Digital sound field parameter descriptions
You can adjust the values of certain digital sound field parameters so the sound fields are recreated accurately in your
listening room. Not all of the following parameters are found in every program.
■ DSP LEVEL
Function: This parameter adjusts the level of all the DSP effect sounds within a narrow range.
Description: Depending on the acoustics of your listening room, you may want to increase or decrease the DSP
effect level relative to the direct sound.
Control Range: –6 dB to +3 dB
■ DELAY
Function: Adjusts the time difference between the beginning of the sound from the main speakers and the
beginning of the sound effect from the rear speakers. The larger the value, the later the sound effect is
generated.
Control range: 1 to 99 ms (Control range varies depending on the input source and the DSP program you use.)
For 6ch Stereo
Function: These parameters adjust the volume level for each channel in 6-channel stereo mode.
Control range: 0 to 100%
■ CT LEVEL (Center level)
■ RL LEVEL (Rear left level)
■ RR LEVEL (Rear right level)
■ RC LEVEL (Rear center level)
For PRO LOGIC II Music
■ PANORAMA
Function: Extends the front stereo image to include the surround speakers for a wraparound effect.
Choices: OFF/ON, initial setting is OFF.
■ DIMENSION
Function: Gradually adjusts the soundfield either towards the front or towards the rear.
Control range: –3 (towards the rear) to +3 (towards the front), initial setting is STD (standard).
■ CT WIDTH (Center width)
Function: Adjusts the center image from all three front speakers to varying degrees. A larger value adjusts the
center image towards the main left and right speakers.
Control range: 0 (center channel sound is output only from center speaker) to 7 (center channel sound is output only
from main left and right speakers), initial setting is 3.
For DTS Neo:6 Music
