•Select ON to apply a highpass 55Hz filter to all Main Zone
audio output connectors and listening modes.

proximity of the speakers to the listening room walls.
ASA (ADVANCED SPEAKER ARRAY) ON, OFF
ASA is a proprietary THX technology that processes rear channel signals to
optimize the listening experience for THX Ultra2 listening modes, including
5.1 THX ULTRA2, 5.1 THX MUSIC, DTS THX ULTRA2, DTS THX MUSIC,
5.1a THX ULTRA2, or 5.1a THX MUSIC. Applied to film sources, ASA
processing blends surround channel signals to optimize ambient and direc-
tional surround sounds. Applied to music sources, ASA processing places
surround channel signals on a wide, stable rear soundstage.
ASA processing is not available unless:
• One of the THX ULTRA2 listening modes is activated.
• Both side and rear speakers are present.
The ASA parameter can be changed in any mode, but the change
will have no effect unless the above conditions are met.
To maximize the effectiveness of ASA processing, configure a
7.1-channel speaker setup so 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).
You can use the remote control 7/5 button to toggle between
7- and 5-channel playback. When you use the 7/5 button , the
MC-12 automatically:
• Activates ASA processing during 7-channel playback.
• Deactivates ASA processing during 5-channel playback.
• Switches between the 5.1 THX ULTRA2 and THX, DTS THX ULTRA2
and DTS THX, or 5.1a THX ULTRA2 and 5.1a THX listening modes.
