■Sound field parameter descriptions

You can adjust the values of certain digital sound field parameters so that the sound fields are recreated accurately in your listening room. Not all of the following parameters are found in every program.

Sound field parameter	Features
Decoder Type	Decoder type. Selects the decoder used with the SUR. DECODE or MOVIE programs. See
	pages 75 and 76 for details.
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. Delay

Sur. Init. Delay

SB. Init. Delay

Initial delay. Presence, surround, and surround back initial delay. Changes the apparent distance 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 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 (Init. Delay)

1 to 49 ms (Sur. Init. Delay and SB. Init. Delay)
