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 8.)
■ 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.

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 analogue 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 analogue or Linear PCM digital signal.
• When All Channel Stereo is selected, the DSP indicator lights up on
the display.
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).
