OK here were go. This is the CDA- 9833 Alpine Head Unit. I really want the BEST (besides a 7 inch screen one that cost 3k) Alpine has to offer. Now the CDA-(835 is actually the best but the only thing that changes it the Screen display. But I would TRY to win a bid on one of these off of eBay.
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.
Display Dimming: 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 display's 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 display is dim at all times.
Display Type: You may choose from the following three display types:
Type 1: the indicator on the left changes in a fixed sequence
Type 2: the indicator on the left changes according to the Multicolor Illumination
Type 3: the indicator on the left changes according to the audio level
Variable Button Color: The button illumination can be adjusted to any of 512 colors. The following color presets are stored in memory: Blue, Green, Amber, and Red. In addition, you can store one custom color under the User's preset. The custom color can be selected by turning the rotary encoder and cycling though all 512 colors.
Display Font: You can customize the display by selecting one of two available display fonts.
V-Drive Hybrid Amplifier: A V-Drive MOSFET power unit is used to boost the incoming voltage from 14.4 volts (approximately) to 17.2 volts. The increased voltage allows the unit to deliver peak output of 60 watts x 4 channels. While providing high power output, this unit can draw a substantial amount of current, so the constant power wire must be connected directly to the positive terminal of the battery in your vehicle. For more info, please see the "Wiring Note" section below.
Bass Engine Pro: Bass Engine functions provide control over your system, so you can tailor the sound to your personal tastes. Bass Engine Pro includes the following functions:
6-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, rear left, subwoofer left, and subwoofer right speakers, all sounds reach your ears at the same time, providing optimized imaging and frequency response.
6-Position Digital Crossover with Adjustable Slope: The digital crossover allows you to choose from the following modes:
2-way Mode: A continuously variable 20-200Hz low-pass filter is available for the subwoofer outputs, and a continuously variable 20-200Hz high-pass filter is available for the front and rear preamp outputs. The slope for each filter can be set to 6, 12, 18, or 24dB/octave, or Flat. The level for each filter can be adjusted from 0 to -12dB.
3-way Mode: A continuously variable 20-200Hz low-pass filter is available for the subwoofer outputs, and a continuously variable 1-20kHz high-pass filter is available for the front preamp outputs. The rear preamp outputs have a continuously variable 20Hz-20kHz low-pass filter and a continuously variable 20-200Hz high-pass filter. The slope for each filter can be set to 6, 12, 18, or 24dB/octave, or Flat. The level for each filter can be adjusted from 0 to -12dB.
5-band Digital Parametric EQ: The 5-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. You can select a frequency for each of the following bands: Band 1 (20Hz, 25Hz, 31.5Hz, 40Hz, 50Hz, 63HZ, 80Hz, or 100Hz), Band 2 (250Hz, 315Hz, or 400Hz), Band 3 (1kHz or 1.2kHz), Band 4 (3.2kHz or 4kHz), and Band 5 (10kHz, 12kHz, 16kHz, or 20kHz). Once a frequency is selected, you can adjust its level from -6dB to +6dB in 1dB increments. The Q for each frequency can be set to 1, 1.5, or 3. In addition to the user-adjustable EQ (User's 1-6), 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, News, or Flat.
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.
MX (MediaXpander): The CDA-9833 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 sources.
i-Personalize: i-Personalize is an innovative way to customize select Alpine receivers to fit your specific listening needs. You log on to www.alpine-usa.com
and download user preferences (based on vehicle and system type) for time correction, crossover, and parametric EQ. After selecting your settings, you can burn them onto a CD-R, and upload them to the head unit. You can also upload the settings to the head unit using the optional Alpine HDA-5460 Hard Disk Drive player, if one is connected.
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.
