is Pro Logic, or “Stereo” if a stereo signal is being input.
NOTE: Many DVD discs support multi-soundtrack options, so the
digital signal input to the DX 333 will be determined by the DVD
player settings. The DX 333 stores the last settings when
switched off, and will restore these settings when next switched on.

No sound from one or more channels:
• There is a short delay after switching on before the system starts
functioning.
• Check all speakers connections are correct and all leads are
secured.
• Check all input leads are correctly wired and all connectors are
securely tted.
• Check the settings of the input device (DVD player, etc.)
• Check channel volume settings.
• Check that the MUTE or STANDBY function is not selected.
Volume level low:
• Check master volume setting.
• Check individual channel volume settings.
Sound distortion:
• Check all inputs are correctly wired up.
• Check input device settings.
• Check that the volume level is not set too high.
Remote control not operating correctly:
• Check the battery, if the remote controller only works when close
