Benefits:

  • The multiswitches are designed for construction of large distribution IF CCTV systems;
  • Power supply is effected through Н lines of the trunk;
  • All components of 5-cable distribution system are mutually compatible in a constructive way and in their technical
  • Subscriber’s lines are up to 80 meters long;
  • Two gain controllers  for power assistance to satellite TV and a separate controller for terrestrial TV;
  • The multiswitches are optimized to operate with digital-to-analog  signals of terrestrial TV;
  • Reception of terrestrial TV programs is possible without a CCTV receiver being turned on;
  • Visual display of 18 V power supply;
  • A possibility of power supply from a peripheral 18 V source.
