  • Page 16: Wiring Considerations

    Installation DC-1 Version 3 Digital Controller Wiring Considerations There is debate over the audible effects of different types of interconnects. Audio/Video Cables Good engineering practices have minimized the effect that cables might have on the inputs and outputs of the DC-1 — but feel free to evaluate different interconnects in your system.
  • Page 17 Installation Lexicon Input sources should be connected directly to the DC-1 inputs. Since TAPE, TUNER and CD are audio only, the video output will default to the video signal from VCR1. This allows TV or other video source viewing while different audio is playing, but can be changed in the INPUT CONFIG menu.

    DC-1, an outboard demodulator is required to turn this RF signal back into a digital bitstream. By performing the necessary demodulation outside the DC-1, the potential for RF interference is eliminated. The Lexicon LDD-1 is an excellent example of one such device.

    System System Configuration Configuration DC-1 Version 3 Digital Controller Restore Factory Defaults Although the DC-1 memory is cleared before it leaves the factory, it is good practice to restore the factory defaults with the following procedure before system configuration. Turn the DC-1 OFF with the remote control. Turn the unit back ON and immediately press and hold the MUTE button on the remote.

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-1.
  • Page 26 System Configuration Lexicon The DC-1 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-1.

    System Configuration DC-1 Version 3 Digital Controller Record/Zone 2 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 an additional “zone” 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.

    System Configuration Lexicon The EXTERNAL NOISE TEST loads the Pro Logic, Dolby Digital or DTS Music effect and uses the signal from the currently selected input for calibration. Once a test source is selected, a sub-menu showing each output level is displayed.
  • Page 35 System Configuration DC-1 Version 3 Digital Controller Subwoofer Peak Limiter Dolby Digital (AC-3) and DTS encoded sources can produce low frequency peaks that are much louder than those in matrixed Dolby Surround decod- ing. These higher levels may be troublesome in the home listening environ- ment, 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.

    System Configuration Lexicon This menu allows you to set the level of attenuation used whenever the Mute Level DC-1 MUTE function is engaged. In the Output Levels menu, attenuation levels of -10dB, -20dB, -30dB, -40dB, and FULL are available. This control in the Output Levels menu allows you to select the volume at Power On Volume which the DC-1 will power on.
  • Page 37 System Configuration DC-1 Version 3 Digital Controller Once you have entered the distance to the nearest speaker, the DC-1 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.

  • Page 49 PCM Effects and Parameters DC-1 Version 3 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 low frequencies (LARGE).
  • Page 50 PCM Effects and Parameters Lexicon 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.
  • Page 51 PCM Effects and Parameters DC-1 Version 3 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.

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.
