same mode is used whenever source is selected. See page

an input source.

To make it easy to select a mode, they are divided into
two groups, “Movies” and “Music,” although some modes
are used with both types of program content. In addition,
there is a Mono + mode and a pure Stereo mode available.
The following definitions of the various modes is
presented to give you a better idea of where each should
be used, and which type of sources it is compatible with.

Dolby Pro Logic
Dolby Pro Logic is the home version of the system
originally developed to deliver four channels of surround
information within the left and right channels of a motion
picture. Dolby Pro Logic uses special encoding techniques
to provide a center channel, used mostly for dialog, and a
surround channel, used mostly for effects, in addition to
the left and right front channels. It is important to
remember that in Pro Logic, the feed to the surround
channels is a monaural one, with the same bandwidth-
limited signal going to both the left and right surround
channels.

Although Pro Logic is mostly associated with movies,
it is also used to enhance an increasing number of tele-
vision programs, ranging from sports broadcasts to action
programs such as Xena, Warrior Princess, sci-fi programs
such as Babylon Five, Deep Space Nine and Star Trek, and
dramatic programs such as Law & Order. Variety and
concert programs also benefit from surround encoding.
A complete list of programs broadcast with Dolby
Surround encoding may be found at the Dolby Labs
web site at www.Dolby.com.

Once a program is encoded with surround information,
such as in a theatrical movie, the surround matrix
stays with the program as long as the stereo tracks are
properly broadcast. Thus, the surround information
follows a movie from the theaters to video cassette (HiFi-
Video only) and disc release, on cable, satellite or pay-per-
view, and via traditional broadcasting. This enables you to
enjoy the surround information almost any time the
movie is available, not just from prerecorded playback.

The Dolby Pro Logic system is used to decode any four-
channel matrix-encoded source, no matter how it is
delivered. For that reason, if a film is originally recorded
with a left/center/right/surround soundtrack, it will
require Dolby Pro Logic even when the movie is delivered
with a Dolby Digital soundtrack. That is why some DVD
discs, even though they utilize Dolby Digital, still require
Dolby Pro Logic decoding, though it is done in the digital
processor.

Dolby Pro Logic is also appropriate when listening to

also wish to experiment with Pro Logic on standard two-
channel stereo recordings. Although it is not intentional,
many recordings contain ambient information that
produce a pleasing surround effect when used with Pro

Dolby Digital
Dolby Digital is a major improvement over Dolby
Pro Logic in that it delivers up to five surround channels
along with a special, dedicated Low-Frequency Effects
(LFE) channel for bass information. Unlike the bandwith
limited, monaural surround of Dolby Pro Logic, Dolby
Digital features two discrete, full-bandwidth surround
channels in comparison to Pro Logic’s single, bandwidth-
limited, mono-surround channel. All channels are digital,
with high signal-to-noise ratios and wide dynamic range.
With Dolby Digital you are now able to have an exact re-
creation of the theatrical sound experience in a
home environment.

The digital data stream that delivers the Dolby Digital
information may be sent to the 2.0 via either electrical
connection using coax cables, or optically, using fiber
connections. DVD and possibly other futural sources will
take advantage of Dolby Digital. The first consumer
implementation of Dolby Digital, laser discs, used the
intermediary step of converting the digital information to
an RF modulated signal so that it would fit within the
capacity of the LV format. Since the Signature Series 2.0
does not accept RF signals, an optional outboard RF-to-
data demodulator is required for use with laser disc
players.

Applicable Mode Groups: Also known as AC-3, as it is
the third version of Dolby Laboratory’s Audio Coding
system for digital audio, Dolby Digital will initially be
used most often with movies, but it is also available
in the Music mode grouping, for applications where
musical programs are recorded in Dolby Digital. Note that
the mode is the same in both groups, but it is presented
twice for your convenience.

Dolby Digital Late Night
The “Late Night” mode is a special version of Dolby
Digital which enables you to experience the same discrete
full-bandwidth, multichannel audio as the standard Dolby
Digital mode, but it is designed to reduce peak levels by
1⁄4 to 1⁄3 of normal. This prevents abruptly loud audio
transition such as explosions or symphonic crescendos
from causing disturbance to others in the household
without reducing the impact or quality of the remaining
digital signal.

Movie and Music Modes
The 2.0’s digital audio processing system provides a
number of alternative modes that may be used when
listening to movies or Music 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, the
recording 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.
