[2] DTS Digital Surround

Digital Theater 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, 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.

2 DTS compatible media and playback methods

Symbols indicating DTS compatibility: and

The following are general examples. Also refer to the player’s

operating instructions.

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 “hissing” 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-1306, 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-1306

( page 23) 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 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. Changes in the

sound quality are reduced by decoding with emphasis on the

front channel signals (FL and FR), and a natural sense of

expansion is given to the sound field by the effect of the

surround signals output from the center (C) and surround (SL,

SR and SB) channels.
