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.

Eight stereo analog audio inputs are switched with corresponding video inputs and fed to the Monitor outputs. Inputs are nominally labeled as originating from an audio tape player, tuner, CD player, an unspecified auxiliary source, a TV tuner, a Laser or Video Disc player, a DVD player, and a VCR.

2 ZONE2 and RECORD

Each pair of stereo audio outputs supplies the same signal according to the Record/Zone 2 input selection. Zone 2 output levels can be controlled independently for use with amplifiers and speakers in another room. Record can be expanded to two outputs using standard Y-connectors. Both outputs are muted in Standby.

3 MAIN OUTPUTS

Three stereo amplifier outputs are provided for front, side and rear speakers. Single monaural outputs are provided for the center speaker and the subwoofer. The audio outputs are muted in Standby.

4 IR Input, PWR and PGM TRIGGERS

The IR input is an 1/8" mono phone jack connector for input of IR data from any industry-standard IR source. Data is retransmitted by an IR LED mounted near the front panel IR receiver.

Two trigger outputs are provided on 4-pin removable screw terminals, and a 5-pin DIN connector, as shown in the expanded illustration above. The PWR trigger is high when the DC-2 is on, low in standby or when the unit is off. The PGM trigger can be enabled (high) or disabled (low) for specific input selections in the Input Configuration menu. High is indicated by either +12VDC or +5VDC, selectable via an internal jumper. (Factory configuration is +12V.)

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

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.

Amplifiers and Speakers

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.

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.

For optimal performance when using analog inputs, the unit must be driven to its full input level without clipping. Despite industry attempts at standardization, different analog sources have a wide range of output levels. To compensate for this, each of the eight DC-2 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 Input Level meters.

The DC-2 GAIN function can be set to AUTOMATIC 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 clipping. When the signal level remains low (>12dB below clipping for 2.5 minutes), the input gain is increased in 1dB steps to maximize dynamic range.

The DC-2 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-2 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 FX button on the remote control.) If you select USE LAST, the DC-2 will load the last effect used for the selected input. Any effect can be assigned to any or all of the eight inputs.

DC-2 Digital Controller

The DC-2 can also 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, 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. More information is provided in the following FX Format section.

System

Configuration

The FX FORMAT parameter in the Input Configuration menu allows the DC-2'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-2 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-2 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 2 on the DC-2.

System Configuration

Lexicon

The DC-2 V-DISC input is selected. A movie encoded in Dolby Surround is put in the laser disc player and starts to play. The LDD-1 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-2. The DC-2 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 in Dolby Digital (AC-3). When it begins to play, the LDD-1 recognizes the signal as being AC-3 encoded and demodulates it for the DC-2. The DC-2 automatically loads the 5.1 Logic 7 effect.

The FX ▲ 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-2, 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-2 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 encoded in DTS. 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-2. The DC-2 recognizes the DTS signal and automatically loads the DTS LOGIC 7 effect*. The

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 DC-2, 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 DC-2 automatically reselects the DTS MUSIC effect. To go back to the effect selected as a default, simply press the input button.

* As the DC-2 is in AUTOMATIC mode, there may be a brief burst of noise before normal playback begins.

Configuration

If PCM ONLY is selected as the FX FORMAT for a given input, only PCM effects in the DC-2 can be used. When the DC-2 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-2 would have muted and displayed "NO PCM AUDIO" when the AC-3 movie and the DTS music disc were being played.

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-2 to mute and display "NO AC-3 AUDIO." The FX ▲ 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-2 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-2 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-2 to mute and display "NO DTS AUDIO." The FX ▲ and ▼ buttons

will select only DTS effects.

In our example, selecting DTS as the FX Format setting, would have caused the DC-2 to mute and display "NO DTS AUDIO" when the Dolby Surround and AC-3 movies were played. When the DTS music disc was advanced, the DC-2 would have muted briefly rather than automatically selecting the PCM effect Logic 7.

This option in the INPUT CONFIG menu determines which audio input connector on the DC-2 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 options availble for AUDIO IN are: ANALOG, COAX (1-5) and OPTICAL (1-3).

