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 (Initial delay)

Function:

Changes the apparent distance from the source sound by adjusting the delay between the direct sound

 

and the first reflection heard by the listener.

Description:

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 msec
