The Johansson 6520 is a professional 4-channel IF processor designed for SMATV and MATV headend installations. It receives four terrestrial DVB-T UHF channels and re-transmits each to a selectable output frequency, enabling precise channel allocation across a building or campus distribution network.

The 6520 operates as a standalone unit or can be combined with other Johansson 65xx series modules — such as the Super Profiler or Profiler Plus — to build a complete, scalable headend system.
