SOUND FIELD OPTIONS

ADDITIONAL

INFORMATION

You can adjust the values of certain digital sound field

parameters so that the sound fields are recreated

accurately in your listening room. The following

parameters are not always found in every program.

1 Press TOP on the GUI remote.

2 Select Stereo/Surround, then press h.

3 Select the desired sound field program, then

press h to access and adjust.

■ DSP Level (DSP level)

This parameter adjusts the level of all 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 direct sound.

Control range: –6 dB – +3 dB

■ Init. Delay (Initial delay)

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. 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 (Room size)

This parameter adjusts the apparent size of the sound field.

The larger the value, the larger the sound field becomes.

As sound is repeatedly reflected around a room, the larger

that room 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 – 2.0
