About MP3
MP3 (MPEG-1 Audio Layer III) is a standard format for audio compression technology. By
using MP3, a file can be compressed to one-tenth the size of the original.
This unit has limitations on MP3 file standards and recorded media and formats that can be
used. Be aware of the following points when recording MP3 files.
• Supported standards : MPEG-1 Audio Layer III
• Supported sampling frequencies : 32, 44.1, 48 (kHz)
• Supported bit rate : 32, 40, 48, 56, 64, 80, 96, 112, 128 (kbps)
* Supports VBR.
* Does not support free format.
* Bit rates vary for MPEG-1 and MPEG-2.
• Supported channel modes : stereo, joint stereo, dual channel, monaural
MP3 files have an "ID3 Tag" that allows input of information so that data such as song title and
artist can be saved.
This unit supports ID3v.1.0 and ID3v.1.1 tags. Use only ASCII code to record tags, since only
ASCII code is supported by this deck. Recording of characters not included in ASCII code
will result in display of garbled characters.
Media capable of playing MP3 includes CD-ROM, CD-R and CD-RW discs.
Compared to CD-ROM media commonly used for music discs, CD-R and CD-RW discs are
fragile in high temperature/high humidity environments and one section of the CD-R/CD-RW
may become incapable of playback. Fingerprints or scratches on the disc may prevent
playback or cause skipping during playback.
Sections of CD-R/CD-RW may deteriorate if left inside a vehicle for long periods of time.
It is also recommended that CD-R/CD-RW discs be kept in a light-blocking case because the
discs are vulnerable to ultra-violet light.
Playable MP3 file standards
Use 128kbps or lower for the MP3 bit rate. If the bit rate exceeds 128kbps, there
may be sound jumping during MP3 playback.
