Always use with the correct line voltage. Refer to the manufacturer's operating instructions for power requirements. [. . . ] 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 MC-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 disc player is searching, there is no audio. When playback is resumed, the MC-1 automatically reselects the DTS MUSIC effect. * To go back to the effect selected as a default, simply press the input button. * As the MC-1 is in AUTOMATIC mode, there may be a brief burst of noise before normal playback begins. 18 MC-1 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 MC-1 can be used. When the MC-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 MC-1 would have muted and displayed "NO PCM AUDIO" when the AC-3 movie and the DTS music disc were being played. 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 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 MC-1 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 MC-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 MC-1 would have muted rather than automatically selecting the PCM effect Logic 7. DTS Only 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 MC-1 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 MC-1 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 MC-1 would have muted briefly rather than automatically selecting the PCM effect Logic 7. There would not have been any brief bursts of noise before playback began. 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 MC-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 options available for AUDIO IN are: ANALOG, COAX (1-5) and OPTICAL (1-3). Analog When ANALOG is selected for a given input, the MC-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. COAX 1-5 and OPTICAL 1-3 (Digital Audio Inputs) When one of these eight digital inputs is selected, the MC-1 will use it to derive the signal for the MAIN OUTPUTS. Note that all eight digital inputs can be used for various MC-1 inputs. This is particularly useful when using a source component such as a VCR, laser disc or DVD player to drive multiple MC-1 inputs. 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. NOTE: The Expansion Port input cannot be assigned as the default for any input. Video In NOTE: S-Video input signals will be output on both the composite and SVideo jacks. [. . . ] If the MC-1 LCD displays normally at the end of this test, no problems have been found with the MC-1 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 MC-1 may need replacing. [. . . ]
