About MP3/WMA

CAUTION Except for private use, duplicating audio data (including MP3/ WMA data) or distributing, transferring, or copying it, whether for free or for a fee, without permission of the copyright holder is strictly prohibited by the Copyright Act and by international treaty. What is MP3?
MP3, whose official name is MPEG-1 Audio Layer 3, is a compression standard prescribed by the ISO, the International Standardization Organization and MPEG which is a joint activity institution of the IEC. MP3 files contain compressed audio data. MP3 encoding is capable of compressing audio data at extremely high ratios, reducing the size of music files to as much as one-tenth their original size. This is achieved while still maintaining near CD quality. The MP3 format realizes such high compression ratios by eliminating the sounds that are either inaudible to the human ear or masked by other sounds.
Search mode is cancelled by pressing and holding 3 /PTY for at least 2 seconds in Folder Name Search mode. While in Folder Name Search mode, press 3 /PTY to switch to File Name Search mode. NO FILE is displayed for 2 seconds if the folder that is selected by the Folder Name Search mode contains no files. ROOT is displayed for a folder that does not have a folder name. Folder Name search cannot be made during M.I.X. play.

File Name Search mode

Press 19/AF or 28/NEWS to select another Folder. Select the desired file by turning the Rotary encoder (CDE-9845RX) or press 4 and 3 (CDE9843RX) within 10 seconds. Press the Rotary encoder (CDE-9845RX) or MODE/LOUD (CDE-9843RX) to play back the selected file.

What is WMA?

WMA, or Windows Media Audio, is compressed audio data. WMA allows you to create music files and store them at higher ratios of compression than MP3 audio data (approx. half original size). This is achieved while still maintaining CD quality sound.

File Name Search mode is cancelled by pressing and holding 3 PTY for at least 2 seconds. While in File Name Search mode, press 3 /PTY to switch to Folder Name Search mode. File Name search cannot be made during M.I.X. play.
Method for creating MP3/WMA files
Audio data is compressed by using MP3/WMA specified software. For details on creating MP3/WMA files, refer to the user's manual for that software. MP3/WMA files that can be played back by this device have the file extension mp3 / wma. Files with no extension cannot be played back. (WMA ver. 7.1, 8 and 9 are supported)
Supported playback sampling rates and bit rates
MP3 Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 16 kHz, 12 kHz, 11.025 kHz, 8 kHz Bit rates: 8 - 320 kbps Variable Bit rate: 8 - 320 kbps WMA Sampling rates: 48 kHz, 44.1 kHz, 32 kHz Bit rates: 48 - 192 kbps Variable Bit rate: 48 - 320 kbps Note that for sampling rates, this devices frame display (Page 16) may not display correctly. This device may not play back correctly depending on sampling rates.

Order of files

The unit plays the files in the order that the writing software writes them. Therefore, the playing order may not be the same as the order you input. The playback order of the folders and files is as follows. However, the folder and file playback order differs from the folder no. and file no. indicated on the display.

Root folder

ID3 tags/WMA tags
This device supports ID3 tag v1 and v2, and WMA tag. If tag data is in an MP3/WMA file, this device can display the title (track title), artist name, and album name ID3 tag/WMA tag data. This device can only display single-byte alphanumeric characters (up to 30 for ID3 tags and up to 15 for WMA tags) and the underscore. For non-supported characters, NO SUPPORT (CDE-9845RX only) or NO SUPRT (CDE-9843RX/ CDE-9841R only) is displayed. The tag information may not be correctly displayed, depending on the contents.

Producing MP3/WMA discs

MP3/WMA files are prepared, then written to a CD-R or CDRW using CD-R writing software. A disc can hold up to 510 files/folders (including Root Folders). However, the maximum number of folders is 255.

Media supported

The media that this device can play back are CD-ROMs, CDRs, and CD-RWs.

Terminology

Bit rate This is the sound compression rate specified for encoding. The higher the bit rate, the higher the sound quality, but also the larger the files. Sampling rate This value shows how many times per second the data is sampled (recorded). For example, music CDs use a sampling rate of 44.1 kHz, so the sound is sampled (recorded) 44,100 times per second. The higher the sampling rate, the higher the sound quality, but also the larger the volume of data. Encoding Converting music CDs, WAVE (AIFF) files, and other sound files into the specified audio compression format. Tag Song information such as track titles, artist names, album names, etc., written into MP3/WMA files. MP3: ID3 tag WMA: WMA tag Root folder The root folder is found at the top of the file system. The root folder contains all folders and files.
Corresponding File Systems
This device supports discs formatted with ISO9660 Level 1 or Level 2. Under the ISO9660 standard, there are some restrictions to remember. The maximum nested folder depth is 8 (including the root directory). The number of characters for a folder/file name is limited. Valid characters for folder/file names are letters A-Z (all caps), numbers 0-9, and _ (underscore). This device also can play back discs in Joliet, Romeo, etc., and other standards that conform to ISO9660. However, sometimes the file names, folder names, etc., are not displayed correctly.

Formats supported

This device supports CD-ROM XA, Mixed Mode CD, Enhanced CD (CD-Extra) and Multi-Session. This device cannot correctly play back discs recorded with Track At Once or packet writing.

Avoid installing the unit in locations with high incidence of moisture or dust. Moisture or dust that penetrates into this unit may result in product failure.
DO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND CONNECTIONS.
Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc.

Precautions

Be sure to disconnect the cable from the () battery post before installing your CDE-9845RX/CDE-9843RX/CDE-9841R. This will reduce any chance of damage to the unit in case of a shortcircuit. Be sure to connect the colour coded leads according to the diagram. Incorrect connections may cause the unit to malfunction or damage to the vehicle's electrical system. When making connections to the vehicle's electrical system, be aware of the factory installed components (e.g. on-board computer). Do not tap into these leads to provide power for this unit. When connecting the CDE-9845RX/CDE-9843RX/ CDE-9841R to the fuse box, make sure the fuse for the intended circuit of the CDE-9845RX/CDE-9843RX/CDE9841R has the appropriate amperage. Failure to do so may result in damage to the unit and/or the vehicle. When in doubt, consult your ALPINE dealer. The CDE-9845RX/CDE-9843RX/CDE-9841R uses female RCA-type jacks for connection to other units (e.g. amplifier) having RCA connectors. You may need an adaptor to connect other units. If so, please contact your authorized ALPINE dealer for assistance. Be sure to connect the speaker () leads to the speaker () terminal. Never connect left and right channel speaker cables to each other or to the vehicle body.
DO NOT INSTALL IN LOCATIONS WHICH MIGHT HINDER VEHICLE OPERATION, SUCH AS THE STEERING WHEEL OR GEARSHIFT.
Doing so may obstruct forward vision or hamper movement etc. and results in serious accident.
