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.

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

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 and DTS versions of the DC-1. More information is provided in the following FX Format section.

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.

Calibration

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.

AC-3 Only

New

NOTE: As AC-3 is a digital format, you must have a digital input selected for AUDIO IN in the INPUT CONFIG menu.

DTS Only

New

NOTE: As DTS is a digital format, you must have a digital input selected for AUDIO IN in the INPUT CONFIG menu.

When AC-3 ONLY is selected as the FX FORMAT, only AC-3 effects can be used on that input. Any other type of signal received on that input will cause the DC-1 to mute and display "NO AC-3 AUDIO." The EFFECT ▲ and ▼ buttons will select only AC-3 effects. This is recommended for any input which will be used only for AC-3 playback.

In our example, selecting AC-3 as the FX Format setting, would have caused the DC-1 to mute and display "NO AC-3 AUDIO" when the Dolby Surround movie and the DTS music disc were played. When the laser disc was paused, the DC-1 would have muted rather than automatically selecting the PCM effect Logic 7.

When DTS ONLY is selected as the FX FORMAT, only DTS effects can be used on that input. Any other type of signal received on that input will cause the DC-1 to mute and display "NO DTS AUDIO." The EFFECT ▲ and ▼ buttons will select only DTS effects.

In our example, selecting DTS as the FX Format setting, would have caused the DC-1 to mute and display "NO DTS AUDIO" when the Dolby Surround and AC-3 movies were played. When the laser disc was advanced to track 9, the DC-1 would have muted briefly rather than automatically selecting the PCM effect Logic 7.

Audio In

Earlier versions of the DC-1 had this menu item labeled DIGITAL. Selecting ANALOG in the current version is the equivalent of selecting NONE in previous versions.

Analog

COAX-1, 2 and

OPTICAL-1, 2

(Digital Audio Inputs)

This option in the INPUT CONFIG menu determines which audio input connector on the DC-1 rear panel will be used for the MAIN zone. Using the digital inputs will always yield better performance, and these should be used whenever a source component has a digital audio output. The five options availble for AUDIO IN are: ANALOG, COAX-1, COAX-2, OPTICAL-1 and OPTICAL-2.

When ANALOG is selected for a given input, the DC-1 will use the corresponding analog stereo audio input to generate the MAIN OUTPUTS. Note that selecting ANALOG will automatically select PCM ONLY as the FX FORMAT as the AC-3 and DTS effects are only compatible with digital inputs.

When one of these four digital inputs is selected, the DC-1 will use it to derive the signal for the MAIN OUTPUTS. Note that all four of the digital inputs can be used for multiple DC-1 inputs. This is particularly useful when using source components that support multiple formats, such as a laser disc, compact disc or DVD player.

Installation and

Calibration

The inputs labeled VCR-1, VCR-2, V-DISC, TV and AUX normally have corresponding video inputs. The inputs labeled CD, TUNER, and TAPE do not have associated video inputs, and default to the video input VCR1. For maximum configuration flexibility, each of the five video inputs can be assigned to a different input, or to multiple inputs. If the assigned video input has both S-Video and composite jacks, the S-video signal takes priority whenever a cable is plugged into the appropriate S-video connector. (In previous versions of the DC-1, this control was labeled "Video".)

The DC-1 is designed to be the control center of any system. As such, there are separate outputs for easy integration of external recording devices as well as additional “zones” in multi-room installations.

The Record and Zone 2 outputs on the DC-1 are wired in parallel so that the input selection will always be the same for both. For example, if the CD input is selected for Record, the CD input is also output to Zone 2. The only difference between the Record and Zone 2 outputs is that Zone 2 has its own volume control, while the Record output level is fixed. When the DC-1 is powered up, the Zone 2 output is muted.

The DC-1 does not normally assign any input selected for the Main zone (indicated by a lit green LED at the front panel input button), to the Record and Zone 2 outputs. Audio is only present at the Zone 2 outputs when an input is selected for Record/Zone 2. The procedure for assigning these outputs is described below.

Video In

NOTE: S-Video input signals will be output on both the composite and S-Video jacks. However, if you are only connecting to the monitor via the S-Video output, composite video input sources will not be displayed.

RECORD/ZONE 2 Operation

To assign the current input to the Record/Zone 2 outputs, press and hold REC/ZONE 2 until the red LEDs at the appropriate front panel input button and at the front panel REC/ZONE 2 button light.

To clear the assignment, press and hold REC/ZONE 2 until the LEDs turn off.

