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 (DSP level)

Function:	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 level of the direct sound.
Control Range:	–6 dB to +3 dB

■INIT. DLY / P. INIT. DLY (Initial delay)

Function:	Changes the apparent distance the sound source is from the reflection face by adjusting the delay
	between the direct sound and the first reflection heard by the listener.
Description:	The smaller the value, the closer the reflection face seems to the sound source. The larger the value, the
	farther it seems. For a small room, set to a small value. For a large room, set to a large value.
Control range:	1 to 99 ms

■ROOM SIZE / P. ROOM SIZE (Room size)

Function:	Adjusts the apparent size of the surround sound field. The larger the value, the larger the surround
	sound field becomes.
Description:	As the sound is repeatedly reflected around a room, the larger the hall is, the longer the time between
	the original reflected sound and the subsequent reflections. By controlling the time between the
	reflected sounds, you can change the apparent size of the virtual venue. Changing this parameter from
	one to two, doubles the apparent length of the room.
Control range:	0.1 to 2.0