When ANALOG is selected for a given input, the DC-2 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 eight digital inputs is selected, the DC-2 will use it to derive the signal for the MAIN OUTPUTS. Note that all eight digital inputs can be used for various DC-2 inputs. This is particularly useful when using source components such as a laser disc or a DVD player to drive multiple DC-2 inputs.

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.

When using a PCM digital audio source sampled at 48kHz, the following effects will operate: PARTY, 2-CHANNEL, MUSIC SURROUND, MUSIC LOGIC, LOGIC 7, TV MATRIX, PRO LOGIC and THX CINEMA.

The inputs labeled VCR, DVD, 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 VCR video input. 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.

are separate outputs for easy integration of external recording devices as well as an additional “zone” in multi-room installations.

The Record and Zone 2 outputs on the DC-2 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 primary difference between the Record and Zone 2 outputs is that Zone 2 has its own volume control, while the Record output level is fixed.

Record/Zone 2The DC-2 is designed to be the control center of any system. As such, there

As protection against feedback, the TAPE and VCR 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 ▲ and ▼ to select REC/ZONE 2, then press SELECT. The ▲ and ▼

buttons will select ANALOG, DIGITAL, or BLOCKED as the state of the Zone 2 output.

ANALOG allows maximum flexibility from digital sources by utilizing both the digital and analog outputs of a digital source component (provided both are connected). The DC-2 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-2’s 24bit 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 24-bit D/A converters in the DC-2, sound quality can be dramatically improved when recording or listening in Zone 2. Note, however, that this setup automatically loads the appropriate 2-Channel effect 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-2 (Tape deck, VCR, etc.).

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

NOTE: Removing the block from any input which has both an input and output attached to the DC-2 may cause damaging feedback.

Note on External Noise

Calibration

Using a Sound Pressure Level Meter such as Radio Shack model 33-2050 or 33-2055, set the weighting to C and the response to Slow. Adjust all output levels to achieve 75dB at the listening position.

In the absence of an SPL meter, it is possible to set the output level by ear. Use the internal noise generator in the DC-2 to adjust all volumes to be the same as they cycle around the various speakers. Depending on timbre variations between your speakers, this may be difficult to judge — get as close as you can. The system should be reasonably well balanced, although not actually calibrated for precise playback and level matching. With the system volume at 0dB, the internal noise source should be at the same level at which film dialog sounds comfortable.

When using the external noise calibration, the DC-2 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-2 when external noise is engaged, the DC-2 will load the PRO LOGIC effect with the factory preset settings. If a Dolby Digital AC-3 signal is coming in, the DC-2 will load the DOLBY DIGITAL

effect with the factory preset settings. If a DTS signal is coming in, the DC-2 will load the DTS FILM effect with the factory preset settings.

Dolby Digital (AC-3) and DTS encoded sources can produce low frequency peaks that are much louder than those in matrixed Dolby Surround decoding. These higher levels may be troublesome in the home listening environment, either because they disturb non-listeners in nearby rooms, or because of the inability of the subwoofer and its associated amplifier to reproduce these levels without clipping.

Speaker Distance

The Speaker Distance control automatically sets the appropriate time delays for all of the loudspeakers in a system. Although this adjustment is not a substitute for proper speaker placement, it will help to ensure accurate signal arrival times from all channels at the listening position.

To set up Speaker Distance, you must physically measure the distance from the primary listening position to the front baffle of each individual speaker in your system. An easy and accurate way to accomplish this is to have a person sit in the primary listening position, holding the end of a measuring tape, while a second person extends the tape measure to the front baffle of each speaker in turn.

To enter these values, select SPEAKER DISTANCE in the Listener Position

menu and press SELECT. Use ▲ and ▼ to highlight feet or meters and press SELECT. Press SELECT again to highlight NEAREST SPKR. Use ▲ and ▼

to enter the actual distance, then press DONE.

Once you have entered the distance to the nearest speaker, the DC-2 will automatically calculate the maximum allowable distance. The display will show all of the speakers, each with a default distance setting equal to your

nearest speaker. Use SELECT and ▲ and ▼ to highlight and enter actual

distances for each speaker. The DC-2 rounds off distance settings into discrete steps – choose the closest step to the actual distance in these cases. If a speaker distance is further than the DC-2 can accommodate, set it to the maximum allowable distance. (This will vary, depending on your intial entry for NEAREST SPKR.)