For Example: CD is selected for the Main output (and its front panel green LED is lit). Pressing and holding down the remote control or front panel REC/ZONE 2 button will light the red LED above the front panel REC/ZONE 2 button as well as the red LED above the currently selected input (CD).

You have now assigned CD to the Record/Zone 2 outputs. In this state, new input selections will not affect the Record/Zone 2 outputs.

Now, suppose you want to change the Record/Zone 2 assignment to the TUNER input. To do this, press CD and press and hold REC/ZONE 2 until the red front panel LEDs turn off.

Lexicon

You have now cleared the previous Record/Zone 2 assignment. To assign TUNER to the Record/Zone 2 outputs, press and hold REC/ZONE 2 again. The red LED above the front panel REC/ZONE 2 button as well as the red LED above the TUNER input will light.

NOTE: When using DTS material from a source component, the raw DTS digital data is also sent out of the analog outputs. Raw DTS data, which sounds like loud white or pink noise, may cause damage to a system.

NOTE: Removing the block from any input which has both an input and output attached may cause damaging feedback.

As protection against feedback, the TAPE and VCR1 inputs are normally blocked from being used as sources for the Record and Zone 2 outputs. This default condition can be changed in the Input Configuration menu as follows.

Use MENU ▲ and ▼ to select REC/ZONE 2, then press SELECT. The MENU ▲ and ▼ buttons will select ANALOG, DIGITAL, or BLOCKED

as the state of the input.

ANALOG allows maximum flexibility when utilizing both the digital and analog connections of a digital source component (provided both are connected). The DC-1 processes the digital input signal for the main zone, and simultaneously routes the analog input signal to the Record and Zone 2 outputs. Since no D/A converters are necessary for the analog input signal, the functionality in the Main zone is not compromised.

DIGITAL routes the digital signal, assigned to the input, to the DC-1’s 20bit Digital to Analog (D/A) converters. After conversion, the signal is sent to the Record and Zone 2 outputs. As this setup bypasses the D/A converters in the source component, and utilizes the 20-bit D/A converters in the DC-1, sound quality can be dramatically improved when recording or listening in Zone 2. This setup automatically engages Effect Bypass in the main zone.

BLOCKED simply blocks the input from being sent to the Record and Zone 2 outputs. This prevents feedback from occurring with devices that have both an input and output attached to the DC-1 (Tape deck, VCR, etc.).

Zone 2 Remote Control

The remote control can be placed into an exclusive Record/Zone 2 control mode during normal operation by holding down ACCY and pressing RECORD/ZONE 2. This will display the message:

ZONE 2 IR REMOTE

Installation and

Calibration

The DC-1 can also be used as an exclusive Zone 2 controller, allowing remote use of the system while the local room(the room in which the DC-1 is located) remains muted. To use the DC-1 in this manner, turn on the DC-1 by pressing the RECORD/ZONE 2 key on the remote. The unit will power up with the System Mute and Effect Bypass activated. The remote will default to Zone 2 IR Remote mode as described above, with Volume, Mute, Input Selection and L/R Balance controlling only the Record and Zone 2 outputs. To return to normal operation, simply press OFF, then ON.

Digital audio inputs can be selected for the Record/Zone 2 outputs under the following conditions:

• The digital input must be assigned to an input via the Setup: Input Configuration menu.

• The input must have REC/ZONE 2 set to DIGITAL. (TAPE and VCR1 are normally "BLOCKED", but can be changed in the Input Configuration menu.)

• The input must be selected for Main outputs.

Exclusive Zone 2 Control

This menu item assigns the status for the remote trigger that appears on pin 5 of the Power Control DIN jack on the DC-1 rear panel. +12VDC is provided for controlling ancillary equipment or functions. This signal can be ENABLED or DISABLED for the selected input. The factory default is ENABLED (high) for A/V inputs and DISABLED (low) for audio only inputs. (+5VDC is available via internal jumper.

Note on External Noise

Calibration

When using the external noise calibration, the DC-1 will load the factory default effect for the format of the incoming signal. In other words, if a PCM signal is coming into the DC-1 when external noise is engaged, the DC-1 will load the PRO LOGIC effect with the factory preset settings. If a Dolby Digital AC-3 signal is coming in, the DC-1 will load the DOLBY DIGITAL effect with the factory preset settings. If a DTS signal is coming in (and the DC-1 is the DTS Version), the DC-1 will load the DTS MUSIC effect with the factory preset settings.

