Radial multiswitches of MSR series are dedicated for medium-size (17-70 outlets) subscriber systems with distribution of the first SAT intermediate frequency and terrestrial TV signals. The multiswitches have to work inside buildings. Larger installations will also require to employ Terra splitters and taps of SS-5XX series to split the distribution path.
Distinguishing features
  • radial topology
  • built-in cable loss correction
  • groups of outputs with different output levels
  • isolation between outputs better than 25dB
  • powering of optional terrestrial TV preamplifier
  • built-in power supply
  • LNB powered through H lines

An important advantage of MSR-9XX multiswitches is diversification of signal levels at different 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 220-240 VAC power network. All precautions for working with dangerous voltages should be observed!
The following voltages occur at inputs of the multiswitch:
  • 18 V DC at H,lo and H,Hi
  • 14 V DC at V,lo and V,Hi
  • 12 V DC at terrestrial signal input, suitable for powering an antenna preamplifier.
