The OMNITRONIC LH-120 is a passive CAT-5 extender which allows transmission of two stereo audio signals over a single network cable (UTP/CAT-5 and higher) in a point-to-point connection. Used in pairs, the extender allows four coax audio cables to be replaced by a single CAT-5 cable up to a distance of 600 meters. Its compact design and easy installation makes the extender ideal for custom commercial and home audio systems, intercom systems, rental and staging systems and AV conference systems.
