15 Dolby Decoder
Input
This menu selects the audio input pair used to feed compressed data to the Dolby Audio
Decoder (option).
16 Dolby Decoder
Mode
This parameter determines the Dolby Decoder “Bitstream Detect Mode” on the Dolby
Decoder Card. In Auto mode, the Dolby Decoder decodes Dolby E, Dolby Digital, or
Dolby DigitalPlus bitstreams. If none of the above are detected, the card passes the
incoming audio as PCM.
In Dolby E mode, the Dolby Decoder only decodes Dolby E bitstreams, and mutes its
outputs if it detects anything else.
In Dolby D mode, the Dolby Decoder only decodes Dolby Digital or Dolby DigitalPlus
bitstreams, and mutes its outputs if it detects anything else.
17 Dolby Decoder
Aux Out
The Dolby Decoder outputs eight channels of decoded audio, plus an additional Aux
output which is a 2-channel (stereo) mixdown of one of the selected Dolby Programs (1-
8). This parameter determines which of the Programs is used for the Aux mixdown.
In this context, Program is not the same as a physical input channel. To Dolby, a Program
is a related set of audio channels. For example, a 5.1 audio source requires 6 channels and
is considered one Program. Consequently, there may be a varying number of Programs
available on a given Dolby E bitstream. It is possible to have up to eight Programs on a
single bitstream if eight discrete mono channels were encoded.
