Dimension
`
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” setting is set to “None” (➔ page 52), 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 52), this setting cannot be selected.
•If the “Front High” or “Front Wide” setting is enabled (➔ page 52), this setting is fixed to “Manual”.

■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.
