The charts and graphs in this section provide additional
details that will assist you in the selection of the Surround
mode, the use of the RDS data system and adjustment of
the Bass Boost and Treble Cut controls.

For your convenience, a surround mode may be per-
manently attached to each input source profile, so that the
same mode is used whenever source is selected. See page
23 for instructions on linking a surround mode to 
an input source.

Alternatively, you may change surround modes at any
time by pressing one of the 

y

on the remote, or by pressing the front panel

.

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 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 your best choice when listening to 
a movie or television program through an analog input.
When Dolby Pro Logic is required by a digital input, the
2.0 will automatically select it for you.

Dolby Pro Logic is also appropriate when listening to
music programming when the packaging shows a “Dolby
System,” “Dolby Stereo” or other surround logo. You may
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
Logic.
