    5/8 Multiswitch: Terra MRS-508 (passive terrestrial path)


Radial multiswitches of MRS series are dedicated for small and medium-size SMATV systems (4-70 outlets) distributing SAT IF and terrestrial signals. They are suitable for indoor use only. In the case of medium-size systems the multiswitches can cooperate with splitters and taps of SS-5XX series.
The radial multiswitches are intended for distribution systems based on star topology, where one multiswitch or a group of multiswitches is connected to the outlets of the end users via individual coaxial cables. They are therefore ideal for use in single-family houses or in single multi-family buildings. However, it is possible to use the MRS multiswitches in more complex systems. Then, the built-in power supply can be used to power other system components.
The MRS-508 R70308 multiswitch has 5 inputs and 8 outputs, and can directly be used for distribution of signals from one satellite, terrestrial TV (DVB-T), and terrestrial radio (FM and DAB) to 8 outlets. In the case of twin tuner PVR receivers, each device needs signals from two outputs of the multiswitch.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.
Due to a passive terrestrial path, the signal provided by the terrestrial TV antenna has to have adequate signal level. In the case of weaker signals, an appropriate antenna preamplifier will be needed.
Other option is to use multiswitches with active terrestrial path from the Terra MSR product line.
The input SAT signals to multiswitch systems are provided by QUATRO LNBs.
