For all entertainment needs, the MP903 mobile player is a high capacity music box which broadcasts music organised in directories. Stand-alone and functioning offline, the MP903 player is as easy to use as a CD player, without the hassle of carrying, handling, storing and replacing CDs.
The whole music library is readily available by selection from a fingertip.
A LCD displays name, length and remaining time of the current track. At any time, it is possible to select a specific track or directory using the forward and back keys.
Three control panels provide the necessary interface and controls to the operator:
1 - Transport bar 8 keys (read - stop - next rack - previous track, options …)
2 - 10 digital keys allow track selection - key in the file number
3 - 9 pre-set keys to access directly to specific music styles
The analog audio interface offers talk over facility, bass and treble adjustment, one auxiliary input to connect an external source and headphone socket.
