Radial multiswitches of MR series are dedicated for small and medium (4-70 outlets) SMATV systems with distribution of the first SAT IF and terrestrial TV signals. The multiswitches have to work inside buildings. In the case of larger systems it is necessary to use splitters and taps of SD-5XX series to extend the signal lines.
• High class device for small SMATV systems
• For distribution of satellite and terrestrial TV, FM and DAB radio
• 12 independent outputs
• Die-cast housing with high screening efficiency
• Cable loss correction
• Groups of outlets with different output levels
• High isolation between inputs and between outputs
• Possibility of using terrestrial TV preamplifier
• 4-year warranty

Details

Radial multiswitches of MR series are dedicated for small and medium (4-70 outlets) SMATV systems with distribution of the first SAT IF and terrestrial TV signals. The multiswitches have to work inside buildings. In the case of larger systems it is necessary to use splitters and taps of SD-5XX series to extend the signal lines.
The multiswitches of MR series are are intended for systems wholly or partly based on star topology in which the cables to the terminal outlets go from one multiswitch or a group of multiswitches. This solution is optimal for single-family homes and multifamily houses. In more complex systems the power supplies built into MR multiswitches can power other system components.
The MR-512 R70612 multiswitch has 5 inputs and 12 outputs - it is used for distributing SAT TV channels from one satellite and terrestrial DVB-T, DAB and FM broadcasts to 12 outlets. In the case of twin PVR receivers, one receiver has to be connected to two outlets.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit.
The input SAT signals to multiswitch systems are provided by QUATRO LNBs.
Distinguishing features
  • radial structure
  • cable loss correction
  • groups of outlets with different output levels
  • isolation between inputs better than 30 dB
  • possibility of using terrestrial TV preamplifier
  • built-in power supply
  • die-cast housing with high screening efficiency (class A)
*two transponders/multiplexes
**without power consumption by external devices (with max. load: 17 W)
Multiswitch from well known Terra company that specializes in manufacturing professional RF equipment. The device has been designed for distributing satellite signals to a number of users (SMATV systems). High manufacturing standards, stability, reliability - make Terra multiswitches leading market products. They can cooperate with all satellite platforms.
An important advantage of MR-5XX multiswitches is diversification of signal levels at different groups of outputs. It allows to compensate the differences in attenuation of various lengths of cables that have to be used in the installation - we can get similar levels in all outlets. Additionally, the multiswitches compensate cable characteristics (provide higher levels for higher frequencies).
The device is powered with 230V AC power network. All obligatory precautions for working with dangerous live voltages should be obeyed.
