8 Way Variable Gain Distribution Amplifier with IR Return Indoor – Multi-output domestic distribution amplifiers with IR return path and level control

Optima IR DA’s are designed to easily distribute TV and radio signals in a domestic enviroment and pass IR commends back to the UHF input for a Sky™ satellite reciever with an active return path. Each output has high gain for long cable runs and a level control to avoid overload. Each output also powers at 9v DC a Visionlink or similar IR “eye” at maximum 15mA with overload and short circuit protection.

  • High quality fully screened amplifiers with F connectors
  • High gain / high output, ideal for digital TV
  • Input filtered to minimise 4G-800 LTE interference
  • IR Visionlink™ compatible with Sky™ satellite recievers
  • IR powering and short-circuit protection on each individual output
  • Level control for optimum performance
  • SMD technology for high reliability
  • Built-in mains power supply with UK plug


For best results always ensure any unused outputs are properly terminated with a 75ohm load. Used V17-007 F terminator. Multipoint domestic aerial systems may require earthing. Consult the latest codes of practice & legislation for information.
