To maximize the effectiveness of ASA processing, configure a 7.1-channel speaker setup in which the rear speakers are placed close together facing the center of the listening space.

•Select APART if the distance between the rear speakers is greater than 4 feet (1.2m).

•Select CLOSE if the distance between the rear speakers is greater than 1 foot (0.3m), but less than 4 feet (1.2m).

•Select TOGETHER if the distance between the rear speakers is less than 1 foot (0.3m).
