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 AVC-A11SR, 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 AVC-A11SR (see page 29)
lights before turning up the master 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 Extended Surround
DTS-ES Extended Surround 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 Extended
Surround 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 Extended Surround 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 Extended Surround includes two signal formats with different surround signal
recording methods, as described below.
TM
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.
TM
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.
When DTS-ES Discrete 6.1 or Matrix 6.1 encoded sources are decoded with a DTS-ES decoder, the
format is automatically detected upon decoding and the optimum playing mode is selected. However,
some Matrix 6.1 sources may be detected as having a 5.1-channel format, so the DTS-ES Matrix 6.1
mode must be set manually to play these sources. (For instructions on selecting the surround mode, see
page 30.)
The DTS-ES decoder includes another function, the DTS Neo:6 surround mode for 6.1-channel playback
of digital PCM and analog signal sources.
TM
2 DTS Neo:6 surround
This mode applies conventional 2-channel signals to the high precision digital matrix decoder used for
DTS-ES Matrix 6.1 to achieve 6.1-channel surround playback. High precision input signal detection and
matrix processing enable full band reproduction (frequency response of 20 Hz to 20 kHz or greater) for all
6.1 channels, and separation between the different channels is improved to the same level as that of a
digital discrete system.
DTS Neo:6 surround includes two modes for selecting the optimum decoding for the signal source.
• DTS Neo:6 Cinema
This mode is optimum for playing movies. Decoding is performed with emphasis on separation
performance to achieve the same atmosphere with 2-channel sources as with 6.1-channel sources.
This mode is effective for playing sources recorded in conventional surround formats as well, because
the in-phase component is assigned mainly to the center channel (C) and the reversed phase
component to the surround (SL, SR and SB channels).
• DTS Neo:6 Music
This mode is suited mainly for playing music. The front channel (FL and FR) signals bypass the decoder
and are played directly so there is no loss of sound quality, and the effect of the surround signals output
from the center (C) and surround (SL, SR and SB) channels add a natural sense of expansion to the
sound field.
