    The D6207A is a DolbyE/AC3 decoder with Sample Rate Conversion (SRC) designed for broadcast use. It takes a Dolby encoded signal and extracts the discrete surround sound channels and presents them as AES pairs on a T6305A rear module. It also extracts the Metadata embedded in the Dolby signal and presents this on an output terminal on the rear modulet.
    The D6207A card accepts an AES signal at its 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 card will provide an output on (L,R) and (Lo, Ro/Lt, Rt) as well as on the input loop through. All other outputs will be muted.
    The D6207A supports audio sampling frequencies from 32kHz to 48 kHz. The D6207A is housed in the openGear DFR8300 series frames.
