Setup: Sound: Sound Modes: PRESETNAME: Advanced Settings: Spatial Controls: Envelopment
The Envelopment setting allows you to
set the desired amount of perceived
width or spaciousness from your
surround and back loudspeakers. At its
minimum setting, the surround
information will appear to collapse to a
centre back phantom location. At its
maximum setting, the surround
information will appear to be very wide.
Note that this setting has no effect on
the front loudspeaker channels. Changes
in the Envelopment setting will have no
effect on the signal when the Processing
is set to 1:1 or Downmix.
Setup: Sound: Sound Modes: PRESETNAME: Advanced Settings: Spatial Controls: Reset to Default
Selecting Reset to Default in this menu
will return all Spatial Control settings
(Balance L/R, Fader B/F, Processing,
Surround, Height, Stage Width, and
Envelopment) to their factory default
setting for the current Sound Mode.
Note that other Sound Modes will not
be affected.
Setup: Sound: Sound Modes: PRESETNAME: Advanced Settings: Dynamics Control: Compression
There are many instances where it is
desirable to reduce the dynamic range
of the audio signal. For example,
television advertisements are typically
much louder than the programme they
interrupt, and should be tamed. Films on
DVD or Blu-ray often have large
differences between the quietest and
loudest moments, making it difficult to
watch movies late at night without
disturbing the rest of the family. At a
party, the music should be kept at a
constant level.
Consequently, the television has the
ability to reduce (or compress) the
dynamic range of audio signals by
making quiet passages louder and loud
passages quieter. The amount of
compression applied to the audio signal
for the current Sound Mode is
determined using the Compression
setting in the Advanced Settings of the
Dynamics Control.
Note that the Dynamics Control must be
turned ON in the basic menus in order
for the Dynamics Control Advanced
Settings to have an effect.
Options: OFF / MEDIUM / MAXIMUM.
