Onkyo Adjusting Audyssey DSX and LFE Level Settings for Superior Sound Quality

■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.

DTS

■Neo:6 Music Center Image

`0 to 2 to 5

The DTS Neo:6 Music listening mode creates 6-channel surround sound from 2-channel stereo sources. With this setting, you can specify by how much the front left and right channel output is attenuated in order to create the center channel.

Changing the value from “0” to “5” will spread the sound of the center channel to left and right (outwards).

Audyssey DSX™

■Soundstage

`–3dB to Reference to +3dB

With this setting, you can adjust the sound stage when using Audyssey DSX.

Note

•This listening mode can be selected only when all the following conditions are satisfied:

–The center speaker is connected.

–The front high and front wide speakers are connected.

Theater-Dimensional

■Listening Angle

`Wide:

Select if the listening angle is 40 degrees.

`Narrow:

Select if the listening angle is 20 degrees. With this setting, you can optimize the Theater- Dimensional listening mode by specifying the angle of the front left and right speakers relative to the listening position. Ideally, the front left and right speakers should be equidistant from the listening position and at an angle close to one of the two available settings.

Front left speaker	Front right speaker
	20°/40°

LFE Level

■Dolby Digital*1, DTS*2, Multich PCM, Dolby TrueHD, DTS-HD Master Audio, DSD*3

`–QdB,–20dB,–10dB, or 0dB

With these settings, you can set the level of the LFE (Low Frequency Effects) channel individually for each input sources.

If you find that low-frequency effects are too loud when using one of these sources, change the setting to –20 dB or

–QdB.

*1	Dolby Digital and Dolby Digital Plus sources
*2	DTS and DTS-HD High Resolution sources
*3	DSD (Super Audio CD) sources	En
