Thank you for your purchase of this upgrade for your DC-1. This Owner's
Manual Addendum is designed to provide supplementary information for
systems with Dolby Digital® AC-3 Version 2.00 or DTS® software installed.
About Dolby Digital AC-3 Encoding
Because multichannel recordings are made up of so much information, new
ways of storing and transmitting data have been created. Dolby Laboratories developed AC-3, a digital audio coding technique on which the Dolby
Digital surround format is based.
On a typical compact disc, 16-bit samples are taken 44,100 times per second
for each channel. This allows as much as 74 minutes of 2-channel audio on
a single CD. However, if a digital recording consists of six channels, up to
two hours in length, storage or transmission becomes impractical due to the
immense amount of data. Therefore, new forms of digital audio coding
(sometimes referred to as "perceptual coding") have been developed to
allow the use of lower data rates with a minimum of perceived degradation
of sound quality.
Designed specifically to handle multichannel audio, AC-3 takes advantage
of a psychoacoustic phenomenon known as auditory masking. It divides
the audio spectrum of each channel into narrow frequency bands of
different sizes optimized with respect to the frequency selectivity of human
hearing. This makes it possible to sharply filter coding noise so that it is
forced to stay very close in frequency to the frequency components of the
audio signal being coded. By reducing or eliminating coding noise wherever there are no audio signals to mask it, the sound qulity of the original
signal can be subjectively preserved. The result is multichannel sound that
is subjectively equal to 2-channel digital recordings, which can be stored
and transmitted efficiently.
Introduction
About DTS Encoding
DTS Digital Surround is a format that utilizes an encode/decode system to
deliver up to six discrete channels of high quality digital audio. Like the
Dolby Digital format, DTS Digital Surround is often referred to as a 5.1
channel format because it is capable of 5 full range channels in addition to
a limited range Low Frequency Effect channel (LFE).
Originally introduced to the public in 1993 with the theatrical release of
Jurassic Park, DTS Digital Surround has become one of the most widely
used digital playback systems in movie theaters. DTS Digital Surround
competes with alternative discrete digital formats such as Dolby Digital
(AC-3) and Sony Discrete Digital Surround (SDDS).
For the consumer, DTS Digital Surround software is currently available on
a limited number of laser discs and music discs. Playback of DTS Surround
media REQUIRES the use of a DTS Surround decoder. Playback without an
appropriate decoder may cause serious damage to your system.
Lexicon
The AC-3 and DTS versions of the DC-1 give you new surround effects, as
well as features and menu items not found in previous versions. The DC-1’s
open architecture makes system upgrades such as adding DTS capability,
simple modifications which can be performed by any Lexicon dealer —
allowing your DC-1 to deliver the full potential of music and movies for
years to come.
Using the
Documentation
Terms Used in This Manual
This manual describes both the AC-3 Version 2.00 and the DTS versions of
the DC-1. It is designed to be used in conjunction with the DC-1 Owner's
manual (Base, THX and Dolby Digital Version). Even if you are familiar
with setup and use of the DC-1, please take the time to read this manual to
fully understand the new features and changes.
Changes to the DC-1 menus are described in Chapter 1. To make this
information more convenient, we have reproduced the entire Imput Configuration section of the manual, and the section on Record/Zone 2 operation, including the new menu items available with the DTS version. Use this
version when configuring your system, rather than the version in the
Owner's Manual. A complete replacement of the DC-1 Owner's Manual
Effects Chapter is presented here as Chapter 2.
For those who are upgrading from a previous DC-1 version, we have made
special annotations for the controls which have been altered in this version.
Look for the following symbol in the margins:
New
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 recorded.
PCM FX The term PCM FX (Pulse Code Modulation FX) is used to describe
all of the effects which are compatible with two-channel input signals
(analog or digital). The list of PCM FX available in the AC-3 and DTS Digital
Surround versions of the DC-1 is located in the INPUT CONFIG menu.
DC-1 Digital Controller

