DRC (Dynamic Range Control)
This function allows you to listen to a movie at a
lower volume without losing clarity of sound.
[Auto]
The dynamic range of the Dolby TrueHD audio
output is specified by itself.
And the dynamic range of the Dolby Digital
and Dolby Digital Plus are operated as same as
the [On] mode.
[On]
Compress the dynamic range of the Dolby
Digital, Dolby Digital Plus or Dolby TrueHD
audio output.
[Off]
Turns off this function.
HD AV Sync
Sometimes Digital TV encounters a delay between
picture and sound. If this happens you can
compensate by setting a delay on the sound so
that it effectively ‘waits’ for the picture to arrive:
this is called HD AV Sync. Use A D to scroll up and
down through the delay amount, which you can
set at anything between 0 and 300 ms.
Auto Volume
With Auto Volume function on, the unit
automatically adjusts the outputted volume level to
make it raised or lowered if the sound is too loud or
small. So you can enjoy the sound at comportable
level not too loud or small.
