Signature 2.0

DTS

DTS is a digital audio delivery system used by both

audio-only labels as well as an optional, alternative

digital sound system for DVD and LD. DTS delivers

high-quality, discrete 5.1 audio using a digital delivery

system that is similar in concept to Dolby Digital, but

with different bit rates and encoding algorithms.

The physical connection for DTS playback is identical to

the connections used for Dolby Digital, in that either coax

or optical connections are made to the source player. The

main difference between the two systems with regard to

hook-ups is that when DTS audio tracks are present on a

laser disc, they are played back as standard PCM audio

streams, and thus no RF demodulator is required. If you

own a laser player and plan to play back DTS discs, make

certain that a connection is made from the optical or coax

output of your LD player to one of the 2.0’s digital inputs.

Using the Input Assignment options in the Source

Configuration menus described on page 28 it is possible

to take advantage of the 2.0’s flexibility to assign the

same video output to both the analog and digital decoding

sections of the 2.0.

It is worth noting the DTS has also issued a library of

audio-only discs that may be played back using any CD

player that features a digital output. To take advantage of

these discs, make certain there is a connection between

the digital audio output of your CD player and one of

the digital inputs of the 2.0.

Programs encoded with DTS always have a native 5.1

channel mode, but depending on the configuration of your

specific system you may not always want to play a pro-

gram back in the 5.1 channel mode. For that reason, the

2.0 provides not only the pure DTS 5.1 mode, but also

provides the capability to decode the DTS data streams,

but down mix the incoming signal so that it is sent to

the front left and right speakers only (DTS 2 Chan)

or to the front left and right channels and left and right

surround channels. The center channel is downmixed

into the front left and right channels (DTS 2 Chan).

Applicable Mode Groups: As DTS is used for both audio-

only discs as well as movies and other video-related

programs, all DTS modes are available in both the Music

and Movies mode groups. Note that when a DTS 5.1

program is playing and you press the

Stereo

button y,

the 2.0 will indicate DTS 2 Chan.

NOTE: Due to the way in which DTS operates, there

is no data available when the

Display

button x is

pressed while a DTS source is playing.

Movie Modes

The 2.0’s digital audio processing system provides a

number of alternative modes that may be used when

listening to movies via an analog input source. For

movies, a series of four different modes is available

that use the basic matrix decoding to extract center

and surround channels from two-channel audio, similar

to Pro Logic. The Movie modes, however, vary from

Pro Logic in that they add additional blending of the

channels to offer different simulations.

Each of the four Movie modes is slightly different, and

the best way to find if one of them suits your taste and

the specific acoustic conditions of your listening room is

to try them all, using Dolby Pro Logic as a baseline for

comparison. Nothing will be “hurt” or damaged by trying

the different modes.

Applicable Mode Groups: The Movie modes are available

only in the Movie mode group, and only when an analog

source is being played.

NOTE: The Movie and Music modes are available

only when an analog or PCM digital source is playing.

If you attempt to select one of these modes when a

Dolby Digital or DTS source is playing, the front panel

Information Display

will flash to remind you of the

mismatch. At the same time, the 2.0 will automatically

select an appropriate mode. The suggested mode may

be identified by pressing the

Display

button x and

viewing the on-screen display.
