TOM Dolby Pro-Logic Surround options, or 3CH LOGIC .

right speakers play the center-channel bass sounds.
WIDE — Select this mode if you use a medium or large center speaker. The cen-
ter speaker plays the center-channel bass sounds.
PHANTOM — Select this mode if you have no center speaker. All center-channel
sound comes from the front left and right speakers.
