04 239 The MP3 format, an abbreviation of MPEG 1.2 & 2.5 Audio Layer 3, is an audio compression standard which permits the recording of several tens of music fi les on a single disc. In order to be able to play a recorded CDR or CDRW, when recording, the ISO 9660 level 1.2 or Joliet fi le format is recommended. If the disc is recorded in another format, it may not be played correctly. It is recommended that the same recording format is always used for an individual disc, with as low a speed as possible (4x maximum) for optimum sound quality. In the particular case of a multi-session CD, the Joliet format is recommended. The audio system will only play fi les with the extension ".mp3" with a sampling rate of 22.05 KHz or 44.1 KHz. No other type of fi le (.wma, .mp4, .m3u...) can be played. It is advisable to restrict fi le names to 20 characters without using special characters (e.g. " ? ; ù) to avoid any playing or displaying problems. MP3 CD Information and advice AUDIO Empty CDs are not recognised and may damage the system. Insert an MP3 compilation in the player. The audio equipment searches for all of the music tracks, which may take anything between a few seconds and several tens of seconds, before play begins. MP3 CD Playing an MP3 compilation On a single disc, the CD player can read up to 255 MP3 fi les spread over 8 folder levels. However, it is advisable to keep to a limit of two levels to reduce the access time before the CD is played. While the CD is being played, the folder structure is not followed. All of the fi les are displayed on a single level. To play a disc which has already been inserted, press the SOURCE button several times in succession and select CD. Press one of the buttons to select a folder on the CD. Press the LIST REFRESH button to display the list of directories of the MP3 compilation. Press and hold one of the buttons for fast forward or backward play. Press one of the buttons to select a track on the CD. |
