Digital output
According to the amplifier or the TV set (with or without inbuilt DTS or Dolby decoder) to
which you connect your DVD player, you will have to define the COAXIAL OUT and
OPTICAL OUT digital signal out sockets so that they can deliver DTS or Dolby Digital digital
signals that may be on a disc that you want to play.
1. In the player menu (with the player running, but no disc in play), highlight the Sound function
and press
OK on the remote control unit (the Sound menu appears).
2. Press to highlight Digital Output and press OK (the settings screen appears).
3. Select Dolby Digital or DTS using the or key and press OK on the remote control
unit to validate your choice.
4. To return to the player menu, press until the menu is displayed on the screen.
Note: By ticking DTS and Dolby Digital you will not have to change this setting again.Your player will
automatically recognise the sound format of a DVD disc in playback and will send the appropriate signal to
the appliance connected to the coaxial and optical out sockets.
If you do not tick either of these two settings the digital sound present on the coaxial and optical out
sockets will be a PCM digital sound for all discs played (in the case of DTS discs no sound will be heard).
If you set the digital outputs on DTS, you must connect it to an amplifier with a DTS decoder, and the DVD
disc that you play must include a DTS sound, otherwise no sound will be heard.
PCM - If the appliance connected to the coaxial and optical sockets does not accept the Dolby or DTS
signals, your player can supply it with PCM (Pulse Code Modulation) signals. In that case, neither Dolby
Digital, nor DTS must be ticked. The linear PCM is a signal recording format used for CDs.
