Introduction
to the CP-3
Lexicon
The Ambience and Reverberation modes transform the listening room into
a new acoustic space, letting you choose an environment which matches
your music or your mood. Unlike most ambience processors, the CP-3
provides full stereo processing, preserving the critical SI information in the
recording and expanding upon it. The Ambience mode generates the side
and rear reflection patterns of idealized rooms and concert halls. The larger
spaces add the true depth and realism of a concert hall to classical and
popular music, while the smaller spaces are ideal for jazz and rock. The
Reverberation mode is similar, but places more emphasis on rich, dense
reverberant decay than on early reflections. It is especially good for simu-
lating large, highly reverberant spaces such as churches, stadiums, and
cathedrals.
The requirements for processing sound for home theater are quite different
than those for music. Lexicon invented the technology that permits the most
accurate reproduction of film sound in the same system that is used for
music listening, and the software-based CP-3 is optimized for each of these
unique tasks. The Music Surround mode is specifically designed to opti-
mally play conventional stereo music through any system which includes
side or side-located rear speakers. Additionally, the CP-3 is able to perform
automatic analysis and error correction to compensate for problems in the
source material.
For films encoded with Dolby Surround, Lexicon has incorporated the
Lucasfilm Home THX Cinema processing into the CP-3. This utilizes a
patented, completely digital Dolby Pro Logic Surround decoder, and is the
only one with automatic correction of inter-channel phase and channel-
balance errors (the most common audio problems in currently available
video releases of films).
The CP-3 also provides modes for expanding monaural film sound tracks
(Mono Logic), general TV viewing (Television) and, of course, direct two-
channel stereo playback (Effects Mute ON).
