Loudness boost
The loudness function increases the level of the low- and high-frequency content as the
volume level is decreased. The maximum amount of level increase in bass and treble can
be set under
Bass max and treble max
.
Note that
Loudness
boost
will only have effect if
Loudness
in the
Sound
menu is
activated.
Spatial control
The spatial control function allows you to adjust many aspects of the perceived sound,
including surround settings, stage width, envelopment and more.
Balance and Fader
: Re-direct input signal to different output channels in your
speaker setup. For example, adjusting the balance l/r all the way to the left will
direct all the signals only to the speakers in your setup that have a speaker role
on the left (that is left front, left surround, etc.) and adjusting the fader b/f all the
way to the left will direct all the signals only to the speakers in your setup that
have speaker roles as rear speakers (that is right back, left back, etc.).
Processing
: In many cases, the number of input channels in the audio signal does
not match the number of loudspeakers in your configuration. For example, you
may have two speakers, but the input signal is from a 7.1-channel Blu-ray. In this
case, the signal is "downmixed" to the two speakers and you can hear all the
components of the signal. To do this, you must select
Downmix
. Conversely, you
may have a large system with seven main speakers and a subwoofer (7.1 channel
system) and you would like to distribute the two channels from a CD to all
speakers. In this case, the signal must be "upmixed" to all speakers.
True
image
is the processor that accomplishes these tasks dynamically. If you select
the setting
1:1
instead, the signals are passed directly through to the speakers.
Surround
: Determines the balance between the sound stage (in the front) and
the surround information from the True Image processor. Note that the surround
controller has no effect on the signal when
Processing
is set to
1:1
or
Downmix
.
Height
: This setting determines the level of the feed to all loudspeakers in your
configuration with a “height” speaker role. It will have no effect on other
loudspeakers in your system. If the controller is set to minimum, then no signal
will be sent to the “height” loudspeakers. Note that, if the
LFE input to
ceiling
setting in the
Speaker groups
menu is
Yes
, then the height control will
determine the level of the ceiling loudspeaker. In this case, to ensure that the
ceiling loudspeaker is calibrated to the correct level, the
Height
setting should
be set to maximum.
Stage width
: Determines the width of the front images in the sound stage. At a
minimum setting, the images will collapse to the centre of the front. At a
maximum setting, images will be pushed to the sides of the front sound stage.
This allows you to control the perceived width of a band or music ensemble
without affecting the information in the surround and back speakers.
Envelopment
: This 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
location.
Dynamics control
Many soundtracks and music recordings have a very wide dynamic range. This means
that there is a very large difference between the quietest and loudest moments.
Consequently, if you set your volume level to be able to hear the quiet sections, the loud
sections become very loud. With
Dynamics control
option you can reduce the difference
by making the quiet sound louder and the loud sound quieter.
Compression
: TV advertisements are typically much louder than the programme
they interrupt, and movies often have large differences between the quietest
and loudest moments. Consequently, the
Compression
feature allows the
television to reduce (or compress) the dynamic range of audio signals.
