SOUND FIELD OPTIONS
Rev. Delay (Reverberation delay)
This parameter adjusts the time difference between the
beginning of the direct sound and the beginning of the
reverberation sound. The larger the value, the later the
reverberation sound begins. A later reverberation sound
makes you feel like you are in a larger acoustic
environment.
Control range: 0 – 250 msec
Source sound

Reverberation
REV.DELAY
Rev. Level (Reverberation level)
This parameter adjusts the volume of reverberation sound.
The larger the value, the stronger the reverberations
become.
Control range: 0 – 100%

Initialize (Initialize)
This parameter initializes each sound field program.
Choices: YES, NO
Sur.Init.Delay (Surround initial delay)
This parameter adjusts the delay between the direct sound
and the first reflection in the surround sound field.
Control range: 1 – 49 msec
Sur.Room Size (Surround room size)
This parameter adjusts the apparent size of the surround
sound field.
Control range: 0.1 – 2.0
Sur.Liveness (Surround liveness)
This parameter adjusts the apparent reflectivity of the
virtual walls in the surround sound field.
Control range: 0 – 10
SB Init.Delay
(Surround back initial delay)
This parameter adjusts the delay between direct sound and
the first reflection in the surround back sound field.
Control range: 1 – 49 msec
SB Room Size
(Surround back room size)
This parameter adjusts the apparent size of the surround
back sound field.
Control range: 0.1 – 2.0
SB Liveness (Surround back Liveness)
This parameter adjusts the apparent reflectivity of the
virtual wall in the surround back sound field.
Control range: 0 – 10