System

Configuration

A/V Sync Delay compensates for the delay that occurs when a video processor, such as a scan converter, is used with the DC-2. Most of these processors alter the original audio/video timing relationship by adding delay to the video signal as it is processed. A/V Sync Delay applies a corresponding delay to the audio signal to restore the original audio/video timing relationship. It can also be used to compensate for poorly mastered source material.

If your video material appears to be out of sync, engage A/V Sync Delay in the LISTENER POSITION menu. With a video source running, adjust the

delay along its range with ▲ and ▼.

Note that it is best to use a non-film source when setting A/V Sync Delay, as film dialog added in post production may have poor timing relationships.

Panorama works by canceling the sound going from each speaker to the opposite ear. Its effectiveness is highly dependent on the geometry of your front loudspeakers, the room and your listening position. The correct timing of the canceling signal varies with the relative angle between your main speakers.

CAL NOISE is a special digitally generated signal to aid in calibrating the Speaker Angle and Listener Position parameters. Note that in all cases, sound will actually be produced by both front loudspeakers. The adjustments affect the perceived directionality of the sound.

The SPEAKER ANGLE, displayed in degrees, adjusts for wide or narrow speaker spacing (relative to the listening position). For the two canceling signals to arrive at both ears at the same time you must be centered precisely between the speakers. It will be easiest to calibrate this parameter if you start equidistant from the two front speakers, even if this is not your normal listening position. Once you have heard the effect and set the speaker angle, the Listener Position parameter will allow you to “move” the effect to your customary listening position.

To set the Speaker Angle, center yourself symmetrically between the two front speakers. Turn CAL NOISE on and select LEFT ONLY. The test signal should sound as though it is coming from off to your left side, well beyond the left speaker, with near-total silence in your right ear. Still facing forward, move your head from side to side until the effect is strongest. When you have found this sweet spot you will notice an almost physical sensation of silence in your right ear.

When calibrating right, if your left ear is in the silent band, the speaker angle is correct.

If the two silent bands are too close, lower the Speaker Angle; if they are too far apart, raise the Speaker Angle.

Now, select RIGHT ONLY. Again, shift your head from side to side to find the sweet spot, this time looking for the point where the sound is strongest in your right ear. Select LEFT AND RIGHT to determine if the sweet spots from the left and right tests coincide. If they do not coincide, return to the SPEAKER ANGLE display. If the first sweet spot is to the left of the second,

press ▲ ; if it is to the right, press ▼.

If your normal listening position is not centered between your two front speakers, once you have corrected the speaker angle setting, you can "move" the sweet spot to that position. To do this, select LISTENER POS and

use ▲ and ▼ to move the effect. As you adjust the position, the display will

indicate motion to the left of center (L001,L002,L003...L127), CENTER, or to the right of center (R001,R002,R003...R127). The numbers represent approximately 1/3", but are provided primarily as a general reference.

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 well 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-2 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 L/R main speakers 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 angle between the L/R main speakers.

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 vocal 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 matrix encoded films.

5 SPEAKER ENHANCE simulates 7 speaker playback through a 5 speaker system, providing a heightened sense of spaciousness and envelopment without extra speakers. This enhancement is most noticeable if the surround speakers are positionned directly to the side of the listening position, or if the listening position is located against the rear wall.

Note that, although this provides very convincing improvement to a 5 speaker system, it is not a substitute for a properly set up and calibrated 7 speaker system. The difference is most noticeable when the listener is seated to one side of the calibration position.

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.

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.

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.

BASS ENHANCE derives stereo bass to provide low frequencies that are noticeably less localizable and more spacious in the playback room.

DC-2 Digital Controller

Note that results will vary depending on room acoustics and the low frequency capacity of the surround speakers. As side and/or rear speakers are used for bass enhancement, the effectiveness is improved with speakers capable of reproducing reproducing low frequencies (LARGE). Using speakers that are not capable of producing low frequencies (<80Hz) may cause damage to them.

BASS RT (low frequency reverberation time) depends on MID RT and is expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for a more natural effect in smaller spaces.

CENTER LEVEL adjusts the output level from the center speaker.

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. In Panorama, this control changes the apparent width of the front soundstage. 0 = ordinary stereo, 62 provides the widest image.