Installation and
Calibration
For optimal performance when using analog inputs, the unit must be driven
to its full input level without overloading. Despite industry attempts at
standardization, different sources have a wide range of output levels. To
compensate for this, each of the eight DC-1 analog inputs can be assigned
a different input gain, assuring optimum performance regardless of the
source. For use with a calibration tone, the Dolby reference point is indicated by an enlarged tick mark on the on-screen level meters.
The DC-1 GAIN function can be set to AUTO to monitor the analog input
level and automatically optimizes the input gain. If the signal level is too
high, input gain is automatically decreased to a point which does not cause
an overload. When the signal level remains low (>12dB below clipping for
2.5 minutes), the input gain is incremented in 1dB steps to maximize
dynamic range.
When MANUAL is selected, the display shows the last auto level setting. (If
the auto level feature has not been used, the display shows the last manually
entered level.) The auto level setting indicates the optimum input level
value as determined by the unit. The MENU ▲ and ▼ buttons increase or
decrease the input gain in 1dB increments for the selected input over a range
of -18dB to +12 dB. The setting is displayed in dB along with horizontal
bargraph meters on the on-screen display to indicate incoming signal level.
Input Gain
(Analog Inputs Only)
The DC-1 has eight inputs, each of which can be associated with any of the
five video and four digital audio inputs. Selecting Input Configuration from
the Setup menu displays a sub-menu which lists these inputs and allows
you to select them individually for adjustment. Each input has an identical
parameter sub-menu. V-DISC is shown below as an example.
Installation and
Calibration
Input Configuration
The GAIN control is only available
for analog inputs. Whenever a digital input is selected under AUDIO
IN, this control is turned off.

Lexicon
Input Level Meters
The input level meters are displayed when
you select the GAIN parameter for an
active input which has been selected in
the Setup menu.
Input Name
When GAIN is selected, two on-screen horizontal bar meters display peak
incoming signal level. The highest peak level is shown in dB in a separate
text line, and as an arrow in the the meter display. White, yellow and red
sections of the bar meter show increasing levels. The white portion is shown
in 3dB increments, the yellow and red portions are shown in 1.5dB increments. An enlarged block at -21dB indicates the reference level used with a
Dolby calibration tone source.
The peak level display can be refreshed by pressing DONE to exit, then
pressing SELECT to return to the display.
Each input has an associated name which is displayed during normal
operation whenever the input is selected. The default names correspond to
the labels on the DC-1 remote control and the front and rear panels. These
names can be customized to more accurately reflect your system configuration.
To assign a new name (up to 8 characters) for an input, select NAME from
the Input Configuration menu, and EDIT INPUT NAME from the submenu. The display will show the current name with a cursor marking the
character position to be modified. Use the MENU ▲ and ▼ buttons to select
a new character for that position, and SELECT to move the cursor to another
position. Press DONE twice to return to the Input Configuration menu.
Restore Input Name
Input Effect
"FX" Assignment

This control allows you to restore the factory name for the currently selected
input. Pressing SELECT displays the message PRESS SELECT TO RESTORE INPUT NAME. Pressing SELECT again restores the name and exits
to the Input Configuration menu.
The DC-1 has the ability to automatically load an effect whenever an input
is chosen. For example, if you primarily listen to CD’s with the CONCERT
HALL effect, the DC-1 can be set to load this effect when the CD input is
chosen. (You can listen to any similar type of effect using the EFFECT button
on the front panel or the remote control.) If you select USE LAST, the
DC-1 will load the last effect used for the selected input. Any effect can be
assigned to any or all of the eight inputs.
Installation and
Calibration
DC-1 Digital Controller
The AC-3 and DTS versions of the DC-1 can be set up to automatically
switch to an appropriate effect whenever PCM, AC-3 or DTS encoded
material is detected at the input. This allows one input to be used for
different formats. For example, in the factory default state of the DTS
version, the V-DISC input will automatically load the appropriate version
of Logic 7 when an AC-3, DTS, or PCM signal is present. The default
selections for input effect assignment are shown below for both the AC-3

