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 level of the direct sound.

Control range:

–6 dB – +3 dB

■INIT. DLY (Initial delay)

Function:

This parameter 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 – 99 msec

■ROOM SIZE/P. ROOM SIZE (Room size)

Function:

This parameter 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.

0.1 – 2.0
