If you store music on your computer, Alpine's CDA-9811 CD receiver will play MP3 and Windows Media (WMA) files that you've recorded on CD-R or CD-RW — and the song titles are showcased nicely by the large, multicolor display. The built-in MOSFET amplifier will bring all your tunes to life with 23 watts RMS power. If you're building a system, use the three sets of 4-volt preamp outputs to channel signal to your outboard amps.

Alpine's Media Xpander™ feature restores sparkle to music that's been broadcast or compressed — it does wonders for your MP3 and WMA files. Bass Engine® Plus combines a 2-band parametric equalizer, 4-channel digital time alignment, and a 3-position crossover so you can refine the sound until it's as smooth as butter. You can even use the i-Personalize™ feature on Alpine's website to figure out the time correction settings for your vehicle. The website gives you the numbers to enter into your receiver for perfect positioning of the musical "sweet spot."

Put 6 or 12 discs at your command by adding an Alpine CD changer, or use the optional auxiliary input to connect any outboard audio source. Radio fans will appreciate the station-pulling power of the MaxTune SQ AM/FM tuner. Or, hook up an Alpine XM Satellite Radio tuner (XM antenna and subscription also required), and gain coast-to-coast access to over 100 channels of music, sports, news, and entertainment.

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Features

Selectable Faceplate Angle: In addition to the standard faceplate position, there are three preset faceplate angles for you to choose from.

Blackout Display Mode: When the Blackout mode is activated, the display turns off to reduce power consumption. The additional power made available by turning off the display helps enhance sound quality.

Audio Level Display: This unit has one audio signal level display pattern, which can be turned on or off.

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

  • 4-Channel Digital Time Correction: The time correction feature allows you to create virtual speaker positions by delaying the signals being sent to the speakers closest to you. When the correct delay times have been entered for the front right, front left, rear right and rear left speakers, all sounds reach your ears at the same time, providing optimized imaging and frequency response.
  • 3-Position 12dB/Octave Crossover: An 80Hz/120Hz/160Hz low-pass filter is available for the subwoofer outputs, and an 80Hz/120Hz/160Hz high-pass filter is available for the front right, front left, rear right and rear left preamp outputs. Either, or both, filters may be turned off.
  • MX (MediaXpander): The MediaXpander function makes vocals or instruments sound distinct by restoring sound quality typically lost during recording or transmission; this function helps restore audio information that becomes obscured when audio is compressed. The MX function can be applied to all sources, except AM radio. There are three expansion modes for each internal source (CD, FM, MP3/WMA/XM), and each source can have its own setting. There are also three expansion modes available for external sources.
  • Bass Center Frequency Control: To tailor bass response to your preference, you may select the bass control's center frequency. You may select from the following center frequencies: 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 130Hz, 150Hz, or 200Hz.
  • Bass Width Control: You may choose from four band width (Q-Factor) settings for the bass control; the bass control can be set to affect a wide or narrow band of frequencies.
  • Bass Type: You may choose from the following Bass Type settings: Type 1, Type 2, or Type 3. Type 1 will sound best if you have a subwoofer in your system. Use Type 2 or Type 3 if you are using small diameter speakers.
  • Treble Center Frequency Control: To tailor treble response to your preference, you may select the treble control's center frequency. You may select from the following center frequencies: 10kHz, 12.5kHz, 15kHz, or 17.5kHz.
  • Subwoofer Level Control: The level of the subwoofer preamp outputs can be adjusted to balance the output of your subwoofer with that of your other speakers.
  • Subwoofer Phase Selector: The phase of the subwoofer outputs may be set to normal (0 degrees) or reverse (180 degrees); this function allows you to minimize phase cancellation of bass frequencies, for stronger bass response.

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 32 kbps to 192 kbps are supported. Discs recorded using Joliet or other ISSO 9660 compliant formats can be played, but file and folder names will not be displayed correctly. CD-ROM XA, Mixed Mode CD, Enhanced CD (CD-Extra) and multi-session recordings are supported, but recordings made using Track At Once or packet writing cannot be correctly played back. 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 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.

XM Radio Ready: An optional XM Satellite Radio tuner may be connected to, and controlled by, this unit. The optional tuner, along with an antenna and subscription, allows you to receive XM Satellite Radio. XM Satellite Radio programming features up to 100 channels of digital-quality music, news, talk, sports, entertainment, and children's programming.

Auxiliary Input Ready: With the addition of the optional KCA-121B Ai-NET/RCA interface cable, the KCA-801B auxiliary input adapter, or the KCA-410C Versatile-Link Terminal, the audio from an auxiliary source can be played through this unit. When the KCA-121B interface cable is used, a CD changer cannot be connected to the head unit; the KCA-801B auxiliary input adapter allows you to connect an auxiliary source and an Ai-NET changer to the head unit. The KCA-410C Versatile-Link Terminal allows you to feed audio from up to two auxiliary sources and two Ai-NET CD changers to the head unit.

MobileHub Link: Using the MobileHub Link, you can connect an optional Junction Box and a Nokia 6310i tri-band GSM cellular phone, allowing you to control the incoming and outgoing calls from the head unit. 

Changer Controls

Compatibility: This unit is compatible with 6- and 12-disc Alpine Ai-NET CD changers; also, this unit can control Alpine Ai-NET CD/MP3 changers and DVD changers. Alpine M-Bus CD changers cannot be controlled by this unit. 

Multiple Changer Control: With the addition of an optional adapter, more than one CD changer can be controlled. One KCA-400C adapter will allow you to connect up to 4 CD changers, and two KCA-400C adapters will allow you to connect up to a total of 6 CD changers. The KCA-410C Versatile-Link Terminal can be used to connect up to two CD changers and two auxiliary audio sources.

Text Display: When connected to a text capable changer, this unit can display text data from CD Text encoded CDs and MP3 CDs.

Disc Titling: When connected to a CD changer with disc title memory, CD titles may be entered and displayed for discs played in the changer. The title length and title capacity varies depending on the model of CD changer used; titles cannot be input for MP3 discs.

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.
