Lexicon Lexicon Part #070-13234 owner manual Introduction

The DC-1 can be thought of as four units in one. At its heart is a reference-	Introduction
quality 8-channel music and film digital audio computer capable of creating
or recreating a limitless amount of listening environments. This digital
audio computer is mated to an 8-channel Digital-to-Analog converter that
rivals the most exotic and costly stand-alone devices. To harness all of this
digital audio power, the DC-1 also includes a built-in line-level preamplifier
with 8 analog audio inputs and 4 digital audio inputs for easy integration
with multiple source components. Since many of these source components
are also capable of outputting high quality video signals, the DC-1 includes
a high-quality composite and S-video switcher. The back panel includes a
DIN terminal (PWR CTL) for trigger outputs for connection to associated
equipment.
The DC-1 is designed to satisfy the most rigorous demands, while retaining
simplicity for casual use as well. Using the system can be as simple as
pressing an input key and turning the volume up and down. Less-used
functions are organized into a simple on-screen menu system and “hidden”
buttons on the remote control. Controls are provided to accommodate
virtually any system configuration and to allow for varying recording,
mixing, and transmission styles, as well as for system control from a second
zone, and for control by sophisticated infra red control systems.
For software Versions 3 and 4, two versions of the DC-1 are available: Dolby
Digital, and DTS. Both versions include THX enhancements. The unit is
internally-configurable to allow upgrading to the complete DTS version.
Both versions offer ambience generation effects such as CATHEDRAL, and
ambience extraction effects such as MUSIC LOGIC for customizing your
listening environment. As these programs use the same Lexicon technology
used by the overwhelming majority of professionals for adding ambience
to their recordings, you will find playback greatly enhanced by the DC-1,
transporting you more deeply into the performance.
The DC-1 also recreates 5.1 channel soundtracks with stunning accuracy,
and takes them to a new level of realism with Lexicon’s proprietary
Logic 7 technology. These effects allow you to expand 5.1 channel as well as
two channel soundtracks for 7.1 and virtual 7.1 channel playback for an
increased sense of spaciousness and envelopment.
The AC-3 and DTS versions of the DC-1 provide separate effects for
listening to 5.1 channel music and down-mixing 5.1 channels to two
channels, allowing you to fine-tune the DC-1 for listening to 5.1 channel
music or music videos.
The DC-1 can be easily integrated with the various types of loudspeaker
systems currently available, including those that are THX certified. By
adhering to the rigorous THX Ultra specification, the DC-1 includes THX
enhancements for optimizing playback of matrix-encoded film soundtracks
as well as Surround EX for those recorded in the Dolby Digital and DTS
discrete formats.
