Clock Display Note
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.
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
- 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.
- 4-band Digital Parametric
EQ: The 4-band parametric EQ lets you select a center frequency, then
adjust its output level and even the "width" of the boost or cut
for precise system tuning. The parametric EQ offers a selection of 4
frequencies and 15 center frequencies: Band 1 (40Hz, 60Hz, or 90Hz), Band 2
(100Hz, 150Hz, or 200Hz), Band 3 (500Hz, 700Hz, 1kHz, 2kHz, 4kHz, or 6kHz),
and Band 4 (10kHz, 12.5kHz, or 15kHz). Once a frequency is selected, you can
adjust its level from -12dB to +12dB in 1dB increments. The Q for each band
can be adjusted independently: Band 1 (1, 2, or 3), Band 2 (1, 1.5, or 2),
Band 3 (1, 2, or 3), and Band 4 (fixed bandwidth). In
addition to the user-adjustable EQ (Users 1 or Users 2), tone presets are
stored into memory, allowing you to recall the
best setting for different types of music. You
may choose from the following tone presets: Rock, Pops, Jazz & Blues,
Electrical, Hip Hop & Rap, Easy Listen, Country, Classical, News, or
- 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.
- 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.
The CDA-9830 features the MediaXpander function, which is offered on Bass Engine
Pro, Bass Engine Plus, and some Bass Engine models. 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 only one or two expansion modes available for external
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 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
Disc and Station Titling: Titles
of up to 8 characters in length may be entered for up to 24 radio stations and
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.
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.
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.
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.
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.
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
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.
