SETUP

Setting sound program parameters (Sound Program menu)

Liveness

Surround Liveness

Surround Back Liveness

Liveness. Surround and surround back liveness. Adjusts the

reflectivity of the virtual walls in the hall by changing the rate at

which the early reflections decay. The early reflections of an audio

source decay much faster in a room with acoustically absorbent

wall surfaces than in one which has highly reflective surfaces. A

room with acoustically absorbent surfaces is referred to as “dead,”

while a room with highly reflective surfaces is referred to as “live.”

This parameter lets you adjust the early reflection decay rate and

thus the “liveness” of the room.

Reverb Time

Reverberation time. Adjusts the amount of time taken for the

dense, subsequent reverberation sound to decay by 60 dB at 1 kHz.

This changes the apparent size of the acoustic environment over an

extremely wide range. Set a longer reverberation time to get more

sustaining reverberation sound, and set a shorter time to get

articulate sound.

Reverb Delay

Reverberation delay. 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 as if you are in a larger acoustic environment.
