AUDIO MENU

Each DVD disc has a variety of audio output options.
Set the receiver's AUDIO options according to the type
of audio system you use.
Dynamic Range Control (DRC)
With the DVD * 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.
*: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 a Digital TV. Sometimes the AV signal can not
be transmitted simultaneously because of later transmission
of the video signal compared to the audio signal. It takes
some time to convert the analog video signal to a digital one in
the Digital TV. It also means that you may not enjoy the picture
on the screen and the sound from speakers at the same time
even though it is one scene. In the HD AV Sync menu,
you can adjust the delay time to the audio signal for simultaneous
AV signal transmission.
Delay time can be set up with 0msec unit. (0 ~ 300ms)
Delay time is different according to each TV Brand.
So you need to adjust optimal delay time to comply with your TV.
