SMD technology for high reliability
Built-in mains power supply with UK plug
Optima IR DA’s are designed to easily distribute TV and radio signals in a domestic environment and pass IR commends back
to the UHF input for a Sky™ satellite receiver 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.
For best results always ensure any unused outputs are properly terminated with a 75ohm load. Use V17-007 F terminator. Multipoint domestic aerial systems may require earthing. Consult
the latest codes of practice & legislation for information.
