`–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.
