The CDE-9870 CD receiver plays MP3 discs, includes a strong built-in amplifier, and features a detachable face for added security. Just add Alpine's optional "Full Speed" connection cable to gain fast, complete access to your iPod®. The percentage search feature lets you find your music files quickly: each of the six radio preset buttons jumps over a designated percentage (0, 17, 33, 50, 67, or 83 percent) of your playlist.

Instead of normal bass and treble controls, the Bass Engine® feature lets you select which bass and treble frequencies you want to adjust, so that you can do a better job of tuning the sound. Connect a powered subwoofer to the set of preamp outputs, and Bass Engine also lets you adjust the bass level from the stereo. Alpine goes a step further by including a high-pass filter to block the low bass that your regular speakers can't handle.

    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 Consumer Electronics Association. All manufacturers who comply with the standard can display the CEA-2006 logo on their product.

    MP3 Playback: This unit can play CD-ROM, CD-R, and CD-RW discs containing MP3 files recorded using the ISO 9660 Level 1 or Level 2 formats. Constant and variable bit rates from 8 kbps to 320 kbps are compatible. Discs recorded using Joliet, Romeo, or other ISO 9660 compliant formats can be played. Discs containing both standard CD audio and MP3 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.

    Text/File/Folder/Playlist/Artist/etc Search: When you're playing a disc with CD Text or ID3 tags, or playing a connected iPod, you can easily search for a track, file, folder, playlist, album, artist, etc by its title. Once you have activated the search mode, you can use the volume control to quickly scan through the titles.

    Sound: The Sound Setting functions provide control over your system, so you can tailor the sound to your personal tastes:

    • Bass Control:
      • Bass Center Frequency: 60Hz, 80Hz (default), 100Hz, or 200Hz
      • Bass Band Width: 1 (narrow) to 4 (wide)
      • Bass Level: -7 to +7 (+/-14dB in 2dB steps)
    • Treble Control:
      • Treble Center Frequency: 10kHz (default), 12.5kHz, 15kHz, or 17.5kHz
      • Treble Level: -7 to +7 (+/-14dB in 2dB steps)
    • High Pass Filter (HPF): speaker level outputs have a selectable crossover (HPF); off (default), 80Hz, 120Hz, or 160Hz
    • Loudness: on/off
    • Defeat On/Off: reset the unit to its factory default bass, treble, loudness, and HPF settings by turning on the Defeat function

    Switchable Pre-out: The preamp outputs can be switched from front channel outputs to a non-fading subwoofer preamp output with a variable level of 0 to +15. When the subwoofer is activated in the Setup menu, the pre-out is switched at the same time. When the subwoofer is deactivated, the pre-out is switched back to a front channel output.

    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 that device. The supplied wiring harness contains a pink/black Interrupt lead that needs to be connected to the device's interrupt signal connection.

    Dimmer: This unit is equipped with an illumination 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.

    Power IC Off: When an external amplifier is powering all the speakers in the system, you can turn the internal amp off, which will improve the sound quality.

    Angle Mounting: Alpine recommends mounting the CDE-9870 no more that 35° above horizontal.

    External Device Controls

    iPod Full Speed: The CDE-9870 has an iPod Direct Connection mounted on a 6" pigtail on the rear panel. When used with the optional KCE-422i Alpine Full Speed Connection cable (item number 500KCE422i), your receiver can interface with Apple iPods with a dock connector, fourth generation and newer. You can quickly and easily search through all of the music contained on your iPod through Playlist, Artist, or Album searches. You can view Artist, Album, Song Information and Song Number right on the head unit's display.

    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.
