Explanation of terms

Getting started

Bit rate

This expresses the read amount per 1 second of video/audio data recorded in a disc.

MP3 (MPEG Audio Layer-3)

This is an internationally standardized audio data compression scheme, using the “MPEG-1” video compression standard. It compresses the data volume to about one eleventh its original size while maintaining sound quality equivalent to a music CD.

Sampling frequency

Sampling involves taking a reading of a sound wave (analog signal) at regular intervals and expressing the height of the wave at each reading in digitized format (producing a digital signal).

The number of readings taken in one second is called the “sampling frequency”. The larger the value, the closer the reproduced sound is to the original.

WMA (Windows Media Audio)

This is audio compression technology developed by Microsoft Corporation.

WMA data can be encoded using Windows Media® Player Ver.7, 7.1, Windows Media® Player for Windows® XP and Windows Media® Player 9 Series.

To encode WMA ﬁles, only use applications authorized by Microsoft Corporation. If you use an unauthorized application, the ﬁle may not work properly.

Others

nPlaying CD-R/CD-RW discs

This unit can play back the CD-RW (ReWritable) discs as well as ordinary Audio CD and CD-R (Recordable) discs.

•This unit can play back Audio CD format and CD-R/CD-RW discs which contain MP3/WMA music data. However, some discs may have problems such as unable to play, noise or sound distortion. For details, please read the instruction manual provided with a CD recorder.

•The CD-R and CD-RW discs should contain properly-recorded TOC information so that they can be played back. In CD recorders, the task of writing TOC information is referred to as ﬁnalizing the disc. Discs that are not ﬁnalized cannot be properly recognized as an Audio CD and played back by regular CD players and Super Audio CD players. For details, please read the instruction manual provided with a CD recorder.

*TOC stands for Table Of Contents and contains information such as the total number of tracks and total playing time of the disc.

•This player can only be used to play Audio CD-DA format discs or discs on which MP3 or WMA audio data have been recorded. Do not attempt to play a disc containing other data, such as a CD-ROM for PCs, on this unit.

•As the playback of a CD-RW disc necessitates partial change of the player setup, it may take longer time for reading the TOC information than when an Audio CD or CD-R disc is played.

nPlaying MP3 or WMA ﬁles

This CD player can be used to play CD-R or CD-RW discs on which MP3 (MPEG Audio Layer-3) or WMA (Windows Media Audio) format audio ﬁles have been recorded.

Support for MP3 ID3 tags enables display of ID3 information, such as artist names, album titles, track titles and the like, if this information has been recorded with the tracks.

•Windows Media and the Windows are the registered trademark and trademark of Microsoft Corporation in the United States and other countries.

•Music that you have recorded that is subject to copyright laws is for personal use only, and cannot be used otherwise without the permission of the copyright holder.

NOTE

•The sound ﬁle speciﬁcation supported by this CD player is “MPEG-1 Audio Layer-3” (sampling frequency fs 32 kHz, 44.1 kHz, 48 kHz). Other speciﬁcations, such as MPEG-2 Audio Layer-3, MPEG-2.5 Audio Layer-3, MP1 or MP2 are not supported.

•Generally the higher the bit rate, the higher the sound quality.

MP3 bit rates are between 32 - 320 kb/s and for WMA between 64 - 160 kb/s. It is recommended that MP3/WMA recordings with a bit rate of at least 128 kb/s be used.

•Ensure that MP3/WMA ﬁles have the extension “.mp3” or “.wma.” Files with other ﬁle extensions or without any extension at all cannot be played on this player.

•Playlists are not supported.

•The maximum number of ﬁles supported on a single disc is 255 and the maximum number of folders is also 255.

•File and folder names up to a length of 32 characters can be displayed.

•This player supports MP3 ID3 tags.

•The text information, such as ID3 tag information and ﬁle names that are displayed during playback of MP3s, support English alphanumeric characters only.

•When playing variable bit rate ﬁles, it is possible that the playing time may not be displayed accurately.

•When writing onto CD-R or CD-RW discs, please use either ISO9660 mode 1 or ISO9660 mode 2-disc format. Multi-session recording is also supported enabling the playing of data that have been added to a disc.

•MP3/WMA ﬁles that have been recorded by “packet writing” cannot be played back.

•Depending on the condition of the recorded data, it may take some time to read song information.

•In the case of an Enhanced or Mixed Mode CD having combined audio format CD-DA along with MP3/WMA ﬁles, only the CD-DA audio portion will be played.

•The playback of WMA DRM (Digital Rights Management) ﬁles is not supported by this player.
