JVC LVT0858-001A DAP Digital Acoustic Processor modes All Channel Stereo, Creating sound field

■ DAP (Digital Acoustic Processor) modes ■ All Channel Stereo

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.

This mode can reproduce a larger stereo sound field using all the connected (and activated) speakers.

All Channel Stereo can be used when the front and rear 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 mixed and output through the center speaker.

All Channel Stereo can be used while reproducing 2-channel stereo software, either analogue or Linear PCM digital signal.

•When All Channel Stereo is selected, the DSP indicator lights up on the display.
