Creating Realistic Sound Fields
■
DSP (Digital Signal Processor) Modes
DSP modes have been designed to create important acoustic
surround elements.
The sound heard in a live house, a hall, a concert, a stadium, or a
theater 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.
LIVE HOUSE : Gives the feeling of a live music house with a
low ceiling.
HALL : Gives clear vocal and the feeling of a concert
hall.
CONCERT : Gives the feeling of a large hall designated
primarily for classical concert.
STADIUM : Gives feeling of an outdoor stadium.
THEATER : Gives the feeling of a theater.
These DSP modes can be used to add the acoustic surround effects
while reproducing stereo analog software, Linear PCM digital
software, or Dolby Surround encoded source and can give you a real
“being there” feeling.
Note:
On some source signals, DSP mode may not work sufficiently. In that
case, select another preferred DSP mode.
Activating the Surround Mode
You can enjoy three kinds of surround—Digital Multichannel
Surround (Dolby Digital and DTS Digital Surround), Dolby Pro
