surround element\.

You cannot select DAP modes when playing back DVD
AUDIO.
The sound heard in a live club,
dance
club. hall or pavilion consists
of direct sound and indirect sound--early rctlections and reflection\
from behind. Direct sounds reach the listener directly without any
reflection. On the other hand, indirect sounds are delayed by the
distances of the ceiling and walls (see the diagram below).
These indirect sounds are important elements of the acoustic
sun-ound effects. The DAP
mode cx
reproduce a I-ealistic sound
field
by
adding these indirect sounds.
DAP modes can be used when the front and rear speakers are
connected to this unit (without respect to the center speaker
connection: no sound comes out of the center speaker even if it is
connected).