DC-1 Effects

When EFFECT ADJUST is selected from the Main menu, the on-screen display shows a list of parameters specific to the current effect, as well as the current value of each parameter. (The front panel display shows one parameter at a time). Press the MENU ▲ and ▼ buttons to move through the displayed list. Press SELECT to activate a two-line display which allows you to use the ▲ and ▼ buttons to alter the selected parameter’s value. Press DONE to confirm the change and move on to the next menu item. Each DC-1 Effect and its parameter menu is described in the following section.

Although the list of available parameters will vary with different effects, the last item in each menu is always CUSTOM. Selecting CUSTOM calls up a sub-menu which allows you to name your custom effects, to compare your version with the original preset, or to restore the preset versions of the Effect name and parameter values.

When first shipped, the DC-1 has a set of default values assigned to each Effect. These values have been determined to be generally suitable for initial listening. As every installation has its own unique characteristics, and listeners have distinctly different preferences, you will want to tailor the Effects to suit your own requirements. To allow easy cutomization, any parameter changes you make take effect instantly, and automatically become a part of the Effect. You can even change the name that appears onscreen. Once you have made the changes you want, the Effect will remain as you have set it unless you alter it again, or deliberately restore the factory preset parameter values.

Selecting CUSTOM from any Effect Adjust menu will give you access to the controls listed to the side and described below. Use MENU ▲ and ▼ to highlight any menu item, then press SELECT to open the submenu.

LISTEN CUSTOM/PRESET lets you compare your edited version of an Effect with the original version as set at the factory. When this control is selected, MENU ▲ and ▼ allow you to alternate between the "preset" and your modified version ("custom"). The display will confirm whether you are LISTENING TO CUSTOM or PRESET.

Note that this function is available, even if you have not made any changes to an Effect. Until you make parameter changes to create a custom version of a preset, the LISTEN TO CUSTOM option will contain an exact duplicate of the preset Effect.

Exiting this menu restores the CUSTOM version.

Music Surround, available in the THX, Dolby Digital and DTS versions of the DC-1, is a surround effect developed specifically for classical music listening. It makes full use of additional loudspeakers placed at the center, sides and rear of the room. This effect passes unprocessed left and right information directly to the front left and right speakers.

CENTER LEVEL attenuates the level of the center channel and can turn it off completely.

SOUNDSTAGE controls the level of the surround speakers relative to the front speakers in a dynamic way. The DC-1 attempts to detect whether or not the sound source was originally encoded from a surround source by looking for occasional bursts of rear-steered material, and by identifying the directional orientation of the background sound between strong sounds. Whenever there is an indication that the source was originally surround encoded, the Soundstage control automattically reverts to the REAR setting — which gives the rear speakers full level. The NEUTRAL position attenuates the rear speakers 3dB. The FRONT position attenuates the rear speakers 6dB. The effect is to move the listening position forward in the listening space.

Music Surround Parameters

SIDE ROLLOFF provides a high frequency cutoff for the side speakers. The optimal setting for this control will vary widely with the source material.

REAR ROLLOFF sets the cutoff frequency of a low pass filter in the rearchannel. Frequencies above this setting are attenuated. This control should be set high enough to give presence and airiness to the rear sound without placing distracting instrumental overtones or other sounds behind you. In systems configured without rear speakers, the settings affect the side out- puts.

REAR DELAY OFFSET is an additional delay added to the rear channels. This delay increases the apparent size of the listening space by increasing the rear delay time. Feel free to experiment to find the setting that works best.

SURROUND LEVEL controls the volume level of the side and rear speakers. Although we have selected a default value, the correct setting will vary with each recording, the room, and your personal taste.

SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.

EFFECT LEVEL adjusts the loudness of the center, side and rear speakers. When there are no side or rear speakers, it adjusts the amount of ambient signal mixed into the main loudspeakers.

This Effect provides Dolby Pro Logic Surround decoding designed for any Dolby Surround encoded movies, music, or television programs. The Pro Logic effect is an industry standard. Lexicon's proprietary auto azimuth correction makes it an improvement over other versions. (Even more dramatic improvement has been implemented in more recent effects, such as Logic 7 or TV Matrix.)

AUTO AZIMUTH is short for auto azimuth error correction/automatic input balance. Auto Azimuth should be set to ON for films, and OFF for music. When ON, special patented algorithms continually monitor the input signal and adjust both the relative level and time offset of the two channels to keep the dialog properly centered and special effects properly localized. This automatic feature is the reason the unit does not need an input balance control for Dolby Surround decoding.

