Using the Listening Modes—Continued
DTS-ES Discrete
This mode is for use with DTS-ES Discrete soundtracks
that use a discrete surround-back channel for true
6.1/7.1-channel playback. The seven totally separate
audio channels provide better spatial imaging and 360-
degree sound localization, perfect for sounds that pan
across the surround channels. Use it with DVDs that bear
the DTS-ES logo, especially those with a DTS-ES Dis-
crete soundtrack.
DTS-ES Matrix
This mode is for use with DTS-ES Matrix soundtracks
that use a matrix-encoded back-channel for 6.1/7.1-
channel playback. Use it with DVDs that bear the DTS-
ES logo.
DTS-HD High Resolution
Developed for use with HDTV, including the new video
disc formats Blu-ray and HD DVD, this is the latest mul-
tichannel audio format from DTS. It supports up to 7.1
channels with 96 kHz/24-bit sampling rate and signal
resolution.
DTS-HD Master Audio
Designed to take full advantage of the additional storage
space offered by the new Blu-ray and HD DVD disc for-
mats, this new DTS format offers up to 7.1 discrete chan-
nels of uncompressed digital audio with 96 kHz/24-bit
sampling rate and signal resolution.
The AV receiver supports 7.1-channel sources up to
96 kHz and 5.1-channel sources up to 192 kHz.
Neural THX 5.1/7.1
Neural-THX Surround employs psychoacoustic fre-
quency domain processing, which allows delivery of a
more detailed sound stage, with superior channel separa-
tion and localization of audio elements. The Neural THX
5.1 and Neural THX 7.1 modes can expand any 2-chan-
nel stereo source for 5.1- or 7.1-channel playback,
respectively. Use them with CD, radio, cassette, TV,
VHS, DVD, and other 2-channel stereo sources, includ-
ing video games. Neural-THX Surround can also be
used by broadcasters to encode and transmit surround-
sound content over a stereo signal, which listeners can
enjoy as either surround sound or normal stereo. XM
Satellite Radio, for example, is using Neural-THX Sur-
round on select channels, which the AV receiver can
expand from 5.1 channels to 7.1 channels.
DSD
DSD stands for Direct Stream Digital and is the format
used to store digital audio on Super Audio CDs (SACD).
This mode can be used with SACDs that feature multi-
channel audio.
THX
Founded by George Lucas, THX develops stringent stan-
dards that ensure movies are reproduced in movie the-
aters and home theaters just as the director intended.
• THX Cinema
This mode is for watching movies, which are typi-
cally recorded and edited on the assumption that they
will be played in a sizable place like a movie theater.
It carefully optimizes the tonal and spatial character-
istics of the soundtrack for reproduction in the
smaller home-theater environment. It can be used
with 2-channel sources processed with other for-
mats, and multichannel sources. Surround back
speaker output depends on the source material and
the selected listening mode.
• THX Ultra2 Cinema
This mode expands 5.1-channel sources for 7.1-
channel playback. It does this by analyzing the com-
position of the surround source, optimizing the
ambient and directional sounds to produce the sur-
round back channel output.
• THX Music Mode
This mode is designed for use with music. It expands
5.1-channel sources for 7.1-channel playback.
• THX Games Mode
This mode is designed for use with video games. It
can expand 2-channel and 5.1-channel sources for
6.1/7.1-channel playback.
• THX Surround EX
This mode expands 5.1-channel sources for 6.1/7.1-
channel playback. It's especially suited to Dolby
Digital EX sources. THX Surround EX, also known
as Dolby Digital Surround EX, is a joint develop-
ment between Dolby Laboratories and THX Ltd.
