[. . . ] Owner's Manual DC-2 Digital Controller Important Safety Instructions Save these instructions for later use. Follow all instructions and warnings marked on the unit. Always use with the correct line voltage. Refer to the manufacturer's operating instructions for power requirements. [. . . ] The DC-2 identifies the signal as PCM and automatically loads the LOGIC 7 effect (as specified in the INPUT CONFIG menu). Now, assume the movie is replaced with one that is encoded in Dolby Digital (AC-3). When it begins to play, the LDD-1 recognizes the signal as being AC-3 encoded and demodulates it for the DC-2. The DC-2 automatically loads the 5. 1 Logic 7 effect. The FX v and w 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. 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). Because the laser disc is paused, there is no audio. 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. To go back to the default effect, simply press the input button. 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). Because the disc player is searching, there is no audio. 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. [. . . ] Turn the master power switch on the DC-2 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-2 LCD displays normally at the end of this test, no problems have been found with the DC-2 circuitry. If the internal tests fail, the LCD may display an error message, or no message at all.