DIALOG ENHANCE boosts dialog in the center channel. By targeting specific frequencies, it boosts dialog without raising the entire center channel level (which would alter the output balance achieved during calibration).

SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.

EFFECT LEVEL adjusts the loudness of all speakers except the center and subwoofer channels. This can be extremely useful in compensating for soundtracks in which the dialog level is too low (decrease EFFECT LEVEL) or when you want to make the surround presentation more spectacular (increase EFFECT LEVEL).

RE-EQUALIZER equalizes the left, center, and right channel outputs to match the overall frequency balance of the original recording. Without this re-equalization, many films and some television programs will sound too bright.

SURROUND MODE selects the type of surround decoding used by the DC-1. STEREOPHONIC provides extraction of five channels of surround information from a standard 4-2-4 matrix-encoded soundtrack (Dolby Surround, Ultra*Stereo, etc.) The drama of this effect is dependent on the source material and is most noticeable with strong stereo music soundtracks. The DECORRELATED setting electronically scrambles the monaural surround channel to provide added spaciousness and envelopment.

This film sound mode reproduces musical material with maximum separation at all times, whether or not directional material is being steered. In addition, Logic 7 uses intelligent steering to extract wide bandwidth stereo surround channels. If both side and rear speaker pairs are available, signals may be steered between the left side and left rear, or between the right side and right rear. It is also possible for a signal to be steered fully to the rear speakers, with the side surround speakers 6dB lower than the rears to provide subjective rear imaging.

Logic 7 contains the re-equalizer feature of the THX Cinema effect, as well as Lexicon's proprietary dialog enhancement feature. The combination of stereo surround information during music and decorrelated effects, with discrete steering to the sides and rears, gives Logic 7 unrivaled performance on surround encoded films.

FRONT STEERING provides four basic settings which have been developed specifically to optimize center channel signal strength for film and music. The MUSIC setting is designed for classical and popular music. It preserves nearly the full width of the front image, even in complex material with a high vocal level. At the same time, it reproduces film with plausible separation between the center speaker and the front speakers during dialog.

The FILM setting has excellent frontal image stability through the whole room during dialog and vocals, while preserving the full width of the front image in the spaces between dialog, and for music without vocals. The front image during vocals is noticeably narrower than with the MUSIC setting, but highly satisfactory nonetheless.

1/2 is similar to the MUSIC setting under most conditions, but will reproduce sound in all three front speakers when a strongly centered, or mono signal is present. This is an excellent choice for heavily centered pop music such as metal and sounds more natural for broadcast material with a single announcer. OFF sets the center channel level to 4.5dB less than the front left and right speakers, and then leaves the level unchanged as the steering varies. This setting is equivalent to conventional stereo with a slight center fill.

Mono Logic takes a monaural soundtrack and sends music and sound effects to the sides and rear through a room simulator mode while keeping the dialog in the center.

Parameter Initial Value Range

MAIN LEVEL controls the level of the mono signal that is reproduced by the main speakers. When a center speaker is part of the configuration many films may sound better when this control is set between 6-12. This spreads the film sound out around the screen and can be more pleasant than restricting the dialog and much of the other film sound to the center speaker.

ACADEMY FILTER is provided to recreate the proper tonal balance of older monaural films that were recorded with much narrower and duller frequency response than current films.

ROLLOFF regulates the treble cut in the side and rear channels. The optimal setting for this parameter will vary widely with the age, quality, and condition of the source material.

SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.

EFFECT LEVEL adjusts the loudness of the side and rear speakers. When there are no side speakers, it adjusts the amount of ambient signal mixed into the main loudspeakers.

Panorama extracts the natural ambience from recorded music and moves it outward from the speakers, producing greater width and depth of image and a feeling of enhanced spaciousness. This mode adds no additional sound but expands the existing stereo image. Panorama also works with Dolby Stereo movies, bringing the surround track outward into the room.

The location of the front speakers and the listening position are crucial to Panorama’s effectiveness and for best results your system and the DC-1 together should be set up and calibrated according to the procedure in Chapter 2. The strength of the Panorama effect drops off as you move away from the prime listening position, especially to the sides. Video systems with the main loudspeakers spaced closely on either side of a TV screen will produce a usable effect over a somewhat wider area than set-ups with a large included angle between the speakers.

INPUT BALANCE allows you to compensate for the occasional source with audible channel imbalance. When selected, screen graphics indicate the relative left/right position.

