Dynamic Range Control (DRC)

With the DVD*1 format, you can hear a program’s soundtrack in the most accurate and realistic presentation, thanks to digital audio technology. However, you may wish to compress the dynamic range of the audio output (the difference between the loudest sounds and the quietest ones). Then, you may listen to a movie at a lower volume without losing clarity of sound. Set DRC to On for this effect.

*1: Dolby Digital only

Vocal

Set Vocal to On only when a multi-channel karaoke DVD is playing. The karaoke channels on the disc will mix into normal stereo sound.

HD AV Sync

When using Digital TV.

Sometimes AV signal could not be transmitted simultaneously because of later transmission of video signal compared to audio signal.

Because it takes some time to convert analog video signal to digital one in the Digital TV.

And It means that you may not enjoy picture on the screen and sound from speaker at the same time even though it is one scene.

In the HD AV Sync menu, you could adjust delay time to audio signal for simultaneous AV signal transmission

Delay time could be set up with 10msec unit. (0 ~ 300ms)

Delay time is different according to each TV Brand. So you need to adjust optimal delay time complying with your TV.
