and rolling interference. Baluns also extend transmission distances, passively transmitting audio and video signals up to 2500 feet. In addition to this Component Video/Digital Audio Balun, a wide variety of audio and video baluns are available and are sold separately.

    Great product. Saved me a lot of trouble. Could not tell a difference when I used these with cat 5 cable or connected my cable box streight into the back of the tv.
    DEVAN -- cumming, IA   1/18/2007
    I am very happy with the ability to transmit HDTV video. I am still trying to find a solution to transmit the audio. My television does not have a digital audio input.

    BRIAN -- longmont, CO   4/22/2006
    Balun works very well. I have high def. C-band television and digital audio going through these baluns for about 75 feet, even near some 120v electrical wiring, and the picture and sound is perfect.
    JAMES -- apex, NC   3/8/2006
