TrueHD Loudness Management
`
Off
`
On
This setting specifies whether or not to apply the Late
Night processing on a Dolby TrueHD source.
Note
• When this setting is set to “
Off
”, the Late Night function for
Dolby TrueHD sources is automatically fixed to “
Off
”.
• When this setting is set to “
Off
”, the Dialogue Normalization
information is not available for Dolby TrueHD sources.
■
Dolby Volume
`
Off
`
On
Dolby Volume automatically adjusts the difference in
volume levels which can occur between different contents
or source components, freeing the user from having to
make volume adjustments. Also, by adjusting the
frequency balance according to the playback volume, it
recreates the original source audio. Dolby Volume
therefore provides comfortable listening, effectively
controlling the volume level difference without unnatural
changes in volume or sound quality to recreate the balance
and nuance of the source audio.
Note
• When the “
Dolby Volume
” setting is set to “
On
”,
“
Dynamic EQ
” and “
Dynamic Volume
” will be set to “
Off
”.
• If you would like to use
Dolby Volume
in THX listening modes,
set the “
Loudness Plus
” and “
Preserve THX Settings
” settings
to “
Off
” and “
No
”, respectively.
• When “
Dolby Volume
” is set to “
On
”, the Late Night function
cannot be set.
■
Volume Leveler
`
Off
`
Low
:
Low Compression Mode activated.
`
Mid
:
Medium Compression Mode activated.
`
High
:
High Compression Mode activated. This setting
affects volume the most, causing all sounds to be of
equal loudness.
“
Volume Leveler
” maintains the perceived loudness of all
contents, coming from different channels or input sources.
Note
• If the “
Dolby Volume
” setting is set to “
Off
”, this setting cannot
be selected.
■
Half Mode
`
Off
`
On
The Half Mode parameter turns Dolby Volume Half Mode
processing on and off.
In off mode, Dolby Volume applies a bass and treble
attenuation to the audio when the system gain exceeds
reference level. This enables a more perceptually flat
listening experience as human ears are more sensitive to
bass and treble at higher levels. Some listeners however,
prefer to have more bass and treble performance at higher
gain levels.
Note
• If the “
Dolby Volume
” setting is set to “
Off
”, this setting cannot
be selected.
• During Half Mode on playback, Dolby Volume does not apply a
bass and treble attenuation when the system volume exceeds
reference level, thereby boosting perception of high and low
frequencies.

Neo:X Music
Center Image
`
0
to
2
to
5
The DTS Neo:X Music listening mode creates 9-channel
surround sound from 2-channel stereo sources. With this
setting, you can specify by how much the front left and
right channel output is attenuated in order to create the
center channel.
Changing the value from “
0
” to “
5
” will spread the sound
of the center channel to left and right (outwards).
Dialogue Normalization
Dialogue Normalization (DialogNorm) is a feature of
Dolby Digital, which is used to keep the programs at the
same average listening level so the user does not have to
change the volume control between Dolby Digital,
Dolby Digital Plus and Dolby TrueHD programs. When
playing back software which has been encoded in Dolby
Digital, Dolby Digital Plus and Dolby TrueHD,
sometimes you may see a brief message in the front
panel display which will read “
DialogNorm: X dB
” (X
being a numeric value). The display is showing how the
program level relates with THX calibration level. If you
want to play the program at calibrated theatrical levels,
you may wish to adjust the volume. For example, if you
see the following message: “
DialogNorm: + 4 dB
” in
the front panel display, to keep the overall output level at
THX calibrated loudness, just turn down the volume
control by 4 dB. However, unlike a movie theater where
the playback loudness is preset, you can choose your
preferred volume setting for best enjoyment.
