Distribution examples include the following: > the full bandwidths of two satellites (analogue and digital programmes of the Astra 19,2° and Eutelsat 13° East satellites) or > eight freely selectable polarisation planes. In the satellite band, the branch switches have a slope-rectified amplification/gain, so that distances of up to 100 metres can be bridged without any need for additional equipment. The slope-rectified gain system for terrestrial signals is secure for the future, and can distribute DVB-T signals effectively even in areas receiving a weak signal. Use the mains power adapter supplied to make the connection to mains power. If the GigaSwitch 9/8 G is used without a cascade matrix, it is recommended that the energy- savings switch be set to on. Please note: When using a Cascade GigaSwitch 9/8 K, the energy-savings option must be switched off! 2 Basic unit (for a maximum of 8 parties) Art.

The manufacturer accepts no liability for damage caused by inappropriate handling, or by ignoring the safety instructions. > Components should be mounted in a dry room, on a horizontal plane, consisting or flame-resistant materials. > When installing the equipment keep the electricity switched off. > Ensure the antenna installation is earthed. > Ensure the antenna installation is protected from lightning as per local regulations. > Ensure that you are in compliance with relevant European standards and VDE regulations, where applicable, with regard to electrical safety. > You must comply with national regulations pertaining to broadcast reception installations. > Never open the housing of the equipment. Any repairs necessary should only be carried out by a qualified specialist. If the following apply, disconnect the equipment from the mains power supply, and call a qualified repair person: > the unit was subject to humidity, or water has run into the unit, > in case of malfunctions, > in case of severe external damage. 3 Installation 3.1 General > We recommend a star-shaped distribution, with the distributor being located either in the attic or near the centre of the building. If you are using a cascade matrix, please note Point 3.5. > Please ensure that the levels of the satellite signals fed into the system are approximately equal. This ensures that the very good decoupling characteristics are not limited. > As cables are very sensitive to damage, you should install these as late as possible duriung the building process. If possible, lay the cables inside a protective tube or pipe. Do not bend cables too sharply! > Install the equipment while the electricity is switched off, or disconnected. 3.2 Selecting the external unit/LNCs > You may use Quatro or Dual-Output LNCs. Please note the maximum possible current strength for inputs, as per the technical data. > Quatro-Switch LNCs, Twin LNCs and Single Universal V/H LNCs are not suitable. > The current feeding the LNCs ia approx. 18V (load-dependant). 3.3 Cable > Because of the amplification provieded by the units, you can use small-calibre, easy- to-use cables in spite of the higher damping this means. > When connecting the LNCs with the multi-switch, resp. several multi-switches with each other, we recommend the use of MULTYMEDIA cable (Art. No. 0001/3014). > we recommend you use mini coaxial cable to connect the multi-switch with the antenna sockets. > To isntall longer sections of cable to connect to the antenna sockets, please use the low-damping co-axial cable CoaxSat 2150. > Damping values are specified in Point 6. > Please use crimp-type connectors wherever possible! 4 Insulation should be stripped f...
