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.

interface with Apple iPods with a dock connector, fourth generation and newer.
