There's a long road ahead of you, and it definitely needs a soundtrack. That's why Alpine's CDE-9845 CD receiver plays discs loaded with MP3s and WMAs! You can load up to ten hours of music on a single disc, perfect for those times when getting from point A to point B means driving across long stretches of open highway. Alpine's Quick Search function lets you navigate through your folders and files speedily, giving you more time to enjoy the tunes.

Of course, musical variety for its own sake isn't enough for Alpine — it has to sound good, too. Enter Bass Engine® which gives you tight control over the bass and treble output. BBE® sound processing is also on board, which ensures that the lows and highs blend correctly for natural sound reproduction.

System expansion definitely gets its due here, too. If you want to bolster the power output to your speakers and subs, you can connect external amplifiers to the two sets of preamp outputs. Got a portable player, like an iPod? The rear-panel minijack auxiliary input will gladly accept it, giving you even more listening options.

Features

CEA-2006 Compliant: The specifications given by Alpine for the built-in amplifier comply with the CEA-2006 mobile amplifier power testing and measurement standards from the CEA (Consumer Electronics Association). All manufacturers who comply with the standard can display the CEA-2006 logo on their product.

Switchable Button Color: The illumination of the 4 main buttons (Source/Power, Band, |<<, and >>|) can be switched to any of 4 colors: Blue, Green, Amber, and Red. When the illumination is set to Blue or Green, the color of the other buttons is Green. When the illumination is set to Amber or Red, the color of the other buttons is Amber.

Dimmer: This unit is equipped with an illumination dimmer lead. When the unit's dimmer mode has been set to "Auto" and the illumination lead has been connected to your vehicle's headlight circuit, the button illumination will dim to a fixed, preset level whenever the headlights are turned on. If preferred, you may choose the "Manual" dimmer mode setting, so the button illumination is dim at all times.

Bass Engine: Bass Engine functions provide control over your system, so you can tailor the sound to your personal tastes. Bass Engine includes the following functions:

  • Bass Control:
    • Bass Center Frequency: Select from 60Hz, 80Hz, 100Hz, or 120Hz
    • Bass Band Width: Select from 1 (narrow) to 4 (wide)
    • Bass Level: Select from -7 to +10
  • Treble Control:
    • Treble Center Frequency: Select from 7.5kHz, 10kHz, 12.5kHz or 15kHz
    • Treble Level: -7 to +7

BBE: BBE makes vocals or instruments sound distinct regardless of the music source. You can select the level of the BBE effect (1, 2, or 3), or turn BBE off. Note: You can set different levels of BBE for each source. BBE is not available for AM radio.

Switchable Rear/Subwoofer Preout: The rear preamp outputs can be switched to a non-fading subwoofer preamp output with a variable output of 0 to +15. When the subwoofer is activated in the Setup menu, the preout is switched at the same time. When the subwoofer is deactivated, the preout is switched back to a rear channel output.

MP3/WMA Playback: This unit can play CD-ROM, CD-R, and CD-RW discs containing MP3/WMA files recorded using the ISO 9660 Level 1 or Level 2 formats. MP3 files with constant and variable bit rates from 8 kbps to 320 kbps and WMA files with constant and variable bit rates from 48 kbps to 192 kbps are supported. Discs recorded using Joliet, Romeo, or other ISSO 9660 compliant formats can be played, but file and folder names will not be displayed correctly. Discs containing both standard CD audio and MP3/WMA data can be played; the unit may be set to play only the CD audio tracks or both types of tracks. ID3 tag v1 and v2, and WMA tag are supported; track title, artist name and album name ID3 tag data can be displayed.

Disc and Station Titling: Titles of up to 8 characters in length may be entered for up to 24 radio stations and 18 CDs.

Text/File/Folder Search: When you're playing a disc with CD Text, or MP3/WMA tags, you can easily search for a track or file by its title. Once you have activated the search mode, you can use the rotary encoder to quickly scan through the titles to locate the desired track, and select it by pressing the rotary encoder.

Auxiliary Input: The CDE-9845 is equipped with a rear-mounted 3.5mm female mini-jack auxiliary input. In the Setup menu, you can activate/deactivate the Aux Input. When activated, you can choose a name for the input from the following: Auxiliary, TV, VCR, or Game.

Power IC Off: When an external amplifier is connected and the built-in amplifier is not used, removing power from the built-in amplifier will improve the sound quality.

Clock Display Note

Clock Operation: This unit allows you to choose "keyed" or "unit on" clock operation. When the clock has been given display priority and the unit is turned off, the clock will be displayed whenever the ignition key is in the "on" or "accessory" position. If the clock is not given display priority, the clock is not displayed when the unit is off.
