Entertainment Systems MP3 DISC QUALITY FACTORS The MACH MP3 music system is designed for use with CD-DA (regular audio discs), CD-R and CD-RW discs. Discs must comply with ISO 9660 and Joliet standards. Several factors can effect disc playback quality: • Disc capacity - Each disc contains about 650 MB of storage capacity. We do not recommend using high capacity discs containing 700MB of storage. • Disc type - Some CD-RW discs may operate inconsistently and may cause an error message to appear. We recommend burning MP3 files onto CD-R discs. • Disc finalization - The disc may be left open for the purpose of adding sessions to it at a later time, but be sure to close each session or the disc will not play. • Bit rate - The player supports bit rates from 56-320 kbps, as well as variable bit rate MP3 files, but lower bit rates will have a noticeable effect on sound quality and are recommended only for speech or low fidelity music material. We recommend that you encode MP3 files using a high quality encoder. • PC configuration - Encoding MP3 files requires intensive use of your computer's resources. Follow the PC configuration recommendations of the encoder software vendor. We recommend that you avoid running other software applications on your PC during MP3 encoding to avoid undesirable noise and distortion. CD, MP3 AND CD PLAYER CARE • Handle discs by their edges only. Never touch the playing surface. • Do not expose discs to direct sunlight or heat sources for extended periods of time. • Do not insert more than one disc into the slot of the CD player (if equipped). • Always store discs out of direct sunlight. Excessive heat may damage or warp discs. • Use care when handling and playing CD-R and CD-RW discs, which are more susceptible to damage from heat, light and stress than are regular CDs. • Always insert and remove a disc by holding the disc flat, with the playing surface facing down, in order to prevent damage to the disc or the player. 65
