–3 to 0 to +3
With this setting, you can move the sound field forward or 
backward when using the Dolby Pro Logic IIx Music 
listening mode. Higher settings move the sound field 
backward. Lower settings move it forward.
If the stereo image feels too wide, or there’s too much 
surround sound, move the sound field forward to improve 
the balance. Conversely, if the stereo image feels like it’s 
in mono, or there’s not enough surround sound, move it 
backward.
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” settings is set to “None” (
page 46), 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” (
➔
page 46),
this setting cannot be selected.
• If the “Front High” or “Front Wide” setting is enabled
(
page 46), this setting is fixed to “Manual”.
■
Dolby Volume
`
Off
`
On
Dolby Volume automatically adjusts the difference in 
volume levels which can occur between different content 
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.
