You love music and you know good sound when you hear it. When you play your music on an audio system, you expect to be able to hear it with all the power, clarity and subtle expressive nuances of the original. Unfortunately, nothing dashes those expectations more thoroughly than the sonic environment of the car. The car interior is full of materials that actively distort and degrade the sound. Windows amplify and reflect high frequencies.

Shop all Alpine Signal Processors. Please confirm that this adapter will work with the stereo you intend to use. Find products that fit. My name is Ken. I seek the Holy Grail of car audio excellence. My favorite color is blue. I came to Crutchfield in During my six years as a Crutchfield Advisor, I learned a lot about the technology behind great car and home audio. I learned even more about what people wanted in their car stereo systems. I've been a writer for car audio and fitness tech at Crutchfield since Over the last few years, I've also carved out a niche producing demo videos for our in-dash car stereos.
The hands-on experience I get with car stereos while doing video production is an invaluable aid to me in learning about their exciting features. This helps me convey that information to our customers when I write about the stereo on our website. Before coming to Crutchfield, I spent 10 years teaching music in Charlottesville area schools. I keep my musical interests satisfied by volunteering as a classical music DJ at a local community radio station, and I stay up to date with the latest in outdoor tech by cycling, running, and backpacking.
Fun facts: I've completed an Ironman triathlon, run the Boston Marathon, hiked miles of the Appalachian Trail, and lost on Jeopardy! Many cars have acoustic problems that interfere with an in-dash receiver's ability to produce clear, well-balanced sound. Your receiver's equalizer may help, but Alpine offers a better way. Automatic adjustment The PXA-H analyzes over soundwave points to produce a perfectly corrected sound curve for your vehicle and then saves it safely in its memory.
The entire tuning process only takes about 10 minutes. Sonic toolbox If you want to get hands-on, the PXA-H also features a 5-band parametric or 7-band graphic equalizer, manual crossover controls, and manual 6-channel time-correction controls as well. It also adds three sets of 4-volt preamp outputs plus Alpine's sound-correcting MediaXpander function to your receiver.

The Imprint box and tuning kit include the hardware, software, and microphone necessary to measure multiple positions in the car and capture frequency and time domain information from the vehicle's actual acoustical environment.
Once the car's speaker location delays are measured, along with the frequency peaks and dips caused by the absorptive and reflective materials in the interior, MultEQ creates a set of equalization filters to correct the frequency response and time domain problems for each speaker in the vehicle.
It also removes sound distortion caused by the specific acoustical problems in the vehicle by applying unique FIR filters, using more than points along the frequency spectrum per channel. This optimizes the sound reproduction to the specific vehicle listening environment with much greater precision than can be achieved using typical graphic or parametric equalization. The result is a more accurate soundstage and smoother, more natural sound optimized to match your vehicle.
Equalizer: 10 typical equalizer settings are preset at the factory for a variety of musical source material. The head unit will also save six custom EQ curves you create by adjusting the units built-in EQ. Choose the parametric or graphic EQ:. Crossover: The active crossover can be used as a 2. A crossover limits the frequencies delivered to a given speaker, so you send only the frequencies for which the speaker is well suited.
The crossover adjusts the high pass filter or low pass filter of each band along with the slope and output level. You can adjust the following crossover settings:. Time Correction: 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. You can adjust the distance of each speaker and subwoofer 6-channel to the listener from 0 to Media Xpander: The MX Media Xpander 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 settings and each source can have its own setting. SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision. It includes a pair of studio-quality headphones, a combination DAC digital-to-analog converter and headphone amp, USB mobile adapters, and a guide to getting the most out of your session.
