SPECIAL FEATURES


  • ■ Cascadable unicable multi-switch for distribution of digital sat IF signals (eight satellite frequency planes; including HDTV) and terrestrial signals via one cable to up to eight receivers in a single family household
    ■ No restriction on range of channels - the entire range of channels from a satellite is transmitted
    ■ Independent horizontal/vertical, low/high band, sat position A / position B selection and transponder selection from each receiver
    ■ Horizontal/vertical/ low/high band, sat position A/position B switching and transponder selection are carried out by the multi-switch, controlled by the receiver using a special SCR unicable command set in accordance with EN 50494
    ■ For transponder selection, the multi-switch has built-in special tuner modules, known as SCRs (satellite channel routers), for conversion to the subscriber frequencies
    ■ Each receiver is allocated a fixed subscriber frequency (a twin receiver requires two subscriber frequencies)
    ■ Compliant with the SCR unicable standard EN 50494, i.e. all unicable system components that comply with this standard can be installed in a satellite installation
    ■ Reception of the terrestrial range is possible even with the satellite receiver switched off
    ■ Unicable EXR 1981 multi-switches and loop-through multi-switches, such as the EXR 2942 and EXR 2998, can be mixed in any combination. Up to eight multi-switches can be cascaded
    ■ In the satellite range an adjustable amplifier allows optimum signal distribution to the subscriber connection
    ■ For indoor installation
    ■ Unicable multi-switch for a unicable connection for eight receivers, with built-in power supply unit for the LNB supply
    ■ Low power consumption due to high-efficiency, short-circuit proof switched-mode power supply unit and power-saving concept (the unicable multi-switch is powered by the receivers connected and is switched off when the receivers are switched off)
    ■ LNB remote feeding via the “horizontal low” inputs. All other inputs are voltage-free
