[. . . ] Owner's Manual DC-1 Digital Controller Version 3 Dolby Digital® and DTS® Versions 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. [. . . ] This change is recognized by the DC-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). When playback is resumed, the DC-1 automatically reselects the DTS MUSIC effect. To go back to the effect selected as a default, simply press the input button. * As the DC-1 is in AUTOMATIC mode, there may be a brief burst of noise before normal playback begins. 18 DC-1 Version 3 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-1 can be used. When the DC-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 DC-1 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-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 DC-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 DC-1 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-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 DC-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 DC-1 would have muted briefly rather than automatically selecting the PCM effect Logic 7. DTS Only (DTS Version 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-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 availble for AUDIO IN are: ANALOG, COAX (1-2) and OPTICAL (1-2). Analog When ANALOG is selected for a given input, the DC-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 1-2 and OPTICAL 1-2 (Digital Audio Inputs) When one of these four digital inputs is selected, the DC-1 will use it to derive the signal for the MAIN OUTPUTS. Note that all four digital inputs can be used for various DC-1 inputs. This is particularly useful when using source components such as a laser disc or a DVD player to drive multiple DC-1 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. The inputs labeled VCR1, VCR2, 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 VCR1 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. 20 DC-1 Version 3 Digital Controller System Configuration 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. [. . . ] Turn the master power switch on the DC-1 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-1 LCD displays normally at the end of this test, no problems have been found with the DC-1 circuitry. If the internal tests fail, the LCD may display an error message, or no message at all.
