The Quartet is a 3G Ready ASI & HD/SD-SDI Switching Distribution Amplifier. It is Ideal for supporting encoder redundancy without a DTA. The Quartet features automatic or manual switching with automatic rate detection.


  •   Two Inputs: Primary input A with secondary input B used as backup.
  • Two Front Panel LEDs: Power - Green indicates powered up. Signal - Green indicates a valid signal is being passed through the system.
  • Two Selectable Modes (via external RST): When LEFT and CENTER terminals are shorted together the PRIMARY signal passes. When the RIGHT and CENTER terminals are connected the SECONDARY signal passes.When any of the previous two modes are selected the unit will not use the redundancy backup signal. When the unit is not in manual override mode it uses the secondary signal as a backup.
  • Redundancy Backup: When signals on both the primary and secondary are valid the primary signal will pass. If this signal is lossed then the secondary signal will pass. If there is no secondary and primary signal, no input passes. Once a valid signal is connected the unit will then pass that signal, however the primary input takes precedence so if both signals are again connected the primary will pass. If the primary is lossed again the unit switches to secondary. If the primary is then reconnected it will go back to passing the primary. All inputs use autorate detection.
