listening position. Use the test to adjust the volume
of the speakers to the same level.

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 W S to scroll up and
down through the delay amount, which you can
set at anything between 0 and 300 ms.
DRC (Dynamic Range Control)
This function allows you to listen to a movie at a
lower volume without losing clarity of sound.
[Off]
Turns off this function.
[On]
Compress the dynamic range of the Dolby
Digital, Dolby Digital Plus or Dolby TrueHD
audio output.
[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.

Note
The DRC setting can be changed only when a
disc is not inserted or the unit is in complete
stop mode.
