Manufacturer:
System:
type of equipment:

 


 

Benefits:The multiswitches are designed for construction of large distribution IF CCTV systems;

  • Н lines of the trunk;
  • Subscriber’s lines are up to 80 meters long;
  • Two gain controllers*  for power assistance to satellite TV and a separate controller for terrestial 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 availability;
  • A possibility of power supply from a peripheral 18 V source: a recommended power supply is SA125A-1913G-S(F)

 

MSV524   5x24 multiswitch;

MSV532   5x32 multiswitch.
