D6207A – Dolby E/AC3 Decoder Module

The D6207A is a DolbyE/AC3 decoder with SRC designed for broadcast use. It takes a Dolby encoded signal and breaks it down into it’s discrete channels, which are presented at it’s output as AES signal streams. It also extracts the Metadata embedded within the input signal and presents this on the output termination.

Please note the following:

  • The D6207A card accepts any AES signal at it’s input.
  • The signal may be Dolby E or AC3 encoded or PCM.
  • If the signal is Dolby E the card will output the decoded AES pairs as (L,R) (C,LFE) (Ls,Rs) (SAP, if present) (Lo,Ro or Lt,Rt, depending on selection) and Metadata.
  • If the signal is AC3 the card will output the decoded AES pairs as (L,R) (C,LFE) (Ls,Rs) (Lo,Ro or Lt,Rt, depending on selection). AC3 does not contain Metadata.
  • If the input is PCM the D6207A will provide an output on (L,R) and (Lo, Ro/Lt, Rt) as well as on the input loop all other outputs will be muted.

The D6207A supports audio sampling frequencies from 32kHz to 48 kHz.
