System
Configuration
PCM Only
NOTE: PCM ONLY is automati-
cally selected for an input when-
ever ANALOG is selected as
the AUDIO IN setting, as AC-3
and DTS effects are incompat-
ible 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 ▲ and ▼
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.
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 ▲ and ▼
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.
AC-3 Only
NOTE: As AC-3 is a digital for-
mat, you
must have a digital
input selected for AUDIO IN in
the INPUT CONFIG menu.
DTS Only
NOTE: As DTS is a digital for-
mat, you
must have a digital
input selected for AUDIO IN in
the INPUT CONFIG menu.
