MP3/WMA OPERATION

MP3 and WMA (Windows Media Audio) music files are digital audio files

that are compressed to allow more files on a single CD. This unit can play

MP3/WMA directly from files contained on a CD-R/RW using the buttons on

the receiver (or optional remote control) as described below. Many types of

software are available for converting audio files into MP3/WMA formats.

Jensen recommends Nero or Roxio Easy CD Creator. Depending on the

media type and recording method, some CD-R/RWs may be incompatible

with this unit. This unit supports playback of MP3/WMA and CDDA (CDA),

Mixed-Mode CDs and CD-Extra (including multi-session discs). Discs on

which the session has not been closed will not play.
Notes on MP3/WMA Play
This unit can play MP3 (MPEG1, 2, 2.5 Audio Layer 3). However, the MP3

recording media and accepted formats are limited. When writing MP3/

WMA, pay attention to the following restrictions.
Acceptable Media
The MP3/WMA recording media acceptable to this unit are CD-ROM, CD-R

and CD-RW. When using CD-RW, use full format rather than quick format to

prevent malfunction.
Acceptable Medium Formats
The following formats are available for the media used in this unit. The

maximum number of characters used for file name including the delimiter

(".") and three-character extension are indicated in parentheses.

ISO 9660 Level 1 (11 characters)

ISO 9660 Level 2 (31 characters)

Joliet (31 characters)

Romeo (31 characters)

Up to 200 characters can be displayed in the long file name format. For a

list of available characters, see the instruction manual of the writing

software and the section “Entering File and Folder Names” below. The

media reproducible on this unit has the following limitations:

Maximum number of nested folders: 8

Maximum number of files per disc: 999

Maximum number of folders per disc: 255

MP3/WMA files written in formats other than those listed above will not play

successfully and their file or folder names will not display properly.
MP3/WMA Encoder and CD Writer Settings
Use the following settings when compressing audio data with the MP3

encoder.

Transfer bit rate : 8 - 320 kbps

Sampling frequency: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 kHz

When using a CD writer to record MP3/WMA up to the maximum disc

capacity, disable additional writing. To record an empty disc up to the

maximum capacity at once, select the “disc at once” option.
Entering ID3 Tag
This unit supports ID3 tag versions 1.0

and 1.1. For character codes, refer to

the table to the right.
Entering File and Folder Names
Names using the code list characters

are the only file names and folder

names that can be entered and

displayed. Using any other character will

cause the file and folder names to be

displayed incorrectly. The unit

recognizes and plays only files with the MP3/WMA extension.

NOTE: A file name entered with characters not on the code list may
not play correctly.

Writing Files into a Medium
When a medium containing MP3/WMA data is loaded, the unit checks all

data. If the medium contains a large number of folders or non-MP3/WMA

files, MP3/WMA play will be delayed, it may take time for the unit to move to

the next file, and searches may not be performed smoothly. Loading such a

medium may produce loud noise and cause damage to the speakers. Do
not attempt to play a medium containing a non-MP3/WMA file with the
MP3/WMA extension or a medium containing non MP3/WMA files.
