MUXLAB ANALOG AUDIO BALUN

The Audio Balun allows any unbalanced analog audio signal to be trans-mitted via a single unshielded twisted pair (UTP) cable for more versatile cabling. Used in pairs, the Audio Balun eliminates costly and bulky coax cable, allowing consumer and commercial audio equipment to be connected using standard premises wiring techniques. One or two pair of baluns is required depending on whether the application is for monaural or stereo audio. The Audio Balun features screw terminals and built-in cable strain relief for ease of installation and reliable connectivity. Applications include auditoriums, arenas, schools, home theatre systems, airports, hotels, hospitals, conference rooms.
