The MR series radial multiswitches are dedicated for small and medium (4-70 sockets) installations with distribution of the intermediate SAT signal and terrestrial TV signal. Multiswitches are designed for indoor use. If you need to connect more multiswitches, use the SD-5XX series splitters and taps to divide the bus. Radial multiswitches of the MR series are dedicated to installations wholly or partly based on the star topology, in which the wires from the end sockets converge at the place of installation of the multiswitch or multiswitch group. They are therefore ideal for use in single or multi-family houses. However, it is possible to use MR multiswitches in more complex systems. Then the built-in power supply can be used to power other components used in the installation.
MR-508 R70608 has 5 inputs and 8 outputs enabling distribution of signals from one satellite, DVB-T terrestrial television and analog / DAB radio to 8 sockets. If two-head receivers are to be used in the installation, 2 multiswitch outputs should be allocated to them. The cast housing ensures high screening efficiency by preventing interference signals from penetrating inside the device.
In multiswich based installations, QUATRO converters should be used.
