Introduction Introduction to the CP-3 1 to the CP-3 CP-3 Digital Surround Processor Introduction All of the operating modes of the Lexicon CP-3 Digital Surround Processor have a common goal: to draw you, the listener, more deeply into a musical performance or a film. For music the CP-3 uses true stereo digital processing to recreate the original recording space or to create a new one of your ® choosing. For films it offers an extremely accurate version of Dolby Pro Logic Surround decoding with a

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 re

Introduction to the CP-3 Lexicon System Overview Although the CP-3 performs very complex signal processing, a great deal of effort has gone into making the technology behind the effects as transparent as possible to the user. To understand the overall organization of the unit, it is helpful to define those few terms which are unique to the CP-3. Glossary of Terms Mode A mode is a configuration that determines how the CP-3 will process an input signal. The CP-3 contains four basic modes: Panorama

Introduction to the CP-3 CP-3 Digital Surround Processor Essentially, the CP-3 can be thought of as a line level preamp with one audio-only and three audio/video inputs. It behaves as the master proces- sor for your system, controlling system volume, balance, source selections and acoustical environments. Two remote control units are provided with the system: an Expanded remote, and a Standard remote. The Expanded remote is designed primar- ily for use in configuring the CP-3 to work optimally w

(Unplug any preamps and power amps that don’t have power switches.) The CP-3 is designed to function as the control center of the system, selecting inputs and controlling the volume of all speakers in the system.

A typical system might use Input 1 for CP-3 as a preamp television, Input 2 for VCR, Input 3 for video disc and Input 4 for CD player or turntable (output through a preamp). Since Input 4 is audio only, the video output will default to the video signal from Input 1. This feature allows TV or other video source viewing while

Connection Lexicon Connecting the CP-3 If you have a receiver with no external access to the preamplifier outputs, you can use a tape output or external processor loop to the CP-3. However, in a Tape Monitor Loop any change in the receiver’s volume control after the system is adjusted will upset the balance between the main and auxiliary speakers. * In this configuration, use a Y-connector to hook the VCR to Video 1 as well if its tuner is used instead of the TV tuner. ** In this configuration,
