Customizing Sound Fields
xdts LFE MIX
(dts Low Frequency Effect mix level)
Initial setting: 0 dB
This parameter lets you attenuate the level of the LFE (Low Frequency Effect) channel output from the subwoofer without effecting the level of the bass frequencies sent to the subwoofer from the front, center, or rear channels via the “dts” bass redirection circuitry.
•The level can be adjusted in 1 dB step from
•Selecting MUTING mutes the sound of the LFE channel from the subwoofer. However, the low frequency sounds of the front, center, or rear speakers are output from the subwoofer.
zAbout the level differences in the LFE MIX settings
The “dts LFE” level is set to +10 dB and “LFE MIX” (Dolby Digital) is set to 0 dB. This is because there is an initial difference of 10 dB in the overall mix between the Dolby Digital and dts LFE channel levels. Essentially, with the “dts LFE” level set to +10 dB and the “LFE MIX (Dolby Digital)” level set to 0 dB, approximately the same amounts of LFE channel signal are distributed to the other audio channels in the overall mix.
xD.COMP. (Dynamic range compressor)
Initial setting: OFF
This parameter lets you compress the dynamic range of the sound track.
This may be useful when you want to watch movies at low volumes late at night.
•OFF reproduces the sound track with no compression.
•0.1~ 0.9 allow you to compress the dynamic range in small steps to achieve the sound you desire.
•STD reproduces the sound track with the dynamic range intended by the recording engineer.
•MAX provides a dramatic compression of the dynamic range.
Note
Dynamic range compression is only possible with Dolby Digital sources.
zAbout the Dynamic Range Compressor
This parameter allows you to compress the dynamic range of the soundtrack based on the dynamic range information included in the Dolby Digital signal. “STD” is standard compression, but because many sources have only light compression, you may not notice much difference when using 0.1~ 0.9.
Therefore, we recommend using the “MAX” setting. This greatly compresses the dynamic range and allows you to view movies late at night at low volumes. Unlike analog limiters, the levels are predetermined and provide a very natural compression.
Adjusting the surround parameters
The surround parameters let you customize various aspects of the current sound field. The settings available here are stored individually for each sound field.
1Start playing a program source encoded with
2Press AMP MENU repeatedly on the remote to display <<SURROUND>> on the front panel display.
3Sit at your listening position and select the item to be adjusted using the M/m buttons.
4Adjust the volume level using the </, buttons.
The adjusted value will appear on the front panel display. If you do not operate the remote for a few seconds, the value turns off and is stored in the system.
xEFFECT (Effect level)
Initial setting: (depends on sound mode)
This parameter lets you adjust the “presence” of the current surround effect.
xWALL (Wall type)
Initial setting: center
When sound is reflected off soft materials, such as a curtain, the high frequency elements are reduced. A hard wall is highly reflective and does not significantly effect the frequency response of the reflected sound. This parameter lets you control the level of the high frequencies to alter the sonic character of your listening environment by simulating a softer (S) or harder (H) wall. The center position designates a neutral wall (made of wood).
xREVB. (Reverberation)
Initial setting: center
Before sound reaches our ears, it is reflected (reverberated) many times between the left and right walls, ceiling, and floor. In a large room, sound takes more time to bounce from one surface to another than in a smaller room. This parameter lets you control the spacing of the early reflections to simulate a sonically longer (L) or shorter (S) room.
•The reverberation can be adjusted ±6 from S (short,
•The center position (0) designates a standard room with no adjustment.
