DTS-ES Matrix
This is DTS with an added surround back
channel for 6.1 surround sound. Use it to
provide 6.1 channel surround playback
with program material recorded in DTS 5.1
format. Since DTS 5.1 program material
contains surround back channel informa-
tion, all channels can be reconstructed for 6.1-channel
playback. Use this mode with CDs, DVDs, or LDs that
bear the DTS-ES or DTS logo.
Neo:6
This mode provides 6.1-channel playback from 2-chan-
nel sources. It offers six full-bandwidth channels with
excellent separation. There are two modes of operation:
Cinema mode for movies, and Music mode for listening
to music.
Cinema mode simulates the realistic sense of movement
that you get with 6.1-channel surround sound sources.
Use this mode with videos, DVDs, and TV programs that
feature stereo sound.
Music mode uses the surround channels to simulate a
natural sound field that cannot be produced with conven-
tional stereo. Use this mode with stereo material such as
music CDs.
THX Cinema (DTR-6.5 only) or
THX Ltd, founded by George Lucas, develops quality
assurance programs for ensuring that movies are repro-
duced in movie theaters and home theaters just as the
director intended. THX technology is used to eliminate
spatial errors that can occur when a movie soundtrack is
adapted for use in smaller home theaters, ensuring faith-
ful reproduction.
This mode is ideal for watching a movie with a
soundtrack recorded and edited especially for playback
in the spaciousness of a typical movie theater.
THX Surround EX (DTR-6.5 only)
This format was jointly developed by Dolby Laborato-
ries and THX Ltd. especially for home theater use. It’s
based on Dolby Digital EX technology. It adds an extra
surround channel to the existing front left, front right,
center, surround left, surround right, and LFE (sub-
woofer) channels, making a total of 6.1 channels. (For
best results with DVDs that feature THX Surround EX,
use a THX-certified THX speaker system.)

speaker is turned off and the surround channels are
emphasized in order to widen the stereo image. In addi-
tion, it simulates the natural reverberation of a large hall.

Suitable for acoustic instrument sounds, vocals, and jazz
music. By emphasizing the front stereo image, it simu-
lates the stage-front experience.

this mode creates a lively sound field with a powerful
acoustic image, like being at a club or rock concert.

TV studio. In addition, it adds surround effects to the
entire sound and adds clarity to voices.

sports programs. It provides a natural surround sound
with movement in the surround back speakers, creating
a sound with a live feeling to it.

by the other speakers, giving presence to even mono
material.

surround back channels create a stereo image that fills
the entire listening area.

music sounds the same regardless of where you are.
