  • Page 9 Introduction Thank you for your purchase of this upgrade for your DC-1. This Owner's Manual Addendum is designed to provide supplementary information for systems with Dolby Digital® AC-3 Version 2.00 or DTS® software installed. About Dolby Digital AC-3 Encoding Because multichannel recordings are made up of so much information, new ways of storing and transmitting data have been created.
  • Page 10 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.

  • Page 12: Input Configuration

    Installation and Installation and Calibration Calibration DC-1 Digital Controller Input Configuration 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.

  • Page 13: Input Level Meters

    Installation and Calibration Lexicon Input Level Meters 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.

  • Page 14: Input Effect "Fx" Assignment

    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.

  • Page 15: Fx Format

    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.
  • Page 16 Installation and Calibration DC-1 Digital Controller The EFFECT 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.

  • Page 17: Audio In

    Installation and Calibration Lexicon AC-3 Only 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 buttons will select only AC-3 effects.

  • Page 18: Video In

    Installation and Calibration DC-1 Digital Controller The inputs labeled VCR-1, VCR-2, V-DISC, TV and AUX normally have Video In 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 NOTE: S-Video input signals will be assigned to a different input, or to multiple inputs.
  • Page 19 Installation and Calibration 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.

    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. Contact your dealer or Lexicon Customer Service to perform this change.)

  • Page 21: Note On External Noise Calibration

    Installation and Calibration Lexicon Note on External Noise 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 Calibration 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.

  • Page 24: Music Surround

    DC-1Effects DC-1 Digital Controller Music Surround 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.

  • Page 25: Pro Logic

    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.)

  • Page 26: Thx Cinema

    DC-1Effects DC-1 Digital Controller THX Cinema This Effect, available only in DC-1s equipped with THX, Dolby Digital or DTS processing, provides Home THX Cinema surround decoding for any Dolby surround encoded movies, music or television programs. The effect is similar to Pro Logic, but includes the features of re-equalization, timbre matching and decorrelation.

  • Page 27: Logic 7

    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.
  • Page 28 DC-1Effects DC-1 Digital Controller 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 attenu- ates the rear speakers 3dB. The FRONT position attenuates the rear speakers 6dB.

  • Page 30 DC-1Effects DC-1 Digital Controller 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. SOUNDSTAGE controls the level of the surround speakers relative to the front speakers in a dynamic way.

  • Page 32: Panorama

    DC-1Effects DC-1 Digital Controller Panorama 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.
  • Page 33 DC-1 Effects Lexicon 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 dis- played during adjustment. The settings also affect the level of the side outputs.

  • Page 35: Concert Hall

    DC-1 Effects Lexicon Concert Hall The Concert Hall Effect generates the appropriate early reflections for stereo simulation of many different halls, and sends the reflections to all channels in addition to the direct signal in the main speaker. This Effect is not appropriate for highly percussive music.

  • Page 36: Church

    DC-1Effects DC-1 Digital Controller Church The Church Effect uses a reverberation algorithm, which differs from ambience in that it does not simulate the reflections of specific halls, but emphasizes rich, smooth reverberant decay in small and medium spaces. It works well for simulating a space with a long reverberation time relative to its size, such as a reverberant chamber, or a church.

  • Page 37: Cathedral

    DC-1 Effects Lexicon ROLLOFF mimics the absorption of the air in the hall and, typically, should begin with a low frequency when simulating larger spaces. 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.

  • Page 38: Music Logic

    DC-1Effects DC-1 Digital Controller HALL SIZE allows you to select hall sizes of lengths ranging from 20-38 meters (in increments of 2 meters). 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.
  • Page 39 DC-1 Effects Lexicon FRONT STEERING provides four basic settings which have been devel- oped 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.

    DC-1Effects DC-1 Digital Controller 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.

  • Page 41: Ac-3 Status Display

    DC-1 Effects Lexicon AC-3 Status Display 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 en- coded; No indicates it is not.
  • Page 42 DC-1Effects DC-1 Digital Controller AC-3 STATUS displays the current status of incoming AC-3 data. The displayed items are not user adjustable. COMPRESSION enhances the intelligibility of Dolby Digital material at low volume levels (-6dB or lower). When set to AUTO, this control auto- matically limits peak signals and boosts low level signals.

  • Page 43: Dolby Digital

    In this effect, any rear speakers present are connected in parallel with the side speakers. This is the basic Dolby AC-3 effect. It does not include the enhancements by Lexicon or LucasFilm which are available with other AC- 3 effects in the DC-1.