CENTER LEVEL adjusts the output level from the center speaker.

REAR ROLLOFF sets the frequency above which the rear-channel sound is attenuated. The appropriate setting will vary with the program material. It should be set high enough to give presence and airiness to the rear sound without placing distracting instrumental overtones or other sounds behind you. The settings also affect the side outputs.

REAR DELAY adjusts the amount of time between the appearance of a signal in the front channels and its emergence from the rear. Generally, the correct delay is about 16 milliseconds, but the setting depends on speaker set-up and source material. In general, the delay should be low enough so that the rear sound does not become identifiable as a distinct source. The settings also affect the side outputs.

SURROUND LEVEL adjusts the loudness of the signals sent to the rear channels. This control should be set so that the rear is audible without calling attention to itself. Numerical values and screen graphics are displayed during adjustment. The settings also affect the level of the side outputs.

BASS CONTENT allows you to modify the bass content for Mono, Stereo or Binaural recordings. The BINAURAL setting turns the rear level parameter off and activates special low-frequency compensation. This feature is offered specifically for true binaural recordings made with a dummy head.

LOW FREQ WIDTH allows you to apply low-frequency spatial correction to the signal. Positive values of LOW FREQ Width indicate that the difference signal (L-R) has additional energy below 500Hz, while the sum (L+R) has correspondingly less. Negative settings of LOW FREQ WIDTH can compensate for recordings with too much of this property. This control can add needed spaciousness and warmth to classical recordings made with coincident or near-coincident microphones.

SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the normal subwoofer level is set during the calibration procedure, with some recordings it may be desirable to increase or decrease this deep bass level.

SPEECH DETECT activates a circuit that distinguishes monaural speech from other inputs. Essentially, this control turns down the effect to make speech clearer. Whenever stereo signals are present, the right and left input channels are used independently as inputs to the ambience synthesis. If there is a strong monaural speaking voice present at the same time, this component of the input to the Nighclub effect is reduced while the stereo component is increased.

If the input signal is pure monaural speech the reverb is almost entirely attenuated. SPEECH DETECT is a real benefit to some popular music (where spoken voice, such as rap, occurs along with the music), stereo television and early stereo movies. Any stereo material which was not carefully mixed for Surround is a good candidate for playing through the Nightclub Effect with speech detect on.

HALL SIZE allows you to select room sizes of lengths ranging from 4-17 meters.

LIVENESS adjusts the amount of recirculation within the effect. Higher values mimic more reflective surfaces in the simulated space and increase the amount of time it takes the sound to decay. At very high values, the decay is audibly less smooth than in the Church and Cathedral Effects, which are more effective at simulating very live spaces.

ROLLOFF mimics the absorption of the air in the hall and, typically, should begin with a low frequency to simulate large spaces.

Music Logic is a surround effect developed specifically for music listening. It makes full use of additional loudspeakers placed at the center, sides and rear of the room and provides a slight degree of steering for the front channels.

FRONT STEERING provides four basic settings which have been developed specifically to optimize center channel signal strength for film and music. The MUSIC setting is designed for classical and popular music. It preserves nearly the full width of the front image, even in complex material with a high vocal level. At the same time, it reproduces film with plausible separation between the center speaker and the front speakers during dialog.

The FILM setting has excellent frontal image stability through the whole room during dialog and vocals, while preserving the full width of the front image in the spaces between dialog, and for music without vocals. The front image during vocals is noticeably narrower than with the MUSIC setting, but highly satisfactory nonetheless.

1/2 is similar to the MUSIC setting under most conditions, but will reproduce sound in all three front speakers when a strongly centered, or mono signal is present. This is an excellent choice for heavily centered pop music such as metal and sounds more natural for broadcast material with a single announcer. OFF sets the center channel level to 4.5dB less than the front left and right speakers, and then leaves the level unchanged as the steering varies. This setting is equivalent to conventional stereo with a slight center fill.

SOUNDSTAGE controls the level of the surround speakers relative to the front speakers in a dynamic way. The DC-1 attempts to detect whether or not the sound source was originally encoded from a surround source by looking for occasional bursts of rear-steered material, and by identifying the directional orientation of the background sound between strong sounds. Whenever there is an indication that the source was originally surround encoded, the Soundstage control automattically reverts to the REAR setting — which gives the rear speakers full level. The NEUTRAL position attenuates the rear speakers 3dB. The FRONT position attenuates the rear speakers 6dB. The effect is to move the listening position forward in the listening space.

