The Studer D21m I/O system, used on the Studer Vista and OnAir 3000 ranges of digital consoles, has been further enhanced by an optional I/O card for signals encoded with Dolby E.
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. Audio encoded with Dolby E can be edited, decoded and re-encoded many times without audible degradation.
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.
One D21m I/O frame can accept up to 12 of these cards in a 3U rackspace, and each card may contain up to two decoders, making it possible to decode up to 24 Dolby E streams in a 3U rackspace. 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.
