3.6 Changing Volume Level
Push and turn the knob in either direction. The volume can be adjusted even if no
track is playing. When adjusting the volume, the display will temporarily display:
“Volume: XX” where “XX” is a number between 8 (min volume) and 100 (max
volume).
3.7 Changing Selections While Playing
Simply make your new track selection and push the knob (note that if the knob is
not turned for four seconds while you are selecting the new track, the display will
revert to the “PLAYING” screen). The currently-playing audio will fade down and
your new selection will begin. If so configured in CardPrep, the original track will
resume when the new track has finished.
4.0 External Operations
In addition to the front panel controls, the DMP-200 provides several means of remotely
controlling the audio selection and playback.
4.1 Track Selection by External Trigger
The DMP-200 provides three configurable discrete inputs for controlling audio playback
via external switches or sensors. Refer to documentation specific to your installation for
the exact function of each of the external triggers.
Typical applications for external triggering would be aircraft signals such as the “fasten
seat belt” light or dedicated pushbuttons for certain types of briefing announcements or
music. In CardPrep, these three triggers can each be assigned to a speech or music
track, an entire music list, or the “CONTINUOUS MIX” selection.
4.2 Remote PAUSE/PLAY Button
The DMP-200 provides an input which can be used to parallel the pushbutton function of
the front panel knob. An external pushbutton connected to this input will perform the same
function as pushing the front panel knob.
If a track is playing, pushing the remote button will cause playback to pause. Pushing
again will cause playback to resume.
The external pushbutton works in parallel with the front panel knob: playback may be
paused with one and resumed with the other.
If no track is playing, you can turn the front panel knob until a desired track is displayed.
Then, at some later point, you can push the external button to select the displayed track
and to start playback.
The only difference between the external pushbutton and the front panel pushbutton is
that holding the external button down will not cancel playback. Holding the external button
has no effect.
