MP3 DISC QUALITY FACTORS
The MACH
威
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.
