When to try changing the decode mode

When the decode mode is set to the default AUTO/PCM setting and a DVD recorded in Dolby Digital Surround or DTS Digital Surround is played, the internal decoder will be automatically se- lected before audio playback begins. Depending on the disc re- corded in DTS Digital Surround, this may result in a brief loss of audio after playback starts. This is due to lost audio signals that were inputted during internal decoder selection.

In these instances, lost audio can be prevented by manually select- ing “DTS” beforehand.

However, please note that when the decode mode is set to DTS, you will be unable to playback audio from discs recorded in a mode other than the DTS Digital Surround.

After changing the decode mode and playing back a disc, return the decode mode to “AUTO/PCM”.

Note:

•Changing the playback source (e.g. AM/FM) will automat- ically return the decode mode to “AUTO/PCM”.

When a decode mode which differs from the type of disc being played is selected

Insert a DVD disc in the center unit to display the type of audio be- ing played in the Decode mode indicator on the display window. Audio cannot be played if a decode mode which differs from the displayed mode is selected.

The selected decode mode flashes to indicate that the selected de- code mode does not allow audio playback.

Example: When DTS is selected as the decode mode for Dolby digital audio.
