Creating Realistic Sound Fields
I DSP (Digital Signal Processor) Modes
DSP modes have been designed to create important acoustic
surround elements.
The sound heard in a hall, a theater, a pavilion, a dance club, or a
live club 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.
These indirect sounds are important elements of the acoustic
surround effects.
The following DSP modes are provided with this unit.
THEATER : Gives the feeling of a theater.
HALL : Gives clear vocal and the feeling of a concert
hall.
LIVE CLUB : Gives the feeling of a live music club with a low
ceiling.
DANCE CLUB : Gives a throbbing bass beat.
These DSP modes can be used to add the acoustic surround effects
while reproducing stereo analog software or Linear PCM digital
software, and can give you a real "being there" feeling.
When one of the DSP modes is selected, the DSP indicator lights up
on the display.
