Center Width
0 to 3 to 7
With this setting, you can adjust the width of the sound
from the center speaker when using the Dolby Pro Logic
IIx Music listening mode. Normally, if you're using a
center speaker, the center channel sound is output from
only the center speaker. (If you're not using a center
speaker, the center channel sound will be distributed to the
front left and right speakers to create a phantom center).
This setting controls the front left, right, and center mix,
allowing you to adjust the weight of the center channel
sound.

PL IIz Height Gain
Low
Mid
High
The Height Gain Control in Dolby Pro Logic IIz enables
the listener to select how much gain is applied to the front
high speakers. There are three settings, "Low", "Mid" and
"High", and the front high speakers are accentuated in that
order. While "Mid" is the default listening setting, the
listener may adjust the Height Gain Control to their
personal preference.
Note
• If the "Front High" setting is set to "None"
setting cannot be selected.
• If the "Powered Zone 2" setting is set to "Yes" and Zone 2 is
turned on, this setting cannot be selected.
■
Dolby EX
Auto:
If the source signal contains a Dolby EX flag, the
Dolby EX or THX Surround EX listening mode is
used.
Manual:
You can select any available listening mode.
This setting determines how Dolby EX encoded signals are
handled. This setting is unavailable if no surround back
speakers are connected. This setting is effective with
Dolby Digital, Dolby Digital Plus and Dolby TrueHD only.
Note
• If the "Surround Back" setting is set to "None"
this setting cannot be selected.
• If the "Powered Zone 2/3" setting is set to "Yes" and Zone 2/3 is
turned on, this setting cannot be selected.
■
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
(➔ page 60), this
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.
