SOUND FIELD PROGRAM PARAMETER EDITING

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.)
