to optimize the listening experience for THX Ultra2 listening
modes. The ASA parameter is not available unless side and rear
speakers are present and the 5.1

To maximize the effectiveness of ASA processing, it is recommended
to configure a 7-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).
Note:
When the 7/5 button is used to toggle between 7- and
5-channel playback, the SDP-40 automatically:
• Activates ASA processing during 7-channel
playback and deactivates ASA processing during
5-channel playback.
