DTS 5.1

DTS 96/24

DTS (Digital Theater Systems) is an alternative digital format competing
®
with Dolby Digital in both movie theaters and home theater markets. The
basic functions of the DTS system are similar to those of Dolby Digital
(for example, 5.1 discrete channels), however the technical details of
the compression and decoding processes differ somewhat and a DTS
decoder is required.
A recent extension of the DTS encoding system is DTS 96/24 and
the 6.1-channel version DTS-ES 96/24. These recordings provide the
performance of a 96kHz sampling rate while still using the actual 48kHz
sampling rate of standard DTS discs.
Like Dolby Digital, DTS can only be used on a digital recording and,
therefore, is only available for home use on LaserDiscs, DVDs, or other
digital formats. To use the receiver's DTS decoder, you must connect your
DVD player to the receiver's digital inputs. As with Dolby Digital 5.1,
detection and proper decoding of DTS 5.1 signals is automatic.
Note: DVDs with a DTS soundtrack almost always have it
configured as an option to the standard matrix Dolby Surround
format. To use DTS, you may have to go to the setup menus at
the beginning of the DVD and select "DTS 5.1" instead of "Dolby
Surround" or "Dolby Digital 5.1". In addition, many DVD players
have the DTS digital bitstream turned off by default and cannot
output a DTS soundtrack (even if selected on the disc's menu) until
you activate the player's DTS output. If you hear no sound the
first time you attempt to play a DTS disc, go to the DVD player's
configuration menus and turn on the DTS bitstream. This is a one-
time setting and need only be done once.

DTS Neo:6

This Rotel receiver features a second type of DTS surround sound
decoding: DTS Neo:6. This decoding system is similar to Dolby Pro
Logic II and is designed for playback of any 2-channel stereo recording,
either matrix-encoded or not. The Neo:6 decoder can be used with any
conventional 2-channel source such as a stereo TV or FM broadcast
or a CD. It can also be used as an alternative method of decoding
matrix-encoded Dolby Surround recordings or TV broadcasts. Activate
the DTS Neo:6 decoding with the DTS Neo:6 button as detailed later in
this section. DTS Neo:6 is not used with DTS 5.1 digital sources and the
button need not be pressed for those recordings.

Dolby Digital Surround EX

DTS-ES 6.1 and 7.1 Channel Surround
In 1999, the first Dolby Digital soundtrack was released to theaters with
an additional center back surround channel, intended to increase the
directional effects from behind the audience. This additional surround
channel is encoded into the two existing surround channels in Dolby
Digital 5.1, using a matrix encoding process similar to that used
previously in Dolby Surround. This new extended surround capability is
called Dolby Digital Surround EX.
DTS has added a similar capability for recording this extended surround
information called DTS-ES
®
further and developed the capability to record this extended surround
information as a discrete channel in a system called DTS-ES
Discrete.

6.1 Matrix. They have also taken it one step
6.1
®
All of these systems are extensions of the existing Dolby Digital 5.1
and DTS 5.1 digital surround sound formats. Users with one center
back speaker (a 6.1 configuration) or two center back speakers (a
7.1 configuration) can take advantage of this extended surround
information. On traditional 5.1 channel systems, Dolby Digital Surround
EX or DTS-ES 6.1 discs sound exactly the same as 5.1 channel discs in
each respective format.
If you have configured your system with one or two center back
speakers, decoding of DTS-ES discs is automatic, just as it is with
standard DTS soundtracks. Likewise, decoding of Dolby Digital Surround
EX discs is automatic with one exception. Some Surround EX titles do
not have the detection "flag" encoded on the disc. To activate the Dolby
Digital Surround EX features for these discs (or for standard 5.1 channel
Dolby Digital discs), you must manually activate Dolby Surround EX
processing.

Dolby Pro Logic IIx 6.1 and 7.1 Channel Surround

The latest technology from Dolby uses advanced matrix decoding for
the surround channels in a 6.1 channel or 7.1 channel system. Working
with any 2.0 channel or 5.1 channel recording, Dolby Pro Logic IIx
processing distributes the surround channel information among three
or four surround channels, with a Music mode optimized for musical
recordings and a Cinema mode optimized for film soundtracks.

Rotel XS6.1 and 7.1 Channel Surround

This receiver also features Rotel XS (eXtended Surround) processing
provides extended surround performance on 6.1 and 7.1 channel
systems. The key benefit of Rotel XS is that it works at all times with all
multichannel digital signals, even those that might not otherwise activate
Dolby Digital EX or DTS-ES surround decoding for the center back
channel(s). Always available when center back speaker(s) are configured
in the system setup, Rotel XS decodes the surround channels and
distributes the extended surround channels to the center back speaker(s)
in a way that tends to create a diffuse surround effect. Rotel XS works
with matrix-encoded surround signals (such as non-flagged DTS-ES and
Dolby Surround EX discs) as well as digital source material that is not
Dolby Surround EX encoded (such as DTS 5.1, Dolby Digital 5.1, and
even Dolby Pro Logic II decoded Dolby Digital 2.0 recordings).

Dolby Digital Plus

Built on Dolby Digital, the multichannel audio encoding standard for
DVD and HD broadcasts, Dolby Digital Plus was designed for the new
high-resolution delivery formats, but remains compatible with current
A/V receivers. It is supported by the HDMI digital connection standard.
Dolby Digital Plus can provide up to 7.1 channels with discrete channel
output at higher bitrates than Dolby Digital. Dolby Digital Plus is an
optional sound format for Blu-ray, and a mandatory inclusion for HD
DVD discs.
Dolby True HD
Dolby TrueHD is based on lossless coding technology to deliver studio
master-quality sound. Dolby TrueHD supports up to eight full-range
channels (the maximum allowed by Blu-Ray) of 24-bit/96 kHz audio.
Dolby TrueHD is supported by the HDMI v1.3 digital connection.
Additional features include Dialogue Normalization, which maintains
the same volume level when changing to other Dolby Digital and Dolby
TrueHD programming, and Dynamic Range Control (or 'Night Mode'),
reducing peak volume levels to allow late-night viewing of high-energy
surround sound without disturbing others. Dolby TrueHD is an optional
sound format for Blu-ray Disc, and a mandatory format for HD DVD.
