The HORIZON 8000 Change Over Unit is capable of making a clean switch between two inputs maintaining continuity synchronization for signals of SDI, PAL/NTSC, AES/EBU, Analogue Audio and Transmission lines of E1 to E4. It will prevent momentary malfunction of downstream equipment when cutting between two sources.

     Redundancy switching is initiated automatically upon detection of any inferior of the signal protocol registration. The unique system design feature includes the loop thru function in the event of system collapse or corrupted condition where critical matters such as elimination of single point of failure are being addressed.
