[. . . ] Owner's Manual DC-2 Digital Controller Important Safety Instructions Save these instructions for later use. Refer to the manufacturer's operating instructions for power requirements. Be advised that different operating voltages may require the use of a different line cord and/or attachment plug. Do not install the unit in an unventilated rack, or directly above heat producing equipment such as power amplifiers. [. . . ] 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. 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 FX v and w 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 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). 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. 18 DC-2 Digital Controller System Configuration PCM Only 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. 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 v and w 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. AC-3 Only NOTE: As AC-3 is a digital format, you must have a digital input selected for AUDIO IN in the INPUT CONFIG menu. 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 v and w 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. DTS Only NOTE: As DTS is a digital format, you must have a digital input selected for AUDIO IN in the INPUT CONFIG menu. 19 System Configuration Audio In Lexicon 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). Analog 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. COAX 1-5 and OPTICAL 1-3 (Digital Audio 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. [. . . ] 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. To correct, or if you simply want to start over, restore the factory defaults with the procedure described at the end of this section. Turn the master power switch on the DC-2 rear panel OFF, wait 10 seconds, then turn it ON again. [. . . ]
