Some words about MP3

The revolutionary new music compression technology MP3 (MPEG Audio Layer-3) enables to shrink down original digital audio sound data with a factor of up to 10 without losing significant sound quality.This allows you to record up to 10 hours of CD-like quality music on a single CD-ROM.

Making your own MP3-CD

Basically there are two sources for MP3 music on CD.You can either create (“rip”) it from your own digital audio CDs or download legal MP3 music from the Internet.

Record (“burn”) the music from your hard disc on CD-ROM with your home PC (make sure filename ends with .mp3). Once finished, you can play your MP3-CD on this set and enjoy the music.

Data rate

The data rate is of great importance with MP3. It indicates how fast bits are transfered.

Stereo music on a CD shows a data rate of about

1400 kilobits per second (kbps). To achieve a good MP3 quality a bit rate of 128 kbps is recommended. As the encoding rate is user-selectable, make sure to reach this data rate for MP3 as recordings less than 128 kbps will suffer from a degradation in sound quality.

Recording

Downloading MP3 files from the Internet or ripping songs from your own digital audio CDs is a delicate process, also influenced by the quality of the encoder program and speed of your PC.This may sometimes result in “drop-outs” which you may experience while listening to your MP3-CD.

In any case make sure to use a recording speed not faster than indicated on the CD-ROM and avoid running other programs simultaneously on your PC during the recording process.

It is not possible to “burn” an MP3-CD on this CD recorder.

It is not possible to record from an MP3-CD.

Supported formats

Following formats are supported on this

CD recorder/changer:

–Disc format: ISO 9660 or Joliet

–Filename: .mp3 (tracks), .m3u or .pls (playlists)

–Bit rate: 32–320 kbps (128 kbps advised) or variable bit rate

Maintenance

Clean the set with a soft, slightly dampened lint-free cloth. Do not use any cleaning agents as they may have a corrosive effect.

Do not expose the set,

batteries or CDs to humidity, rain, sand or excessive heat (caused by heating equipment or direct sunlight).

The lenses may cloud over when the set is suddenly moved from cold to warm surroundings. Playing a CD(RW) is not possible then. Leave the set in a warm environment until the moisture evaporates.

Disc handling

For recording it is very important to use dust and scratch free discs.

To take a CD(RW) out of its box easily, press the center spindle while lifting the CD(RW). Always pick up a

2

CD(RW) by the edge and put it back 1

after use. Never write on a CD or attach a sticker to it. Write only on

the printed side of a CDR or CDRW and only with a soft felt-tipped pen.

To clean a CD(RW), wipe it in a straight line from the center toward the edge using a soft, lint-free cloth. A cleaning agent may damage the disc!

Note: Use the ISO 9660 disc format when burning the CD- ROM. UDF disc format (e.g. ”DirectCD” or “WinOnCD”) is not supported.
