Installation Worksheet
The DC-2 can be thought of as four units in one. At its heart is a referencequality 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, 24-bit Digital-to-Analog converter that rivals the most exotic and costly stand-alone devices. To harness
all of this digital audio power, the DC-2 also includes a built-in line-level
preamplifier with 8 analog audio inputs and 8 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-2 includes a high-quality composite and S-video switcher. The DC-2
also includes provisions for adding a digital output, and a second RS-232
port as well as three expansion ports for future enhancements. The back
panel includes a bare wire block terminal for trigger outputs for easy
connection to associated equipment.
The DC-2 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 automation systems.
Three versions of the DC-2 are available: THX, Dolby Digital, and DTS. The
unit is internally-configurable so upgrades can be progressively added to
include all the features of the DTS version.
Introduction
All versions of the DC-2 include NIGHTCLUB, CONCERT HALL, CHURCH,
and CATHEDRAL effects for creating an ideal custom listening environment as well as MUSIC LOGIC and MUSIC SURROUND which offer
ambience extraction. 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-2,
transporting you more deeply into the performance.
The DC-2 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-2 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-2 for listening to 5.1 channel
music or music videos.
Lexicon
The DC-2 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-2 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. These enhancements ensure that film soundtracks, which
are typically mixed for the acoustics of large theaters, sound as the filmmakers intended when played back in the relatively small environment of a
home theater.
Using the
Documentation
Glossary of Terms
Because the DC-2 is designed to be customized for your system and your
listening space, the information required for installation is extensive.
The Owner's Manual is designed to assist you in installing, calibrating and
operating the DC-2. It should be used in conjunction with the remote control
when configuring the system to perform optimally in your environment.
This manual was written with the underlying assumption that the installer
is familiar with audio/video system installation. An Installation
Worksheet is provided at the end of this manual for documentation of the
settings arrived at during the calibration procedure.
Although the DC-2 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 DC-2.
AC-3 FX The term AC-3 FX (Dolby Digital Effects) is used to describe all of
the effects which are compatible with Dolby Digital input signals. Any AC3-capable software and/or source components should be labeled with a
badge, similar to the one on the DC-2 front panel (AC-3 and DTS versions).
DTS FX The term DTS FX (Digital Surround Effects) is used to describe all
of the effects which are compatible with DTS Digital Surround input
signals. Any DTS-capable software and/or source components should be
labeled with a badge, similar to the one on the DC-2 front panel (AC-3 and
DTS versions).
Downmix describes the process of creating a two-channel output from a
multichannel (>2) signal. Downmixing is necessary to maintain compatibility between multichannel formats and devices such as Dolby Digital and
DTS, and two-channel formats and devices, such as stereo tape decks and
VCRs.
Effect An effect is a configuration that determines how the DC-2 will process
an input signal. The DC-2 can contain as many as 24 effects: Panorama,
Nightclub, Concert Hall, Church, Cathedral, Party, 2-Channel, Music Surround,
Music Logic, Logic 7, TV Matrix, Pro Logic, THX Cinema, Mono Logic, 5.1 2Channel, 5.1 Music, 5.1 Logic 7, Dolby Digital, THX 5.1, DTS 2-Channel, DTS
Music, DTS Logic 7, DTS Film and DTS THX 5.1.
Parameter Each Effect has a set of parameters (controls) that characterize it.
Parameter settings can be changed to customize each Effect for your room
and listening taste.
Effect Parameter values are stored/recalled with each Effect. Some examples
are: Subwoofer Level and Vocal Enhance
System parameter values are not associated with a particular Effect and their
values do not change when a new Effect is loaded. An example is: Speaker
Configuration.
PCM FX The term PCM FX (Pulse Code Modulation Effects) is used to
describe all of the effects which are compatible with two-channel input
signals (analog or digital).
Two-Channel We use the term two-channel rather than "stereo" because a
two-channel input can contain monaural, stereo or matrix-encoded stereo
sound depending on how it was mixed.

Considerations
The DC-2 is a highly specialized signal processing computer and requires
special care during installation to ensure optimum performance.
The DC-2 may be installed on a shelf or in a standard 19" equipment rack,
using an optional rack-mount kit available from Lexicon dealers. Observe
the following precautions:
• Select a dry, well-ventilated location out of direct sunlight.
• Do not stack the DC-2 directly above heat-producing equipment such as
power amplifiers.
• Avoid placing the DC-2 near unshielded TV or FM antennas, cable TV
decoders, or other receivers. The DC-2 may interfere with some FM
tuners if it is placed immediately above or below them. Some products,
particularly power amplifiers, may cause hum if they are in close
proximity.
• Make sure the DC-2 front panel IR receiver window is unobstructed. The
remote control must be in line-of-sight to this receiver for proper
operation. If line-of-sight is impractical, an infrared remote repeater can
be used with the rear panel IR connector. The DC-2 may be placed in a
glass-doored cabinet but smoked glass will make the front panel Liquid
Crystal Display (LCD) difficult to read and will reduce the sensitivity of
the IR receiver.
