SOUND FIELD OPTIONS Stereo/Surround menu 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. ■ 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 Source sound Early reflections Level Level INIT. DLY Time Sound source Time INIT. DLY Reflection face 3 Select the desired sound field program, then press h to access and adjust. Small value = 1 ms Large value = 99 ms ■ 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 ■ 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 Level Level Time Sound source Source sound Early reflections Time 110 Small value = 0.1 Large value = 2.0

SOUND FIELD OPTIONS
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
