P. INIT. DLY (Presence Initial Delay)
Adjusts the delay between the direct sound and the first reflection
on the presence side of the sound field. The larger the value, the later
the first reflection begins.
Control Range:
1 – 49 milliseconds
P. ROOM SIZE (Presence Room Size)
Adjusts the apparent space size of the front presence sound field.
The larger the value, the longer the interval between reflections
becomes, which increases the depth of the sound source.
Control Range:
0.1 – 2.0
S. INIT. DLY (Surround Initial Delay)
Adjusts the delay between the direct sound and the first reflection
on the rear surround side of the sound field. The larger the value, the
later the first reflection begins.
This parameter is available only when an AC-3 RF signal or digital
*
AC-3 input signal is input to this unit. When another signal is
input, the value of this parameter is shown by "_ _".
Control Range:
1 – 49 milliseconds
S. DELAY (Surround Delay)
Adjusts the delay between the direct sound and the first reflection
on the rear surround side sound field. The larger the value, the later
the surround sound field is generated.
This parameter is available only when an AC-3 RF signal or digital
*
AC-3 input signal is input to this unit. When another signal is
input, the value of this parameter is shown by "_ _".
Control Range:
When the Dolby Pro Logic Surround is decoded:
15 – 30 milliseconds
When the Dolby Surround AC-3 is decoded:
0 – 15 milliseconds
When a program without Dolby Surround decoding is used:
1 – 49 milliseconds
S. ROOM SIZE (Surround Room Size)
Adjusts the apparent space size of the rear surround sound field.
The larger the value, the larger the surround sound field becomes.
Control Range:
0.1 – 2.0
S. LIVENESS (Surround Liveness)
Adjusts the apparent reflectivity of the walls on the rear surround
sound field. The larger the value, the more reflective the surround
sound field becomes.
Control Range:
0 – 10
