  • Dual mono or single stereo audio signals sent over twisted pair wiring

  • Eliminated 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. These small transformers convert audio, video, or VGA 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. The Stereo Audio Balun provides a low-cost, versatile cabling solution for dual mono or single stereo analog audio distribution, utilizing a building's existing structured cabling system. The Stereo Audio Balun is designed to work in pairs, but each is sold separately. A cat. 5 patch cord is required for each end and is sold separately.


What's Included

  • Balun
  • Instructions
  • More Info

    Used in pairs, the Stereo Audio Balun transmits analog audio via twisted pair wiring up to 2500 feet. The Stereo Audio Balun is ideal for corporate AV, assembly halls, schools, and virtually any other situation involving structured audio distribution. Connect the RCA inputs from the audio source equipment to the balun and connect a cat. 5 patch cord to the other end.

    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 and actively transmitting VGA signals up to 550 feet. In addition to these Stereo Audio Baluns, other available baluns include Component/Composite Video Baluns w/RCA Connectors, Component/Composite Video Balun BNC, Dual Stereo Audio Baluns, High Resolution VGA Baluns, and Ultra-High Resolution VGA Baluns, all sold separately.

    They work well. I already had CAT-5 in place,and needed to run stereo audio. A perfect answer to the need.

    Have always had good service and delivery from Smarthome. Your new website makes purchasing easy, and the products are reliable.

    This is a great product! I tried many solutions to connect my computer sound card to my stereo and always had ton of noise and sorry sound. I didn't have much faith in the baluns before I bought them, but two baluns and some CAT 5 cable give me a great-sounding, noiseless connection. I only regret that I didn't get the dual stereo baluns!
