DSD – SACD Direct Stream Digital (DSD) data is output over HDMI without any conversion.
For the analog audio outputs, DSD data is converted into an analog signal directly by the
internal DAC. If you use a receiver that supports HDMI v1.2a with DSD over HDMI, or you
prefer the sound quality of straight DSD to analog, please select this option.
7. A/V Sync: Allows you to add a slight delay to the audio so it is synchronized to the video. You
may use the LEFT/RIGHT ARROW buttons on the remote to decrease/increase the audio delay.
The delay can be adjusted in 10ms steps and within the range of -100ms to +200ms. The delayed
time will be applied to all output terminals including HDMI, Coaxial, Optical, Stereo (or 7.1)
outputs.
NOTE

The actual audio delay effect might be different for each of the output terminals due to
the different audio process algorithms and signal paths used for each output. Please
adjust this setting based on the actual output terminal in use.

The negative adjustment values are for cancelling out the audio delay that the player
automatically applies. Depending on the video source and the time it takes to process
the video, the main decoder chip automatically applies an audio delay in order to
optimize audio video synchronization. The negative manual settings reduce the
automatic audio delay, while the positive manual settings apply additional delay. Any
negative value setting beyond the player's automatic delay will be treated as completely
cancelling the automatic delay. For example, if the A/V Sync value is manually set to
100ms and for the current video source the player applies a 70ms automatic audio
delay, the final result is that the 70ms audio delay gets cancelled and the audio is not
delayed at all. It is not possible to put audio ahead of video using this setting.
