Quad audio balun allows up to four (4) analog line audio signals to be transmitted via unshielded twisted pair (UTP) cable in point-to-point connection. Used in pairs, quad audio balun eliminates up to four (4) coaxial cables, allowing audio-video equipment to be connected via space-efficient and cost-effective Category 5 twisted pair cable. Quad audio balun also works in conjunction with other MuxLab analog audio baluns such as the 500019.