AC Connections
6
The DC-2 is designed to be connected to an uninterrupted AC power line in
the same manner as a VCR or a television. We recommend the use of an AC
line filter to protect against line surges, or the installation of a line conditioner to protect against under voltage (brownouts) as well as overvoltage
conditions.
The DC-2 has a master power switch on the rear panel above the IEC
standard AC power receptacle. This switch may be left ON continuously
when the unit is in regular use. When the DC-2 will not be used for an
extended period of time, or whenever you are connecting or disconnecting
any cables to the unit, this switch should be turned OFF.
Connect the power cable to the DC-2, then plug the power cord into a wall
outlet or into an unswitched outlet on a surge protector. Be sure that the
power cord is firmly seated in the connector on the rear panel of the DC-2.
DC-2 Digital Controller
Installation
Wiring Considerations
There is debate over the audible effects of different types of interconnects.
Good engineering practices have minimized the effect that cables might
have on the inputs and outputs of the DC-2 — but feel free to evaluate
different interconnects in your system. Be conscious, however, of the
mechanical stress from repeated insertion and overly tight connectors, and
the possibly corrosive nature of some contact-enhancing fluids.
Note that the use of standard audio cables for video or digital audio
applications may cause signal degradation, and is not recommended. For
these connections, please use only cables that are designed for the application — these have different impedance characteristics than cables designed
for analog audio applications. Consult your dealer for recommendations.
All cables should be kept as short as possible.
In general, speaker cables should be kept short, and low-impedance wire
should be used throughout to assure efficient power transmission and
avoid audible distortion. Recommended wire lengths are given in the table
below. Although these examples can be used as a general guide, your
system manuals should provide detailed information specific to your
components.
Audio/Video Cables
Speaker Connections
Wire Lengths
Length AWG Size
up to 12 feet 16 gauge
up to 18 feet 14 gauge
up to 29 feet 12 gauge
up to 51 feet 10 gauge
Before making any connections, turn off ALL audio and video components,
including individual power amplifiers. (Unplug any preamps and power
amps that don’t have power switches.)
The DC-2 is designed to function as the control center of the system,
selecting inputs and controlling the volume of all speakers in the system.
The following diagram shows a system with a tape deck, an AM/FM tuner,
a CD player with a coaxial digital audio output, a satellite receiver with an
optical digital output, a DVD player and a VHS VCR. This example shows
the tape deck and VCR set up for recording and dual-zone audio.
Actual system connections will vary widely depending on the components
used. Consult your dealer for details on your particular requirements.

Input sources should be connected directly to the DC-2 inputs. Since TAPE,
TUNER and CD are audio only, the video output will default to the video
signal from VCR. This allows TV or other video source viewing while
different audio is playing, but can be changed in the INPUT CONFIG menu.
Connect your main stereo amplifier to the DC-2 FRONT outputs. Connect
any additional amplifiers to the remaining outputs on the DC-2: side
amplifiers to the SIDE outputs, rear amplifiers to the REAR outputs, centerchannel amplifier to the CENTER output and the subwoofer amp to the
SUBWOOFER output. If you are using THX-type di-pole surround speakers, the amplifier driving them should be connected to the DC-2 SIDE
outputs.
Whenever possible, connect both analog and digital outputs of digital
sources. This enables use of a digital input for the main zone, and the
corresponding analog input for the Record/Zone 2 outputs.
Note the use of Y-connectors to feed the DC-2 Record output to both the
VCR and the tape deck.
8
DC-2 Digital Controller
Installation
The DC-2 has five composite and S-Video inputs. Connection to an S-Video
input will override the composite signal connected via the RCA-type
connector. Note that an S-Video input will be output on both the composite
and S-Video outputs. Composite input signals will not be output as S-Video.
You can assign any video source to any (or all) of the eight DC-2 inputs via
the Input Configuration submenu of the Setup menu. This can be very
useful in systems which use a VCR as the tuner for TV viewing, as the video
feed from the VCR can be assigned to both the VCR and TV inputs. The
VCR's audio signals can be fed to both inputs with Y-connectors. (Do not use
Y-connectors on video signals.) This allows the audio and video signals
from the VCR to be used for both TV and VCR viewing.
You can also assign any video source to audio-only sources such as an AM/
FM tuner, to enjoy music from another source while viewing a video source.
It is important to remember that the impedance characteristics of composite
video and digital audio are different from analog audio. You should only
use cables specifically designed for video and digital audio. Consult your
dealer for recommendations.
The DC-2 has eight digital audio inputs: five coax via RCA and three optical
via TOSLINK™. The digital inputs can be set up to be selected with any (or
all) of the eight inputs via the Input Configuration menu. Using the digital
inputs will always provide superior performance.
Video Connections
Digital Audio Connections
Note that "AC-3 ready" laser disc and LD/DVD players output Dolby
Digital (AC-3) data from laser discs on a separate RCA jack in Radio
Frequency (RF) form. To maintain the exceptional performance of the DC2, an outboard demodulator is required to turn this RF signal back into a
digital bitstream. By performing the necessary demodulation outside the
DC-2, the potential for RF interference is eliminated. The Lexicon LDD-1 is
an excellent example of one such device.
