Configuration

PCM Only

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.

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.

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.

NOTE: As DTS is a digital format,

you

must

have a digital input se-

lected for AUDIO IN in the INPUT

CONFIG menu.

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.

NOTE: As AC-3 is a digital format,

you

must

have a digital input se-

lected for AUDIO IN in the INPUT

CONFIG menu.
