Digital music playback, customizable controls, system expansion options, and great looks — Alpine's CDA-9851 CD player has it all.

This receiver's versatility is tough to beat. In addition to your standard CDs, it'll play MP3 and WMA files you've burned on a CD-R or CD-RW (up to 10 hours of music on one disc). Alpine also included Bass Engine® tone controls for sound shaping at its finest. Meanwhile, BBE® sound processing cleans up the sound for pristine delivery. Your music, no matter the format, will always sound spectacular.

The on-board amplifier delivers a stout 18 watts RMS (x four channels) to power your music. If you'd like even more gusto, you can add a full complement of amplifiers to the three sets of preamp outputs.

It's also compatible with Alpine's iPod ™ control interface, which lets you control your iPod right from the receiver (the adapter also charges your iPod's battery). Built-in satellite radio controls mean you can add a compatible XM or SIRIUS tuner (plus antenna and subscription) and enjoy over 120 channels of music, news, talk, sports, entertainment and more.

Note: Although the i-Personalize logo appears on the CDA-9851's faceplate, the player does not have this feature.

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.

Satellite Radio Ready: There are several options for connecting an optional XM or Sirius Satellite Radio receiver to the CDA-9851. To receive XM Satellite Radio, you can connect the optional Terk XMD1000 Universal tuner (209XMD1000) and the Terk XM Direct Smart Digital Adapter for Alpine (209XMDALP1). To receive Sirius Satellite Radio, you can connect the optional Sirius tuner for Alpine (item # 607SIRALP1) directly to the head unit. A portable satellite radio receiver, such as the Delphi SkyFi or Sirius Sportster, can be connected to the head unit via an auxiliary input adapter. A compatible antenna and a subscription are also required to receive satellite radio programming from Sirius or XM.

SwingFace Mechanism: The CDA-9851's SwingFace mechanism provides an extra large multi-colored display area for ease of viewing. The motorized faceplate not only slides down to let you insert or eject CDs, but gives you a choice of three viewing angles or fully closed.

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 display and 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 display and 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

Subwoofer Output: In addition to front and rear preamp outputs, the CDA-9851 features a dedicated subwoofer preamp output. The subwoofer output has an independent volume control, and can be turned on or off.

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.

Interrupt Feature: When a device having the interrupt feature (such as a cellular telephone) is connected to the receiver, the audio signal will be automatically muted whenever the interrupt signal is received from the device. The supplied wiring harness contains a pink Interrupt lead that needs to be connected to the device's interrupt signal connection.

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 tags v1 and v2, and WMA tags 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 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.

Frequency Search: In the tuner mode, you can easily and quickly tune to a desired station by performing a frequency search. When Frequency Search is activated, you can "dial" in the frequency using the Rotary Encoder.

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.

Remote Control: The receiver comes with the RUE-4202 wireless remote control. The remote can control volume, source selection, tuner and disc functions, as well as CD changer controls.

Steering Wheel Remote Compatibility: The CDA-9851 has a "steering remote control" input on the back panel. When used with the optional SWI-ALP interface (item #127SWIALP), you can retain the use of your factory steering wheel and/or rear seat radio controls when replacing the factory head unit in select vehicles. The SWI-ALP is compatible with over 95% of the vehicles made from 1986 to the present. Compatible vehicles include many Acura, Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Honda, Hummer, Infiniti, Isuzu, Jaguar, Jeep, Kia, Land Rover, Lexus, Lincoln, Mazda, Mercury, Mini, Mitsubishi, Nissan, Oldsmobile, Plymouth, Pontiac, Saab, Saturn, Suzuki, Toyota, and Volkswagen vehicles and Harley Davidson motorcycles. Please consult "What Fits My Car" to see if your vehicle is compatible.

CD Changer Controls

Ai-NET Compatible: An optional Ai-NET-compatible 6- or 12-disc CD changer (including MP3 Changers) may be connected to, and controlled by, the CDA-9851. With the KCA-410c Versatile Link Terminal (item # 500KCA410C), you can control multiple changers with this unit.

iPod-Ready: An iPod or iPod Mini can be controlled from this unit when connected via the KCA-420i Alpine Interface Adapter for iPod (item # 500KCA420i). While connected to the head unit, the iPod's battery is charged, and the artist/song title information is displayed on the face of the head unit. The unit's Quick Search feature allows you to search by playlist, album name, artist name, or song title. Random and repeat play functions are also available.

Optional Auxiliary Input: With the optional KCA-121B Ai-NET/RCA interface cable or KCA-410C Versatile Link Terminal, you can input audio from an auxiliary source unit, such as a TV, VCR or portable unit.

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.
