Auto-Loop Playback
After Track 1 is set to play, it will play to the end, then Track 2 will start playing from
beginning to end, then Track 3 etc. When the ProPLAY Audio plays to the end of the
last track, it will automatically jump back to the beginning of Track 1, repeating tracks
1,2 then 3 etc. The ProPLAY Audio will play in auto-loop play mode, so long as none
of the function buttons are pressed. Loop playback is the standard playback setting
of the ProPLAY Audio (in simple play and playlist mode) but the track playback
sequence can be changed as required using ProPLAY Studio software.
4.4 Operating Instructions
There are two operating modes in ProPLAY Audio– “playlist mode” and “simple play
mode”
.
· Playlist mode
When operating in playlist mode, both project file (*.prj) and playlist file (*.pll)
must be present on the Compact Flash card. These are used to control the
sequence for all audio tracks.
The project and playlist file are created using ProPLAY Studio software. Using
this software, you can set simple sequences or complex sequences including
“jump track“ or “next track” actions. ProPLAY Studio can also program buttons
with different function like “play”, “stop”, “pause”, “mute”, “previous”, “next” and
“volume” as well as RS-232 commands to play tracks.
Note: Make sure all capital letters in filename defined in playlist are consistence
with the filename on CompactFlash card. All filename should be in 8+3 format
(i.e. xxxxxxxx.xxx) and avoid using any illegal characters like “~”, “_”, “-“, etc
· Simple play mode
In simple play mode, the user just copies all audio files (.mp3) onto the
Compact Flash card. The ProPLAY Audio will play these files in alphabetical
sequence.
· Schedule play mode
The ProPLAY Audio is able to play back playlists, controlled by date and time
settings. A schedule.ini named file has to be written in the below shown format
and copied onto the CF card. To create the corresponding playlist files,
ProPLAY Studio is required.
