Studer introduces Dolby E decoding option
Sep 21, 2006 12:59 PM
The Studer D21m I/O system, used on the Studer Vista and OnAir 3000 digital consoles, has been further enhanced by an optional I/O card for signals encoded with Dolby E. Studer is one of the first console manufacturers to offer such an expansion. A single optional I/O card accepts any AES/EBU stream containing signals encoded with Dolby E or Dolby Digital, decodes the stream within the input stage and then provides up to two sets of eight channels to the console.
Dolby E is a professional audio coding technology developed to assist the conversion of two-channel broadcast and other facilities to multichannel audio by providing eight audio channels in the same space normally used for two. Among other benefits, audio encoded with Dolby E can be edited, decoded and re-encoded many times without audible degradation.
One D21m I/O frame can take up to 12 of the new I/O cards in a 3U rack space, and each card may contain up to two decoders, making it possible to decode up to 24 Dolby E streams in just 3U of rack space. Dolby Digital or Dolby E encoded signals may be directly connected to the card’s front panel or patched via the console’s internal software patch window. Used in combination with Studer’s D21m SDI de-embedder card, it is possible to decode Dolby E signals originally contained within an SDI stream.
The dual Dolby Digital and Dolby E decoder card also features an automatic switch to a second AES/EBU PCM input in case there is no Dolby E or Dolby Digital encoded signal detected on the main input.

Vista series and OnAir 3000 consoles from Studer gain new efficiencies in terms of both space and function when fitted with the new Dolby E card.
