The multiswitches are dedicated for small (4-16 outlets) and medium-size (17-70 outlets) installations distributing SAT IF and terrestrial signals. They are suitable for indoor use.
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 220-240VAC power network. All precautions for working with dangerous voltages should be observed!
At the inputs of the multiswitch there are the next operating voltages:
  • 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.
