Introduction to the DC-1

Lexicon

System Overview Although the DC-1 performs very complex signal processing, a great deal of effort has gone into making the technology behind the effects as transpar- ent 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 DC-1.

Glossary of Terms

Effect An effect is a configuration that determines how the DC-1 will process an input signal. The base unit contains 11 effects: Pro Logic, TV Matrix, Mono Logic, Panorama, Nightclub, Concert Hall, Church, Cathedral, Music Logic, Party and Two Channel. The THX version of the DC-1 contains these effects as well asMusic Surround, THX Cinema and Logic 7. The Dolby Digital version contains all of the above effects as well as 5.1 Music, Dolby Digital, THX 5.1, 5.1 Logic 7 and 5.1 Two Channel.

Parameter Each Effect has a set of parameters (controls) that uniquely characterize it. The settings of the parameters can be changed to custom- ize each Effect.

Effect Parameter values are stored/recalled with each Effect. Some ex- amples are: Rolloff, Subwoofer Level, etc.

System parameter values are not associated with a particular Effect and their values do not change when a new Effect is loaded. Examples are: display contrast, volume, etc.

Presets The DC-1 contains a set of Effects with factory-set parameters. You can use these Effects as is, or make changes to the parameters to suit your own needs. The factory parameter settings are permanently stored in memory where they can be accessed for comparison with your own versions, or restored.

Essentially, the DC-1 can be thought of as a line level preamp D/A converter with three audio-only, five audio/video, and four digital inputs. It behaves as the master processor for your system, controlling system volume, bal- ance, source selections, output selections for audio and video, and acousti- cal environments specifically designed for music and movies.

The remote control provided with the DC-1 is designed for simple daily use, as well as for use in configuring the DC-1 to work optimally with your system. The remote gives you access to setup controls and parameter menus for all of the DC-1 Effects.

In many systems, a learning remote such as the Lexicon 500T may take the place of the DC-1 remote. If you are using one of these, we strongly suggest that the types of operating controls we have provided be adapted into the universal remote. We have found these controls enhance the listening/ viewing experience while keeping the technology transparent.
