General Information
The Becker Digital Player DP4100 is an audio playback system for
passenger information, safety instructions or music to be used in aircraft
cabin environments.
It can act like a standard CD-player (music entertainment) or an
announcement system with a display based user guidance.
The audio tracks (music or announcements) are stored by using a
special file and folder structure on standard PCMCIA flash memory cards
which are inured for vibration or mechanical shocks. The MPEG2 Layer3
(MP3) file format is used to ensure an easy and up to date handling. By
this, standard tools can be used for recording of new announcements or
music.
The file and folder structure on the used memory card decides the kind
of operation of the DP4100. There are 2 types of cards supported:
- “Music-Card” The DP4100 acts like a CD-player.
- “Announcement-Card” The DP4100 acts as an announcement
system.
The “Music-Card” can be used to playback up to 999 music tracks from
one memory card. The number of tracks which can be stored on a card
depends to the available memory size and the used bitrate.
With an “Announcement-Cards”, the DP4100 supports up to 99 missions
stored on a card.
The DP4100 supports ATA-Flash-Cards with a memory space up to
2GByte. The used standard for the cards is the PCMCIA PC-Card type.
With an adapter available by third parties, Compact Flash Cards can be
used as well.
The ATA-Norm ensures that the memory cards can be read and written
with a standard personal computer. Please advise that the file naming
must be in accordance to the DOS constraints which means up to 8
chars for the name and up to 3 chars for the file extension.
For preparation of cards to be used inside the DP4100 system, a special
software tool running on standard personal computers is available. This
tool is delivered on a CD-ROM which also contents the system and
software manuals.

Page 6 of 28 Issue 04/2005
CAUTION
The DP4100 operates with ATA-flashcards only. SRAM cards
or other memory card standards will not be accepted.
For retrofit reasons, the DP4100 is pin compatible with the TP3100
analog audio tape player provided by BECKER in the past.
The DP4100 supports several interfaces for flexible system integration in
a wide range of fixed and rotary wing aircraft.
