The Kathrein EXR 221 single-cable multiswitch is an innovative solution for distributing digital satellite IF signals, including HDTV, as well as terrestrial signals over a single cable. This device is ideal for use in single-family homes and allows for the connection of a twin receiver or two single receivers without limiting the variety of programs. The EXR 221 is designed to operate on two free connections of a multiswitch or a twin or quad power supply system. It generates the necessary control signals and voltages from the output voltage of the receiver, enabling easy installation and use. Additionally, the multiswitch consumes no power when all receivers are turned off, making it particularly energy-efficient. The integrated SCR tuner modules allow for precise transponder selection and the assignment of participant frequencies to the receivers. The EXR 221 complies with the SCR single-cable standard according to EN 50494, ensuring high compatibility with corresponding receivers.
