Our take on the Alpine CDA-9847 by Crutchfield's Matt Freeman
It's awfully tough to pick out the Alpine CDA-9847 CD receiver's best feature. Is it the dash-enhancing display? The vast number of format options it gives you? And what about the high power amp and extensive sound processing? Wait a minute...maybe it's the combination of all these things that makes this receiver worth crowing about.
Variety is the name of the game with the CDA-9847. Sure it'll play your standard CDs, CD-Rs, and CD-RWs; if you've burned MP3s and WMAs on disc, you can bring them along, too. The Quick Search button lets you scroll through folders and files in a flash, so you find the song you want fast!
The potent internal amplifier (18 watts RMS x 4, CEA-2006 compliant) will rock your speaker system. Alpine's famous Bass Engine® lets you adjust the tone exactly to your liking, while sound-expanding BBE® processing adds focus and impact to all your music. For even more juice, you can send signal to external amplifiers using the three sets of preamp outputs.
This versatile receiver is also compatible with Alpine's KCA-420i iPod adapter. That's right you can control your iPod right from your in-dash receiver. That's simply a mountain of music at your fingertips.
As if all that weren't enough, this powerhouse also features built-in satellite radio controls. Just add a compatible tuner and antenna, and subscribe to your preferred service (XM or SIRIUS), and you've opened up a world of coast-to-coast digital entertaiment, highlighted by over 120 channels of music, news, sports, and entertainment. You may never get out of the car again.
I upgraded my stereo from a KRC 580 to the Alpine CDA 9847. I features are great not to mentioned that it SAT radio ready. I would this receiver to anyone looking to upgrade their head unit.

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-9847. 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.
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.
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.
Subwoofer Output: In addition to front and rear preamp outputs, the CDA-9847 features a dedicated subwoofer preamp output. The subwoofer output has an independent volume control, and can be turned on or off.
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.
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-9847. 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 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.
