* As the DC-2 is in AUTOMATIC mode, there may be a brief burst of noise before normal
playback begins.
The DC-2 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-2. 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 automati-
cally loads the 5.1 Logic 7 effect.
The FX ▲ and ▼ 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 recog-
nizes the DTS signal and automatically loads the DTS LOGIC 7 effect*. The
FX ▲ and ▼
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 recog-
nized 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.
