Introduction
Conventional Audio CDs may store and play up to 72 Minutes of Music. By compressing
music with the MPEG-1, layer 3 (in short: MP3) audio coding standard, a storage volume of
up to 12 hours per CD is feasible. OSCAR has been designed as a standalone player for
MP3 compressed audio data. These data can either be stored on a CD-ROM, which can be
played via the built-in CD-Rom drive or on a hard-disk, which can be optionally mounted into
the player’s case. OSCAR is a pure player, it does not contain upload-or recording functions.
The main features are:
•Plays all MPEG-Audio bit rates and sampling (8-48 kHz, 8-320 kbit/s), incl. variable bit
rates, and normal, uncompressed audio CDs.
•Line-out and head phone output.
•Remote control (Infrared)
•RS-232 Interface for activity monitoring and software update
•Built in high quality CD-ROM drive (Toshiba)
•Space for optional 3.5“ hard disk drive
•Supports ISO9660/Joliet und FAT16/32 Filesystem on CD-ROM and hard-disk
•32 bit RISC-Processor for control and Micronas MAS3570D MPEG-Decoder
•Fast forward and fast reverse, variable playing speeds
•Fast access to titels via rotary encoder, title list stored in internal RAM
•Silent 240V power supply, no fan
•Universal usage for home and hobby, background music.
•Shufflemode possible via directories or whole CD-ROM / Hard disk
•Simple preselection of a number of titles (radio mode)
This manual describes set up and operation of the OSCAR player.
Important note:
Unregulated, illegal distribution of MP3-coded, copyright protected music art, especially via
the internet, has become a serious trouble for the music industry. We strongly advice you to
respect the copyright of the artists when using OSCAR to prevent future countermeasures
like copy protection on these data.

Connect the OSCAR via the power cable to a 240V power outlet. The metal case is
connected to ground.
The decoded audio can be delivered to headphones via the headphone connector or fed into
an external power amplifier via the line-out connectors. Active speakers (with built-in
amplifier) may also be connected directly to the line-out connectors. Passive speakers
(without amplifier) may never be directly connected to the line-out outputs.
The RS-232 interface is used for monitoring the activities of OSCAR on an external terminal
or PC. This is mainly intended for diagnosis purposes, a steady connection of a PC to this
interface is not neccessary.
A USB extension is planned as an add-on, your player is already prepared for the USB
extension

Controls
The following drawing shows an overview of the OSCAR controls. They are pretty similar to a
conventional CD-player. All operations are performed via 5 switch buttons and a rotary
encoder with integrated push-down button.
