MP3/WMA Operation

MP6612i

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, SD card or USB device 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 SD card, USB hard drive or flash drive, 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.
