P/N DMP020 V1.8
Overview
The DMP-300 Digital Media Player is a self-contained unit which stores and replays pre-
recorded audio tracks. The audio tracks are encoded in “Motion Picture Expert Group
(MPEG) Level 3” format, commonly referred to as “MP3”. Audio files are stored in a
removable CompactFlash™ memory card which is prepared and installed by the user.
Audio tracks are selected via a single rotary pushbutton on the front panel of the DMP-
300. Optionally, the DMP-300 may be connected to a maximum of seven external
discrete trigger inputs, each of which can be configured in software to select a particular
audio track. In addition, the RS232 data from a panel-mount GPS may be connected to
the DMP-300 to allow triggering of audio files based on geographic position.
The DMP-300 memory card must be prepared using CardPrep software, which is
provided with the DMP-300 and may also be downloaded from the Avionics Innovations
website at www.avionicsinnovations.com. CardPrep is a Windows application which
assembles your desired MP3 files into the DMP-300 format, and allows you to specify
attributes such as language or trigger information.
The DMP-300 memory card can contain up to 500 individual MP3 audio files. Speech
files can be organized into as many as 16 languages, and music files can be organized
into as many as 127 music lists. Total audio capacity is determined by the memory size of
each card. In general, a DMP-300 memory card will hold approximately one minute of
sound per megabyte of memory at CD-quality data rates.
CardPrep gives you control over many aspects of DMP-300 operation. You can:
♦Display a custom two-line message on power up
♦Automatically play a selected speech track on power up, which will then play once
for each language enabled (also selectable)
♦Automatically play a selected music track, an entire music list, or a continuous
random mix of all music tracks on power up
♦Attach a discrete or GPS trigger to any audio track, music list, or “continuous mix”
♦Designate any music track to be played as a continuous loop
♦Designate, for each track, whether or not it should resume playing after it is
interrupted by a new play command
♦Designate, for each track, whether it is played at the normal volume level or at a
pre-determined “LOUD” setting. This allows background music to play at a quiet
volume setting, while important safety messages are played at a higher level.
♦Select whether or not a chime is sounded between each language of a speech
track
♦Select whether the DMP-300 sounds an external chime for speech tracks or
whether it plays a specified MP3 file (two different MP3 recordings of chime
sounds are provided).
All configuration data is contained on the memory card, and can be changed by simply
inserting a different card. Each card also contains the latest version of DMP-300 firmware,
which is automatically loaded by the unit if needed.
