45 MP3About MP3MP3 (MPEG-1 Audio Layer III) is a standard format for audio compression technology. Byusing 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 beused.Be aware of the following points when recording MP3 files.Playable MP3 file standards•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, monauralID3 tagsMP3 files have an "ID3 Tag" that allows input of information so that data such as song titleand artist can be saved.This unit supports ID3v.1.0 and ID3v.1.1 tags.Use only ASCII code to record tags, sinceonly ASCII code is supported by this deck. Recording of characters not included in ASCIIcode will result in display of garbled characters.MediaMedia capable of playing MP3 includes CD-ROM, CD-R and CD-RW discs. Compared toCD-ROM media commonly used for music discs, CD-R discs are fragile in hightemperature/high humidity environments and one section of the CD-R may becomeincapable of playback.Fingerprints or scratches on the disc may prevent playback or cause skipping duringplayback. Sections of a CD-R may deteriorate if left inside a vehicle for long periods of time.It is also recommended that CD-R discs be kept in a light-blocking case because the discsare vulnerable to ultra-violet light.Use 128kbps or lower for the MP3 bit rate. If the bit rate exceeds 128kbps, theremay be sound jumping during MP3 playback.Caution
