Switcher is applicable for classrooms, boardrooms, houses of worship, rental and staging. It is ideally suited for stand alone use or as an upstream switcher for a stand alone scaler such as the FSR MAS-3100 or a scaling switcher such as the FSR Compass, Compass S2 or Omni Navigator. The SN- 4100 could also be used to route 4 high resolution signals to a down converter such as the FSR MDC-MK1.
