L.6 Playing out the Extracted Audio
Individual channels or channel pairs of the extracted audio can be played back either on the
internal speaker or using the headphones in the same way as other audio (see Section K.9).
Where the OTR 1001 includes an AES card, it is also possible to configure the OTR 1001 such
that all channels of the extracted audio are output through this card.
Configuration for Multi-channel Dolby Playback
Control Panel Mouse & Keyboard
To configure the OTR for Multi-channel Playback:
1. Call up the System page of the Config window and check that the AES Clock Source is set
to the analyser that is being used to process the video from which the Dolby audio is taken.
2. Set the AES Output setting on the same page to Dolby .

3. Ensure that the Dolby decoder is active on this analyser by selecting the Dolby service
associated with this analyser on the Audio Inputs page of the Config window, taking the
Edit option and making certain that the stereo pair on which the Dolby data is carried is
ticked in the Audio Service window that is displayed.

Multi-Channel Playback
Once the above configuration has been carried out, the audio that is extracted from the Dolby
data automatically becomes played out over the outputs of I/O Ports A and B.
A number of possible orderings may have been used in encoding the channels. The ordering used
is encoded within the Dolby data. The OTR 1001 uses this data to arrange that the channel use
after decoding is identical to that used prior to the channels being encoded.
The level on each channel is taken from the level data included in the Dolby metadata.