Automatic
NOTE: When AUTOMATIC is selected for an input, and DTS software is being used, there may be
a brief burst of noise before playback begins. This is inherent in
the current generation of DTS software and does not represent a
problem with your DC-1. To avoid
this, set up an input as DTS only,
and use it for playback of DTS
software.
The FX FORMAT parameter in the Input Configuration menu allows the
DC-1's format switching option to be individually adjusted for each input.
Many "multi-format" source components, such as laser disc players, are
capable of outputting different signals depending on the software being
used. The DC-1 automatically identifies the format of incoming audio
signals, and selects an appropriate effect. The four selections available for
FX FORMAT on each input are: AUTOMATIC, PCM ONLY, AC-3 ONLY
and DTS ONLY. Each of these selections is described below.
When AUTOMATIC is selected, the DC-1 automatically identifies the
format of the incoming signal and selects an appropriate effect. Effects can
be chosen for each individual input and for each format in the INPUT
CONFIG menu.
To illustrate how AUTOMATIC would operate with a laser disc player, note
the following example which assumes an "AC-3 ready" laser disc player
used in conjunction with the Lexicon LDD-1 AC-3/RF Demodulator. This
example assumes the V-DISC input has the factory preset configuration
shown below, and that the LDD-1 is connected to COAX 1 on the DC-1.

The DC-1 V-DISC input is selected. A movie encoded with a Dolby Surround soundtrack is put in the laser disc player and starts to play. The LDD1 recognizes that the movie is not AC-3 encoded, and automatically routes
the laser disc player's PCM (2-channel digital) signal to the DC-1. The
DC-1 identifies the signal as PCM and automatically loads the LOGIC 7
effect (as specified in the INPUT CONFIG menu).
Now, assume the movie is replaced with one that is encoded with a Dolby
Digital (AC-3) soundtrack. When it begins to play, the LDD-1 recognizes the
signal as being AC-3 encoded and demodulates it for the DC-1. The DC-1
automatically loads the 5.1 Logic 7 effect.
DC-1 Digital Controller
The EFFECT ▲ and ▼ buttons are used to audition the other available AC-
3 effects and DOLBY DIGITAL is selected. At some point during the movie,
the PAUSE button on the laser disc player is pressed. This causes the laser
disc player to temporarily replace the AC-3 output signal with a PCM
signal. This change is recognized by the DC-1, which automatically loads
the Logic 7 effect (because in this example, AUTOMATIC is selected as the
setting of FX FORMAT and LOGIC 7 is selected as the PCM FX in the INPUT
CONFIG menu). Because the laser disc is paused, there is no audio. When
PAUSE is released, playback is resumed and the DC-1 automatically
reselects the DOLBY DIGITAL effect because it was the last effect selected
before the audio was paused. To go back to the default effect, simply press
the input button.
Now, the movie is replaced with a 5" music disc that is DTS encoded. When
the disc begins to play, the LDD-1 recognizes that it is not AC-3 encoded, and
automatically routes the signal to the DC-1. The DC-1 recognizes the DTS
signal and automatically loads the DTS LOGIC 7 effect*. The EFFECT ▲ and
▼ buttons are used to audition the other available DTS effects and DTS
MUSIC is selected. At some point, the skip button on the laser disc player
is pressed several times to advance to a different track . This causes the laser
disc player to temporarily replace the DTS output signal with a PCM signal
while it searches for the selected track. This change is recognized by the DC1, which automatically loads the Logic 7 effect (because in this example,
AUTOMATIC is selected as the setting of FX FORMAT and Logic 7 is
selected as the PCM FX in the INPUT CONFIG menu). Because the disc
player is searching, there is no audio. When playback is resumed, the DC1 automatically reselects the DTS MUSIC effect. To go back to the effect
selected as a default, simply press the input button.

NOTE: When AUTOMATIC is selected for an input, and DTS software is being used, there may be
a brief burst of noise before playback begins. This is inherent in
the current generation of DTS software and does not represent a
problem with your DC-1. To avoid
this, set up an input as DTS only,
and use it for playback of DTS
software.
If PCM ONLY is selected as the FX FORMAT for a given input, only PCM
effects in the DC-1 can be used. When the DC-1 receives a signal which is not
PCM encoded, it will mute and display "NO PCM AUDIO."
In the previous example, if PCM ONLY had been selected, rather than
AUTOMATIC, the DC-1 would have muted and displayed "NO PCM
AUDIO" when the AC-3 movie and the DTS music disc were being played.
* As the DC-1 is in AUTOMATIC mode, there may be a brief burst of noise before normal
playback begins.
PCM Only
New
NOTE: PCM ONLY is automatically selected for an input whenever ANALOG is selected as
the AUDIO IN setting, as AC-3
and DTS effects are incompatible with analog inputs.
