9. LCD display:

This graphic blue LCD-display shows a lot of information. The information shown depends

on which input is selected.

10. USB-input:

here you can connect all kinds of USB-memories (USB-sticks, USB-hard disks, …). As soon

as the memory device is inserted, the display shows “Searching”, next the first track will be played.

Some important notes:



The USB-memory should be formatted in FAT16 or FAT32 (most USB-sticks and small hard
disks are OK, however bigger hard disks are formatted in NTFS)



Using a hard disk with external power supply is preferred, the USB-output on the MPL-1 is not
always able to supply enough current to the external hard disk.

here you can connect MMC, SD and SDHC memory

cards, formatted in FAT16 / FAT32. Insert the memory card until you
