Specifications:
System Integration Audio Processor: The inherent sound quality inside a vehicle varies widely. Numerous factors; including media used, vehicle type, speakers, etc. contribute to this inconsistency. The Alpine PXA-H800 System Integration Audio Processor is able to compensate for many of these factors to optimize the sound automatically. The processor allows you to upgrade your vehicle's factory or aftermarket sound, in conjunction with an aftermarket amplifier, while leaving all of your factory or aftermarket equipment and controls intact. The Alpine PXA-H800 lets you keep the look and functionality of your vehicle's factory radio or your aftermarket head unit; including steering wheel controls, Bluetooth wireless technology, DVD video capability, navigation, iPod support, SiriusXM Satellite Radio, Auxiliary inputs, and more. The PXA-H800 also maintains control over the sound using your vehicle's factory or aftermarket radio volume control. The PXA-H800 provides all the audio processing functions necessary to enable your factory or aftermarket system to reach the highest levels of sound quality.
Audiophile-Grade Components: A series of ultra-high performance audio components have been built into the PXA-H800 to achieve the heritage quality sound of Alpine.
ImprintEQ: ImprintEQ is a hardware/software combination that can overcome the acoustic problems present in every vehicle interior. ImprintEQ obtains the optimum acoustic effect from each seat position, based on the automatically measured acoustic data of vehicle's cabin. The software will optimize the sound stage, tonal balance, and definition automatically. You can measure up to 6 listening positions (All, Front, Front Left, Front Right, Rear). Once the automatic acoustic measurement is complete, the ImprintEQ will provide 4 target curves to choose from.
Time Correction: Digital Time Correction lets you achieve optimum sound staging by ensuring that the sounds from all speakers reach your ears at the same time. The time correction feature delays the audio signal to the speakers closer to the listener. This effectively creates a perception of increased distance for those speakers. Time Correction allows the listener to be placed at an equal distance from all speakers for optimum staging. Up to 8 channels can be automatically or manually corrected, from 0 to 20ms in 0.5ms steps.
RoadEQ: Even superior sound can be degraded by road, wind and air conditioner noise. RoadEQ takes the internal and external inputs and cancels out the noise to deliver optimal sound to your ears. It compares the original and recorded signals to create frequency-specific level adjustments to cancel the noise components. This powerful processor performs these operations at 48,000 times per second. The RoadEQ compensates for constantly changing noise, so always keep the included microphone connected. The mic should be installed on your sun-visor with the included clip.
MX (Media Xpander) Plus: MX (Media Xpander) Plus restores and enhances sound quality that is lost in the recording or transmission processes. This exclusive Alpine technology is especially good for making compressed digital audio files from iPod or other media players sound better. It is also effective for older recordings on CD, and improves the bass from factory-installed speakers. This helps to improve music clarity even in a cabin with loud road noise. There are various MX Plus settings to choose from based on your listening content.
Compressed 1-3: This corrects information lost in the compression process and reproduces a well-balanced sound close to the original. By supplementing mid- to high-frequency sound data, the sound is reproduced with more brightness and ambience.
Music 1-3: Lower register sounds (drums, bass, etc.) and vocals are emphasized for clean and clear output.
Cinema: Video dialog is reproduced more clearly, while action movies are reproduced with more powerful sound.
Action: Action movies are reproduced with more powerful sound.
Drama/Talk: The dialogue portion of a video is reproduced more clearly.
31-Band Graphic EQ: The Graphic EQ divides the audio band into 31 individual bands. Each band is individually controlled to balance the sound and enhance detail. The Graphic EQ provides 31 bands (20-20kHz; 1/3 octave steps) for each of the five speaker channels, plus 10 bands (20-160Hz; 1/3 octave steps) for the subwoofer channel; with gain from -12 to +12dB.
10-Band Parametric EQ: The Parametric EQ has fewer bands, but gives more control over where the band is located in the audio spectrum. You can also control how much overlap with adjacent frequencies (Q-factor). This provides you with a sound control feature of professional-level which allows you to adjust an extremely n arrow range in pin-point fashion without affecting the neighboring sound regions. You get 10 bands (20-20kHz; 1/6 octave steps) for each of the five speaker channels, plus five (20-200Hz; 1/6 octave steps) for the subwoofer channel; with detailed Q-settings (0.5/1.0/1.5/2.0/2.5/3.0/4.0/5.0) and gain from -12 to +12dB.
Digital Crossover: The PXA-H800 is equipped with a digital active crossover. The crossover limits the frequencies delivered to the outputs. Each channel is controlled independently. Thus, each speaker pair can be driven by the frequencies for which they have been optimally designed. The HPF (high pass filter) cuts the lower frequencies and allows the higher frequencies to pass. the LPF (low pass filter) cuts the higher frequencies and allows the lower frequencies to pass. The slope and level of each channel is also adjustable.
Phase Selector: You can adjust the phase (0° or 180°) of each speaker (Front High, Front Mid, Front Low, Rear, Center, Subwoofer).
Level Adjustment: You can independently adjust the level of each speaker channel (Front Left, Front Right, Center, Rear Left, Rear Right) from -10 to +10 dB. You can also adjust the PXA-H800's subwoofer output from 0 to 15dB in order to increase your system bass output without increasing the overall volume.
Rear Mix: This function mixes the front channel audio signal with the audio signal output from the rear speakers, improving the sound in the vehicle's rear seat. This is used in a system where there is no subwoofer and rear speakers can product lower frequency sounds than the front speakers. The Rear Mix can be set to -6, -3, 0, +3, or +6 dB.
Center Bass Split: Turning on this function sends the center channel low frequencies equally to the front left and right speakers. this enhances the overall sound when using a small center speaker. This is used when the center speaker has a small diameter and cannot produce low frequency sounds. You can set the Center Bass Split function to 200, 225, 250, 280, 315, 350, 400, 450, or 500Hz.
External Microphone: The included external microphone must be placed at ear level inside your vehicle during the automatic measurement process, (a camera tripod is useful for this purpose). The direction of the microphone will not affect the measurement. During the automatic measurement process, your vehicle should be parked in a quiet location with the doors, windows, and sunroof closed; turn off the engine, heater, and AC. The microphone is permanently installed on your vehicle's sun-visor for the RoadEQ function.
6ch Audio Inputs (Aux Input): With six low-level (RCA) inputs, you can connect six channels (Front, Rear, Center, Sub) of sound from an aftermarket head unit which features preamp outputs. You can also choose to connect additional audio source devices (based on menu settings). With six speaker-to-RCA adapters, you can also connect six channels of sound from almost any factory or aftermarket head unit that does not have preamp outputs. There's no need for separate line output converters. The PX-AH800's Aux Input offers several settings.
4V/8ch Audio Outputs: A 4V/8ch preamp signal feeds the audio from the PX-AH800 to your aftermarket amplifiers and speakers, allowing a substantial sound quality upgrade. The PXA-H800 has the ability to operate a full-range, 2-way, or 3-way front speaker output system configuration, with rear speakers and sub.
2 Digital Inputs: The Alpine PXA-H800 features two optical (toslink) digital inputs for connection of an external automobile-grade Blu-ray/DVD player.
2 Ai-NET Connections: The PXA-H800 is fitted with two Ai-NET ports for connection of an Alpine head unit or changer which also features an Ai-NET connector.
Optional Auxiliary Input: The KCA-121B (500KCA121B, sold separately) allows you to adapt the unit's Ai-NET port to a stereo RCA (Aux) input for connection of an additional non Ai-NET device.
