Lexicon MC-1 owner manual PCM Only, AC-3 Only, DTS Only

MC-1 Digital Controller

PCM Only

System Configuration

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 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.

NOTE: As AC-3 is a digital format, you must have a digital input se- lected for AUDIO IN in the INPUT CONFIG menu.

AC-3 Only

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 ▲ 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 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.

NOTE: As DTS is a digital format, you must have a digital input se- lected for AUDIO IN in the INPUT CONFIG menu.

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 ▲ and

▼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.
