To change sound field parameter settings to suit your listening environment, see page 66 for details.

Sound field parameter	Features
DSP LEVEL	DSP level. Adjusts the level of all the DSP effect sounds within a narrow range. Depending on
	the acoustics of your listening room, you may want to increase or decrease the DSP effect level
	relative to the level of the direct sound.
	Control range: –6 dB to +3 dB
INIT.DLY	Initial delay. Presence, surround, and surround back initial delay. Changes the apparent distance
P.INIT.DLY	from the source sound by adjusting the delay between the direct sound and the first reflection
	heard by the listener. The smaller the value, the closer the sound source seems to the listener. The
S.INIT.DLY
	larger the value, the farther it seems. For a small room, set to a small value. For a large room, set
SB INI.DLY
	to a large value.
	Control range: 1 to 99 ms (INIT.DLY and P.INIT.DLY)
	1 to 49 ms (S.INIT.DLY and SB INI.DLY)
