JVC RX-E100RSL manual Creating Realistic Sound Fields, DAP Digital Acoustic Processor Modes, Hall

■DAP (Digital Acoustic Processor) Modes

DAP modes have been designed to create important acoustic surround elements.

The sound heard in a hall, live club, dance club 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 to the right).

These indirect sounds are important elements of the acoustic surround effects.

The following DAP modes are provided with this unit.

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 stereo analog software or Linear PCM digital software, and can give you a real “being there” feeling.

•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 if it is connected).

•When one of the DAP modes is selected, the DSP indicator lights up on the display.
