ADVANCED FEATURES
●LIVENESS
How it Affects the Sound:
This parameter changes the apparent reflectivity of the walls in the hall.
The early reflections from a sound source will lose intensity (decay) much faster in a room with acoustically absorbent wall surfaces than in one which has mostly reflective surfaces. A room with highly reflective surfaces in which the early reflections decay slowly is termed “live”, while a room with absorbent characteristics in which the reflections decay rapidly is termed “dead”. The LIVENESS parameter lets you adjust the early reflection decay rate, and thus the “liveness” of the room.
What it Does:
Changes the rate at which the early reflections decay.
Control Range:
0 – 10.
LIVENESS (Presence Liveness)
Adjusts the apparent reflectivity of the walls on the front presence sound field. The larger the value, the more reflective the front presence sound field becomes.
●REV. TIME (Reverberation Time)
How it Affects the Sound:
The natural reverberation time of a room depends primarily on its size and the characteristics of its inner surfaces. This parameter, therefore, changes the apparent size of the acoustic environment over an extremely wide range.
What it Does:
Adjusts the amount of time it takes for the level of the dense, subsequent reverberation sound to decay by 60 dB (1 kHz).
Control Range:
1.0 – 5.0 seconds.

●REV. LEVEL (Reverberation Level)
This parameter adjusts the volume of the reverberation sound. The larger the value, the stronger the reverberation becomes.
Control Range:
0 – 100%

●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.
Control Range:
When Dolby Surround is decoded: 15 – 30 milliseconds
When Dolby Digital or DTS is decoded: 0 – 15 milliseconds
When a program without Dolby Surround or DTS encoded is used:
15 – 49 milliseconds
