Divergence controls
The 3 divergence controls (Front, F/R, and Rear) determine the attenuation curves used when positioning sound sources for X-axis front, Y-axis (front/rear), and X-axis back. If all 3 controls are set to 0 %, positioning a sound source on a speaker sets all other speakers to zero level. With higher values, the other speakers receive a percentage of the sound source.
Blue horizontal and vertical lines visualize the effects when changing the divergence settings.
For example, by using the front divergence, you can acoustically intensify the distance from the action on screen as perceived by the audience.
At 0 % the perception is very focused (concentrated in one spot).
At 100 % the perception is very diffuse (hard to locate).
The Center Distribution value and the front divergence are combined. If the front divergence is set to 100 %, the Center Distribution has no effect.
