b From the DD+ Output drop-down list, choose the Dolby Digital Plus output
mode. If Trans is selected, it will transcode to Dolby Digital audio output. If
Pass (passthrough) is selected and the bitrate is less than 1536 kbps (48 Khz),
passthrough is performed and Dolby Digital Plus compressed out is received.
If Pass (passthrough) is selected and the bitrate is more than 1536 Kbps,
transcoding will be performed. This setting affects only the AES-3id and SDI
outputs.
Note: Dolby Digital Plus is only available on Audio 1.
Note: Ensure that the Digital Out Preference is set to Compressed for digital
passthrough. Otherwise, only decoded PCM will be available. This parameter
has no effect if the audio source is not Dolby Digital Plus.

Audio Decode drop-down list and the source audio channel (left or right)
from the Channel drop-down list for Group Slot 1 to 4. The Group Slot is the
HANC position.
