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.

Signature 2.0
Mono
When you are playing an older monaural recording or
movie and wish to listen to it in its pure state without
any enhancement or processing, select the Mono mode.
This mode will combine all audio channels and send
them to the center channel speaker only.
Applicable Mode Groups: The Mono mode is accessible
by pressing the
Music
mode group button until the
Mono
mode name appears in the
Information
Display
and on-screen status reports.
Stereo
The Stereo mode activates a Smart Stereo circuit to
calculate which type of stereo is best suited to the
current input source. Regardless of the input, pressing
the
Stereo
mode group button y will combine all
available input channels and funnel them into the front
left and right speakers only.
Smart Stereo is an intelligent agent that looks at the
input signal, and creates the stereo sound from Dolby
Digital, PCM Digital stereo or analog stereo without
any further intervention.
When an analog input is selected and the
Stereo
button y is pressed, the 2.0 turns off all digital signal
processing for the cleanest possible sound. This is a
unique feature of the 2.0, rarely found even in high-end
audio equipment.
Applicable Mode Groups: The Stereo mode is accessible
only by the
Stereo
button. Since Stereo is the only
mode available in this group, the
Stereo
button acts as
a toggle on/off selector. One press of the button will put
the 2.0 in the Stereo mode, and the next press returns
you to the previously selected mode.
Mono +
Playing a single-channel, monaural recording does not
mean that you have to sacrifice availability of surround
sound. The Mono + mode is NOT a single-channel
mode, but rather a specially designed surround mode
that takes incoming signals and creates a multichannel
audio presentation. Through the magic of the 2.0’s pro-
cessing circuits, one channel becomes five. If you wish
to play a selection in single-channel “true” mono, choose
the Mono mode, which may be accessed by pressing the
Music
mode group button y until the Mono mode
name appears in the front panel
Information Display
and the on-screen status messages.
The Mono + mode is only available when analog or
PCM Stereo input source is selected. Pressing the
Mono +
button when a Dolby Digital or DTS source
is playing selects the Digital Mono mode, a “true mono”
mode which is described above. Mono + is not available
when a Dolby Digital source is selected.
Applicable Mode Groups: The Mono + or Digital Mono
modes are accessible only by pressing the
Mono +
button. Since either is the only mode available in this
group, the
Mono +
button acts as a toggle on/off
selector. One press of the button will put the 2.0 in the
proper mono mode, and the next press returns you to
the previously selected mode.

The RDS Data System
The Signature 2.0’s RDS data system enables you to search for stations with specific program formats when an FM
station is transmitting the proper data. The following chart will help you to compare the abbreviations used in the
2.0’s display system to the actual names of each program type, or PTY.
NOTE: The assignment of a PTY code is done by the individual FM station. The 2.0 will accurately process the data
received, but it is up to the station to make certain that the code properly describes their programming.
