[2] DTS Digital Surround
DTS Digital Surround (also called simply DTS) is a multi-
channel digital signal format developed by Digital Theater
Systems.
DTS offers the same "5.1" playback channels as Dolby
Digital (front left, front right and center, surround left and
surround right) as well as the stereo 2-channel mode. The
signals for the different channels are fully independent,
eliminating the risk of deterioration of sound quality due to
interference between signals, crosstalk, etc.
DTS features a relatively higher bit rate as compared to
Dolby Digital (1234 kbps for CDs and LDs, 1536 kbps for
DVDs) so it operates with a relatively low compression rate.
Because of this the amount of data is great, and when DTS
playback is used in movie theaters, a separate CD-ROM
synchronized with the film is played.
With LDs and DVDs, there is of course no need for an extra
disc; the pictures and sound can be recorded simultaneously
on the same disc, so the discs can be handled in the same
way as discs with other formats.
There are also music CDs recorded in DTS. These CDs
include 5.1-channel surround signals (compared to two
channels on current CDs). They do not include picture data,
but they offer surround playback on CD players that are
equipped with digital outputs (PCM type digital output
required).
DTS surround track playback offers the same intricate, grand
sound as in a movie theater, right in your own listening
room.

1: DTS signals are recorded in the same way on CDs and
LDs as PCM signals. Because of this, the un-decoded DTS
signals are output as random "hissy" noise from the CD
or LD player's analog outputs. If this noise is played with
the amplifier set at a very high volume, it may possibly
cause damage to the speakers. To avoid this, be sure to
switch the input mode to "AUTO" or "DTS" before
playing CDs or LDs recorded in DTS. Also, never switch
the input mode to "ANALOG" or "PCM" during playback.
The same holds true when playing CDs or LDs on a DVD
player or LD/DVD compatible player. For DVDs, the DTS
signals are recorded in a special way so this problem does
not occur.
2: The signals provided at the digital outputs of a CD or LD
player may undergo some sort of internal signal
processing (output level adjustment, sampling frequency
conversion, etc.). In this case the DTS-encoded signals
may be processed erroneously, in which case they cannot
be decoded by the AVR-3806, or may only produce noise.
Before playing DTS signals for the first time, turn down
the master volume to a low level, start playing the DTS
disc, then check whether the DTS indicator on the AVR-
3806 (
volume.
3: A DVD player with DTS-compatible digital output is
required to play DTS DVDs. A DTS Digital Output logo is
featured on the front panel of compatible DVD players.
Recent DENON DVD player models feature DTS-
compatible digital output – consult the player's owner's
manual for information on configuring the digital output for
DTS playback of DTS-encoded DVDs.

[3]DTS-ES
DTS-ES is a new multi-channel digital signal format developed by
Digital Theater Systems, Inc. While offering high compatibility
with the conventional DTS Digital Surround format, DTS-ES
greatly improves the 360-degree surround impression and space
expression thanks to further expanded surround signals. This
format has been used professionally in movie theaters since
1999.
In addition to the 5.1 surround channels (FL, FR, C, SL, SR and
LFE), DTS-ES also offers the SB (Surround Back, sometimes
also referred to as "surround center") channel for surround
playback with a total of 6.1 channels. DTS-ES includes two
signal formats with different surround signal recording methods,
as described below.
2 DTS-ES™ Discrete 6.1
DTS-ES Discrete 6.1 is the newest recording format. With it, all
6.1 channels (including the SB channel) are recorded
independently using a digital discrete system. The main feature
of this format is that because the SL, SR and SB channels are
fully independent, the sound can be designed with total freedom
and it is possible to achieve a sense that the acoustic images are
moving about freely among the background sounds surrounding
the listener from 360 degrees.
Though maximum performance is achieved when sound tracks
recorded with this system are played using a DTS-ES decoder,
when played with a conventional DTS decoder the SB channel
signals are automatically down-mixed to the SL and SR
channels, so none of the signal components are lost.
2 DTS-ES™ Matrix 6.1
With this format, the additional SB channel signals undergo
matrix encoding and are input to the SL and SR channels
beforehand. Upon playback they are decoded to the SL, SR and
SB channels. The performance of the encoder used at the time
of recording can be fully matched using a high precision digital
matrix decoder developed by DTS, thereby achieving surround
sound more faithful to the producer's sound design aims than
with conventional 5.1- or 6.1-channel systems.
In addition, the bit stream format is 100% compatible with
conventional DTS signals, so the effect of the Matrix 6.1 format
can be achieved even with 5.1-channel signal sources. Of course
it is also possible to play DTS-ES Matrix 6.1 encoded sources
with a DTS 5.1-channel decoder.