PCM Effects and Parameters

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.

HALL SIZE allows you to select room sizes of lengths ranging from 4-38 meters, depending on the effect selected.

PCM Effects and Parameters

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

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.

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.

Lexicon

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.

MID RT (midrange reverberation time) is the time required for midrange sounds to decay 60dB in level.

PRE-DELAY increases the delay between the direct sound and the onset of reverberation. Because some pre-delay is inherent in the program material, a value of 0 is usually a good starting point. Increasing the pre-delay value will make the hall sound larger.

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.

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.

DC-2 Digital Controller

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.

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

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.

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

PCM Effects and Parameters

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

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

SOUNDSTAGE controls the level of the surround speakers relative to the front speakers in a dynamic way. The DC-2 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.

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

PCM Effects and Parameters

component of the input to the 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, Concert Hall, Church or Cathedral Effect with speech detect on.

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.

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.

Lexicon

SURROUND ROLLOFF allows the high frequencies of the surround 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.

SURROUNDS selects the type of surround decoding used by the DC-2. STEREO 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.

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

CENTER DLY SAMPLES adjusts the time offset of the center channel. The appropriate value is +0 unless you know that the center channel is not properly timed, as well as the amount by which it is off.

CENTER MIX adjusts the level of the center channel applied to the twochannel downmix. The appropriate value for film is 16. The appropriate value for music is 11.

COMPRESSION enhances the intelligibility of Dolby Digital material at low volume levels (-6dB or lower). When set to AUTO, this control automatically limits peak signals and boosts low level signals. The amount of compression increases proportionately as volume is decreased. This is quite useful when listening to Dolby Digital soundtracks at low output levels. When set to ON, full compression is applied, regardless of volume.

DC-2 Digital Controller

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.

MASTER LEVEL adjusts the output level of the two-channel downmix. This control should be set to +5dB unless the LFE is very heavy, inwhich case the level should be reduced.

AC-3 Effects and Parameters

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

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 EX (available as of software version 4) extracts and reproduces the additional rear channel mixed into SURROUND EX encoded soundtracks. This parameter is automatically set to ON when both SIDE and REAR speakers are selected in the SPEAKER CONFIGURATION menu, and will not operate unless SIDE and REAR speakers are selected. SURROUND EX decoding can be engaged during playback of non-SURROUND EX encoded 5.1 material, however, the information delivered to the rear channels may not be pleasing.

AC-3 Effects and Parameters

SURROUND MIX allows independent adjustment of the level of the surround channels. Many AC-3 encoded soundtracks sound better when down-mixed to two channels with the surround level increased by approximately 2-3dB.

VOCAL 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).

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.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.

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

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

Troubleshooting

If you encounter a problem, please review the items in the following checklist. Also be sure to thoroughly check all other connected components such as speakers, receiver/amplifier/preamp, VCR, TV, CD player, etc.

Troubleshooting

Problem Possible Cause and Solution

Power does not come on Check line cord to ensure good connection to the AC outlet and to the

receptacle on the DC-2 rear panel. Check to make sure that the DC-2 rear panel power switch is ON.

No audio Check the Status menu (under DISPLAY ADJUST: ON-SCREEN or

FRONT PANEL menu — or press and hold Record/Zone 2 on the remote and press OSD ON) to verify that audio is being received.

Remote control not working Check batteries to be certain that they are inserted correctly with proper

polarity. Make sure that the infrared sensor on the DC-2 front panel is not obstructed. See "If all else fails..." on the following page.

No output Make sure that signal is coming into the DC-2. (Check the Status menu

by pressing and holding Record/Zone 2 on the remote, then pressing OSD ON. This menu will display input level meters and sample rate, if applicable.) Increase VOLUME using the remote control and check Front/Back and Left/Right BALANCE.

Check the DC-2 MUTE controls to make sure they are not engaged. Check all other equipment settings and connections and verify that the

amplifiers being fed by the DC-2 are operational. Remember that the DC-2 mutes the output to any speakers which are

not configured in the Setup menu. If speakers are added to (or removed from) your system, the Speaker Configuration menu must be altered accordingly.

Center Channel only plays Check to see if your HiFi VCR has dropped out of tracking — readjust.

Your VCR Stereo/Mono/L-R switch may be in the wrong position — set it to Stereo.

