TR-2P+2AU is designed for video signal transmission via twisted pair cableThe device adjusts the impedance of a 75Ω coaxial cable to the impedance of a symmetrical cable, ensuring video signal transmission up to 400m (twisted pair cable of 5 categories) and eliminates asymmetric interferenceIn the audio path, galvanic separation takes place and the impedance of the 600Ω signal is matched to the impedance of the symmetrical cable, which allows the transmission of audio signal up to 1200 meters
Two such devices are required to build a full signal transmission path
