■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.

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.
