7 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.
The following DAP modes are provided with this system.
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 Linear PCM, 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 window.
