  • 1.  Dolby E trought Ross Ultrix

    Posted 06-18-2025 10:19

    Hello.

    I need to route a video with embeded Dolby E through a Ross Ultrix. Is this possible? If so, can I shuffle this Dolby E? Of course, the Dolby E pair always goes together and on the same pair.

    Hi Carlos,

    Yes, you can route Dolby-E through Ultrix. We recommend enabling "Audio Bypass" in the configuration for inputs with Dolby-E. When enabled, when a video source is routed to a destination, it will override the audio routing but ensures proper alignment of the Dolby metadata. 

    If "Audio Bypass" is not enabled, it is possible to shuffle the Dolby-E to a different audio pair, but there is no guarantee about placement of the metadata in this case. Also, you would not be able to breakaway the Dolby-E audio pair, as the VANC/metadata is carried with the video.

    Frame sync should always be disabled on any input carrying Dolby-E.

    Cheers,

    Alun
