I DAP (Digital Acoustic Processor) modes
DAP modes have been designed to create important acoustic
surround elements.
The sound heard in a live club, dance club, hall or pavilion consists
of direct sound and indirect sound—early reflections and reflections
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
surround effects. The DAP mode can reproduce a realistic sound
field by adding these indirect sounds.
DAP modes can be used when the front and rear speakers are
connected to this receiver (without respect to the center speaker
connection: no sound comes out of the center speaker even if it is
connected).
The following DAP modes are provided with this receiver:
LIVE CLUB
: Gives the feeling of a live music club with a low
ceiling.
DANCE CLUB : Gives a throbbing bass beat.
HALL : Gives clear vocal and the feeling of a concert
hall.
PAVILION : Gives the spacious feeling of a pavilion with a
high ceiling.
These DAP modes can be used to add the acoustic surround effects
while reproducing 2 channel stereo software—either analog or
digital except Dolby Digital and DTS Digital Surround—and can
give you a real "being there" feeling.
• When one of the DAP modes is selected, the DSP indicator lights
up on the display.

speakers are connected to this receiver without respect to the
center speaker connection.
If the center speaker is connected and activated, the same phase of
the front left and right signals are output through the center speaker.

software, either analog or digital except Dolby Digital and DTS
Digital Surround.
