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.
Note: The addition of an external aftermarket
amplifier (sold separately) is required. The Alpine RUX-C800 wired remote
sold separately) is also required, unless using an "Imprint"-compatible
Alpine head unit. In addition, you will need a Windows PC.
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.
- A complete 6ch analog-to-digital converter, the CIRRUS CS5366, is ideal
for audiophile sound quality. The ADC uses a differential input
architecture, which provides excellent noise rejection.
- To reproduce the sound source without degradation, two ultra-fast
accurate 32-Bit floating-point SHARC DSP's are used for high-performance and
rich audio feature applications.
- The use of four Wolfson 24-Bit D/A converters (normally a component
found only in professional recording systems) help to ensure superb detail
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.
- Reference: Enjoy the rhythm and balance
of music to the best acoustic effect, suitable for the vehicle
- Reference w/ Mid-Range Comp: Select this if
the tweeter and midrange speaker are installed in the dashboard,
and mid or high frequency range harshness is apparent.
- Linear: A linear (flat) acoustic effect is
actualized. This setting recreates the balanced sound of a studio
- User: Allows you to adjust the target curve
manual from -6 to +6 dB.
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
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
Graphic and Parametric EQ: The PXA-H800 provides either graphic
or parametric equalization.
- 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.
Cutoff Frequency Adjustment Range||Slope||Level|
Front High||20Hz to 18kHz ||22Hz to 20kHz||0 (Off),
-6, -12, -8, -24, -30, -36 dB/octave||-24 to 0
dB (in 0.5 dB steps)|
|1kHz to 18kHz (tweeter only)||1.1kHz to 20kHz (tweeter only)|
|Front Mid||20Hz to 18kHz ||22Hz to 20kHz|
|Front Low||20Hz to 18kHz ||22Hz to 20kHz|
|Rear||20Hz to 18kHz ||22Hz to 20kHz|
|Center||20Hz to 18kHz ||22Hz to 20kHz|
|Subwoofer||20Hz to 180Hz||22Hz to 200Hz|
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
Surround Sound: The Alpine PXA-H800 System Integration Audio
Processor supports up to 5.1-channel surround sound from multi-channel and 2-channel
- Dolby Digital/DTS: Enjoy true 5.1-channel
surround sound just like your home cinema system. You can hear
multi-channel sound from movie and music sources in the Dolby
Digital and DTS Digital Surround formats. With Dolby Digital,
the dynamic range is compressed so that powerful sound can be
achieved at regular volume levels. This compression can be
cancelled to achieve an energetic sound with even great power,
like the sound in a movie theater. This can be set to Standard
- Dolby Pro Logic II: The PXA-H800 also provides
Dolby Pro Logic II decoding, so you can even enjoy stereo recordings
in surround sound. You can choose between a Music or Movie mode. Music
mode allows you to adjust the center width which provides the optimum
vocal localization by adjusting the center channel position in between
the center speaker and the L/R speakers.
- Euphony: Euphony makes it possible to enjoy
5.1-channel sound from 2-channel sources. It creates natural surround
sound from CD or iPod with wider soundscapes and harmonics. It especially
enhances vocal and instrumental quality, for a superior sound field and
no listener fatigue.
Note: Even if you don't have a center
speaker, you can still enjoy 5.1-channel sound. Alpine has included
a Bi-Phantom function, which uses the front left and right channels
to create a phantom center channel, enhancing vocal quality.
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.

(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.
Sound Manager Software: Use the supplied Software Installation
Disc (ver.1.1) to install the Sound Manager Software onto your Windows laptop. This software is compatible with Windows XP, Vista, and 7 (32-bit editions
only). Once you have downloaded the Sound Manager Software onto your
laptop, you can then connect the PXA-H800 to your laptop with the supplied USB
cable in your vehicle. An easy-to-use GUI will appear on your computer's monitor
that guides you through the automatic measurement process and lets you make detailed
audio settings. You can store six different tuning presets on your laptop for later
selection or for use to tune different vehicles.
Remote Control: The Alpine RUX-C800 wired remote controller
sold separately) must be used to setup and control the Alpine PXA-H800
System Integration Audio Processor, unless you have an "Imprint"-compatible
Alpine head unit. The Alpine RUX-C800 provides a convenient way to
adjust the PXA-H800's settings from your vehicle's driver seat. The remote provides
full command of the PXA-H800's settings & functions. The RUX-C800 is equipped
with a 3-way rotary knob and six push-button controls that let you adjust the Alpine
PXA-H800's settings, as well as switch sources, adjust volume, and mute playback. The
Alpine RUX-C800 in-dash controller features a BioLite display that provides detailed
information regarding audio functions and settings. The BioLite display takes advantage
of biochemical luminescence technology to deliver maximum visibility in daylight and
provides a wide viewing angle. You can adjust the unit's button illumination between
blue and red to match your vehicle's interior lighting. The RUX-C800 comes with a
flush-mount bracket to custom install the remote controller in your vehicle's dash.
The RUX-C800 also comes with two-side tape to simply adhere the wired remote controller
to your dash.
