Creating Realistic Sound Fields

■ All Channel Stereo

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 output through the center speaker.

All Channel Stereo can be used while reproducing 2 channel stereo

software, either analog or digital except Dolby Digital and DTS

Digital Surround.

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

on the display.

■ 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.

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.

These DAP modes can be used to add the acoustic surround effects

while reproducing 2 channel stereo software—either analog or

digital except Dolby Digital and DTS Digital Surround—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.
