Digital TheateE Surround (also called simply DTS) is a mult-channel digiLal signal format developed by Digtal
TheateE Systems
DTS offers the same "51 " playback channels as Dolby Digital (front left, front right and cente{, surround left and
surround right) as well as the stereo 2-channel mode The signals for the d fferent 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 DTB playback is used n movie theaters, a separate CD-ROM synchronized with the fire s 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 dscs can be handled n the same way as discs with other formats •
TheEe are also musc CDs recorded in DTS These CDs include 51-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 requi_ed)
DTS surround track playback offers the same intricate, grand sound as in a movie theateE, right in your own
listening room

1 DTS signals are recorded n the same way on CDs and LDs as PCM sg_lalS Because of this, the un-
decoded DTS signals are output as random "hissy" nose 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 T_ avoid this, be sure to switch the nput mode to "AUTO" or "DTS" before playing CDs or LDs
recorded n 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 compat ble 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 sor_ of internal signal
processing (output level adjustment, sampling frequency conversion, etcl In this case the DTS-encoded
signals may be processed erroneousl% in which case they cannot be decoded by the AVR-3802, 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-3802 (see page 29)
lights before turning up the master volume
3 A DVD player with DTB-compatible digital output is required to play DTS DVDs A DTS D gital Output logo

DTS-ES Exte_lded Surround is a new multi-channel digital signal format developed by Digital Theater Systems
Inc While offering high compatibility with the conventional DTB Digtal Surround format, DTS-ES Extended
Surround greatly improves the 360-degree surround impress on and space expression thanks to further expanded
surround signals This format has been used professionally in movie theaters since 1999
In addition to the 51 surround channels (EL, FR, C, SL, BR and LEE}, 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 61 channels DTS-ES Extended Surround includes two signal formats with different surround signal recording
methods, as described below
DTS-E$ TM Discrete 6.1
DTS-ESTM Discrete 61 is the newest recording format With it, all 61 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 BB 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
surround ng the listener from 360 degrees
Though maximum performance is achieved when sound tracks recorded with this system are played using
a DTS-ES decodeE, when played with a conventional DTS decodeE the SB channel signals are automatically
down-mixed to the BL and SR channels, so none of the signal components are lost
DTS-ES TM Matrix 6,1
With this format, the additional SB channel signals undergo matrix encod ng and are input to the SL and SR
channels beforehand Upon playback they are decoded to the 9L, SR and SB channels The performance
of the encoder used at the time of recording can be fully matched using a high precision digtal matNx
decoder developed by DTB, thereby achieving surround sound more faithful to the producer's sound design
aims than with conventional 51- or 61-channel systems
In addition, the bit stream format is 100% compatible with conventional DTS signals, so the effect of the
Matrix 61 format can be achieved even with 5 l-channel signal sources Of course it is also possible to play
DTS-ES Matrix 61 encoded sources with a DTS 51-channel decoder
When DTS-ES Discrete 61 or Matrix 61 encoded sources are decoded with a DTS-ES decoder, the format
is automatically detected upon1decoding and the optimum playing mode is selected However, some Matrix
61 sources may be detected as having a 51-channel format, so the DTS-ES Matrix 61 mode must be set
manuaNy to play these sources
(For i_lStructions o_1selecting the surround mode, see page 30)
The DTS-ES decoder ncludes another function, the DTB Neo:6 surrou_ld mode for 61-cha_1nel playback of
digital PCM and analog signal sources
DTS Neo:6 TMsurround
This mode applies conventional 2-channel signals to the high precision digital matrix decoder used for DTS-
ES Matrix 61 to achieve 6 t-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 61
channels, and separation between the different channels is improved to the same level as that of a digital
d screte system
DTS Neo:6 surround includes two modes for select ng the opt mum decoding for the signal source
• DTS Neo:6Cinema
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 61-channel sources
This mode is effective for playing sources recorded in conventional surround formats as well, because the
imphase 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 musc The front channel (FL a_ld ER) signals bypass the decoder
and are played directly so there s _1oloss of sound quality, and the effect of the surround signals output
from the ce_lter (C) and surround {SL, SR and SB) cha_lnels add a natural se_lse of expa_lsion to the sound
