Creating realistic sound fields

DTS**

DTS is another digital signal compression method, developed by Digital Theater Systems, Inc., and enables multi-channel encoding and decoding.

DTS Digital Surround is another discrete 5.1 channel digital audio format available on CD, LD, and DVD software.

Compared to Dolby Digital, the DTS Digital Surround format has a lower audio compression rate, which enables it to add breadth and depth to the sounds reproduced. As such, DTS Digital Surround features natural, solid and clear sound.

•To enjoy the software encoded with DTS Digital Surround, connect the source component using the digital terminal on the rear of this receiver. (See page 10.)

■DSP (Digital Signal Processor) modes

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 create these important elements, and give you a real “being there” feeling.

Reflections from behind

Early reflections

Direct sounds

DAP modes can be used when the front and surround 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: Reproduces the spatial feeling of a live music club with a low ceiling.

DANCE CLUB: Reproduces the spatial feeling of a rocking dance club.

HALL:Reproduces the spatial feeling of a hall for classical recitals.

PAVILION: Reproduces the spatial feeling of an exhibition hall.

These DAP modes can be used to add acoustic surround effects while reproducing 2 channel stereo software, either analog or Linear PCM digital signal, 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.

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 surround 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 analog or Linear PCM digital signal.

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