Muffled sound in L&R channels When no center channel is used, CENTER must be configured for

NONE in the Setup Speaker Configuration menu.

Center channel sound muffled The center channel amp may be connected to the subwoofer jack on the

DC-2 rear panel. Reconnect to Center Output jack.

No Input Level Meters The meters will only appear when adjusting the Gain parameter of a

selected, active input, or when the Status menu is displayed.

No Video Make sure that video cables (particularly S-Video cables) are fully

inserted and that the appropriate connector is assigned to the VIDEO IN parameter in the Input Configuration menu.

Problem Possible Cause and Solution

Hum Finding and eliminating audio hum in a complex installation can be a

very frustrating task. Often, the easiest way to identify the culprit(s) is to systematically eliminate devices from the audio chain. If Cable TV is connected to any component in the system, start by unplugging the Cable completely, preferably right at the wall jack. If this eliminates, or greatly reduces the hum, it is worth a call to your Cable company. A

quick fix, assuming your cable is round 75Ω wire, is to attach a 75-300Ω transformer to the end, then attach a 300-75Ω transformer to that, so that the end is back to a round 75Ω wire. There are commercially

available antenna lead isolators which may provide additional insulation from electrical surges.

Interference with Radio or TV The DC-2 does generate minimal amounts of RF energy and is in

compliance with FCC rules and CE standards. If some interfering noise is noted, move AM loop and FM "T" type antennas away from the DC-2 and reorient them as necessary. Use shielded cable for FM and TV antenna feeds.

Erratic recall of modes Severe power surges or sags can confuse the DC-2 memory. To correct,

or if you simply want to start over, restore the factory defaults with the procedure described at the end of this section.

If all else fails… Turn off all amplifiers. Turn the master power switch on the DC-2 rear

panel OFF, wait 10 seconds, then turn it ON again. This causes the unit to run a diagnostic self-test routine which takes a couple of seconds. If the DC-2 LCD displays normally at the end of this test, no problems have been found with the DC-2 circuitry. If the internal tests fail, the LCD may display an error message, or no message at all. If this happens, contact your dealer or Lexicon Customer Service.

If you find that your custom settings are routinely being corrupted, the lithium battery in the DC-2 may need replacing. This part is not fieldreplaceable — contact your dealer or Lexicon Customer Service.

If the unit is still behaving erratically, perform the Restore Defaults procedure described on the following page.

Lexicon maintains a knowledge base on its website (www.lexicon.com) where you can find answers to frequently-asked questions and additional troubleshooting information.

DC-2 Digital Controller

Troubleshooting

Other than occasional replacement of the batteries in the remote control, the DC-2 requires minimal maintenance. Use a soft, lint-free cloth slightly dampened with warm water to clean the exterior surfaces of the unit.

Do not use alcohol, benzene or acetone-based cleaners

or any strong commercial cleaners.

Do not use abrasive materials such as steel wool or metal polish. If the unit is exposed to a dusty environment, a low-pressure blower may be used to remove dust from the DC-2 exterior.

or you simply want to start with a clean slate, you can restore all of the factory defults with the following procedure.

This will erase any programs you have stored,

as well as all setup and calibration values.

Note any settings you want to re-use before proceeding.

Turn the DC-2 OFF with the remote. Turn the unit back ON and immediately press and hold MUTE on the remote. (Make sure you do not block the infrared receiver on the DC-2 front panel.) The on-screen display will read:

RESTORE DEFAULTS

If you want to resume normal operation without restoring all defaults, this

is your last chance. Use MENU ▲ or ▼ to highlight EXIT, then press

SELECT.

Routine Maintenance

Restoring DefaultsIf severe power surges or sags cause problems with normal DC-2 operation,

To restore defaults, use MENU ▲ or ▼ to highlight RESTORE DEFAULTS,

then press SELECT. This will clear and reload all preset effects and all factory settings of Volume, Balance, Contrast, Configuration, etc.

When the message FACTORY DEFAULTS RESTORED is diplayed, press DONE to return to normal operation. All of the adjustable parameters in the DC-2 have now been reset to the values assigned when it cleared final Quality Control at the factory.

If you cannot solve functional problems through these procedures, consult your dealer or Lexicon Customer Service.
