The PXA-H800 provides all the audio processing functions necessary to enable the system to reach the highest levels of sound quality.
A few years ago, Alpine released the AlpineF#1Status series of ultra-high performance audio components. Many of the lessons learned from developing those models, about high-grade parts and how to apply them, are now being put to good use in products like the PXA-H800. One example is the use of four Wolfson 24-Bit D/A converters, which are generally found only in professional recording systems and help to ensure superb detail and soundscape. Another is the use of two 32-Bit floating-point SHARC DSPs, which precisely reproduce the sound source with no degradation. Other top quality parts are a 6-layer PCB and a 24-Bit A/D converter for high quality RCA input and 114dB dynamic range at the device level.
Digital Time Correction lets you achieve optimum sound staging by ensuring that the sounds from all speakers reach your ears at the same time. Up to 8 channels can be corrected automatically or manually, from 0 to 20ms in 5ms steps. Digital high pass and low pass filters allow you to set slopes from 0 to –36 dB/oct., with gain from –24 to 0dB. You can customise your system with the exact frequency crossovers you want.
ImprintEQ is a hardware/software combination that can completely overcome the acoustical problems present in every vehicle interior. It optimises the sound stage, tonal balance and definition automatically, in just a few minutes. After the tuning is complete, you can manually tweak the settings if you desire.
The PXA-H800 provides both graphic and parametric equalisation. The graphic EQ provides 31 bands for each of the five channels, plus 10 bands for the subwoofer, with gain from –12 to +12dB. The parametric EQ lets you select a band and then adjust the output level and width for precise tuning. You get 10 bands for each of the five channels, plus 5 for the subwoofer, with detailed Q settings and gain from –12 to +12dB.
With the PXA-H800, you can enjoy a true 5.1-channel surround sound experience just like you get from your home cinema system.
You can hear multi-channel sound from movie and music sources in the Dolby Digital and DTS Digital Surround formats. The unit also provides Dolby Pro Logic II decoding, so you can even enjoy stereo recordings in surround sound.
Even if you don’t have a centre 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 centre channel, enhancing vocal quality.
To make best use of your PXA-H800, it is strongly suggested to use RUX-C800 (sold separately). The RUX-C800 provides you a full command of all PXA-H800 functions and a display with detailed information.
Demonstrating its unmatched commitment to mobile sonic excellence, Alpine packed even more technologies into the PXA-H800, including the ability to fully tune the sound on a PC.
Connect your PC to the PXAH800 with a USB cable and you can get a cool-looking, easy to use GUI that lets you make detailed audio settings. You can also store numerous settings on the computer, for later selection or even for various different vehicles.
This exclusive Alpine technology restores sound quality that is lost in the recording or transmission processes. No adjustments are necessary, you just push a button. MediaXpander+ is especially good for making compressed digital audio on iPod or other players sound better, but it is also effective for old recordings on CD, and also improves the bass from factory-installed speakers.
Even superior sound can be degraded by problems like road noise, wind noise and air conditioner noise. RoadEQ uses a microphone to record the music plus noise inside the vehicle. It compares the original and recorded signals, then creates frequency-specific level adjustments to cancel the noise components. A powerful processor performs these operations at 48,000 times per second.
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.
For those who want to retain their factory head unit, the PXA-H800 is a great way to upgrade the system with more sources and better sound quality.
With six speaker-level inputs, you can connect six channels of sound from a head unit and other components that do not have preamp outputs. There’s no need for separate line output converters.
With two Ai-NET connections, two optical digital inputs and six-channel RCA inputs, you’ll have no problem adding components for front and rear seat entertainment. And of course, with the PXA-H800 in your system, you’re assured of much higher sound quality than any factory system can provide.
The PXA-H800 turns any factory head unit into a sophisticated ImprintEQ audio system, with sound that is perfectly clear and precisely balanced for the best possible tonal response and imaging in your vehicle. If you’re serious about upgrading your system, start with the PXA-H800.
