Stereo audio balun allows unbalanced line level stereo analogue audio to be transmitted via Category 5 unshielded copper twisted pair (UTP) in point-to-point connection. It is designed for audio applications where primarily midrange audio frequency response is required. Used in pairs, stereo audio balun eliminates costly and bulky coaxial cable, allowing audio equipment to be connected or moved within structured cabling environment. Stereo audio balun also works in conjunction with other MuxLab products such as 500019, 500001, 500012, 500017 and 500200 for more complete cabling solution.