REAR DELAY OFFSET is an additional delay added to the rear channels when listening to LOGIC 7 and MUSIC SURROUND. This delay increases the apparent size of the listening space by increasing the rear delay time. Feel free to experiment to find the setting that works best.

SURROUND ROLLOFF allows the high frequencies of the rear channels to be attenuated with the same detection circuitry as that described for the Soundstage control. The attenuation is quite attractive on many music and broadcast sources which were not mixed for surround. When a surround source is detected, these filters are removed, so the rear speakers can reproduce surround events with full bandwidth. This control should be set high enough to give presence and airiness to the rear sound without placing distracting instrumental overtones or other sounds behind you. The settings also affect the side outputs.

The Dolby Digital version of the DC-1 provides an AC-3 Status Display in the parameter menu. This display contains the following information.

MATRIX ENCODED: YES indicates a Dolby Digital input is matrix encoded; No indicates it is not.

DOWNMIX: YES indicates material is being downmixed for speaker configuration. NO indicates no downmixing is taking place, except in the 5.1 Two-Channel Effect, which is designed to create a two-channel version of

5.1 channel material.

DATA RATE: 32-640kb, depending on the data rate of the incoming signal.

SAMPLE RATE: 44.1kHz or 48kHz depending on the incoming signal.

PGM CONTENT: shows you the actual spatial characteristics of the incoming soundtrack. The information appears as F/S.LFE where F=the number of front channels and S=the number of surround channels. LFE=.1 if the LFE channel is on.

For example, a given source may display 3/2.1, indicating that the source was recorded with 3 front channels, 2 surround channels, and the LFE channel. When the designation .1 indicates that the LFE channel is on, as in our example, a level meter at the bottom of the display will show LFE channel activity. (Note, that there are instances where the LFE channel is on, but no activity shows in the meter display. This is normal and should not cause concern.)

REF OFFSET indicates the Dialog Normalization value that is present in AC-3 bitstreams. In AC-3, dialog is reproduced at -31dBFS (31dB below full scale). If the program material was mixed so that dialog is at -31dBFS, then REF OFFSET=0dB. If the dialog was mixed at a "hotter" level, for example,

-21dBFS, then REF OFFSET = -10dB and the DC-1 would adjust the levels down 10dB to bring dialog back to -31dB.

DIALOG ENHANCE boosts dialog in the center channel. By targeting specific frequencies, it can boost only dialog, without raising the entire center channel level (which would alter the output balance achieved during calibration).

RE-EQUALIZER equalizes the left, center, and right channel outputs to match the overall frequency balance of the original recording. Without this re-equalization, many films and some television programs will sound too bright.

SIDE LEVEL controls the output level of the side speakers. Use this control in conjunction with SURROUND LEVEL to achieve the optimum balance between the side and rear speakers.

SURROUND LEVEL controls the volume level of the side and rear speakers. Although we have selected a default value, the correct setting will vary with each recording, the room, and your personal taste.

DTS Film Parameters

LFE MIX LEVEL allows separate level attenuation of the LFE channel, which is ultimately mixed to the subwoofer output. As the bass from as many as five other channels is added to the LFE, it can significantly raise subwoofer output levels — and create the risk of damage to a system. Careful adjustment of this parameter will allow you to achieve proper tonal balance and reduce the risk of damage.

DTS Logic 7 Parameters

DTS Logic 7 combines all the features of DTS Digital with enhancements by Lexicon and LucasFilm. This effect uses Logic 7 matrix technology to enhance the steering between the side speakers and the rear speakers, so sounds intended to come from behind the listener actually do come from behind. This effect also includes the adaptive decorrelation and re-equalizaer features of DTS THX.

DTS Logic 7 provides the ultimate in film reproduction. It brings out all the increased excitement and spaciousness a 7 channel speaker system can produce.

This Effect provides THX 5.1 Cinema enhancements for film soundtracks recorded in the DTS format. This processing compensates for the acoustical differences between large mixing theaters and the typically smaller home environment. In this effect the side and rear speakers are driven in parallel when you designate side speakers as STANDARD (LARGE or SMALL) in the Speaker Configuration menu. When DIPOLE is selected, the rear outputs will mute.

This Effect mixes DTS Digital 5.1 information for two-channel playback. These soundtracks can be recorded onto two-channel formats, or played back through left and right front speakers. The mix is designed to play back with full surround when decoded through Logic 7. In mixing a film with very heavy use of the Low Frequency Effects Channel, it may be desirable to lower LFE MIX LEVEL.
