I got really into it around age 12, when I got hold of a Pentax K 35mm camera. My father is a photo nut also, and we had access to a darkroom.
Ever since then I have delighted in trying out new cameras, lenses, and photo techniques. Working here at Crutchfield, I get to handle all the new and cool camera gear I can get my hands on. I'm also into audio, from car audio to home audio to headphones. I'm a music lover, and an eye-opening moment for me was discovering just how much more there is to musical recordings when you listen using high-quality gear. It's an experience I try to pass along to others as often as possible.
I truly believe that having good quality gear in your car or home can really enrich your life. I started getting into the video side of things early on in my Crutchfield career while I was a copywriter for car audio products. In those days our video program was just getting started, and many of us pitched in when our writing and editing duties allowed. Today, we have a dedicated team that makes hundreds of videos a year, including spotlights on products and product lines, how-to videos, videos that shine a light on our company, end everything in between.
I am proud to be a part of that team and of the work we do. My job is a lot of fun because I get to play around with all the cool stuff you see on our website while I'm making videos. Getting hands-on with the gear helps me see what I should show you about a product, and I look at our videos as a way of having a conversation with you when you are considering a purchase. If I do my job well, you should come away from a Crutchfield video understanding why you do — or don't — want that product.
In the end, it's gotta be something you enjoy. Makes any system sound spectacular — even a factory system Frustrated by the way your car audio system sounds? You're not alone. Even so-called "premium" factory systems often have serious limitations in the sound department.
Alpine built the PXA-H digital sound processor for one purpose: to deliver pristine sound to aftermarket amps, speakers, and subs. It takes control over your sound before you send it to an amplifier, stripping away hard-coded factory settings and starting from scratch. You'll even find speaker-level inputs, which lets you hook up your factory stereo or another source that lacks preamp outputs.
If you can't replace your factory radio In many newer cars, the factory radio also controls critical functions like climate controls and safety systems. That makes for a convenient interface, but it can make it difficult or impossible to install a superior aftermarket receiver. But if you still crave pristine sound, you can keep your factory look and feel — and let the Alpine PXA-H handle the sound processing.
This processor works with aftermarket stereos, too. All systems have some sort of DAC, but the Wolfsons found in the PXA-H are normally only found in professional recording equipment — the same sort of equipment your favorite artist probably used to record your favorite song.
Advanced digital processing puts you front and center The driver's seat has a built-in disadvantage in any audio system: it's not in the center. You have at least four, and more likely six or more speakers in your car. But you're sitting right next to one or two of them, so your music might sound like it's pulling to the left. The PXA-H adjusts the timing of all the speakers in the car so their sound arrives at your ears at the same time, effectively moving the soundstage to the center where it belongs.
It's like sitting in the front row center at a concert. Digital magic helps overcome car audio limitations Alpine knows that a moving car creates somes challenges in the sound department, such as road noise and differing speaker configurations.
To compensate for these and other situations, they've built some clever functionality into the PXA-H, such as:. You can also change sources and view detailed info about your system. It looks a bit like an in-dash receiver and comes with an installation kit.
Hone your sound to razor-sharp perfection Alpine gives you a bevy of ways to get exactly the sound you want. The easiest way is ImprintEQ, which uses an included microphone to optimize the signal for the acoustics in your car, then allows you to tweak the settings manually if you wish. If you'd rather take control from the start, you'll find some serious equalizers: 31 bands for each of the five channels, plus 10 bands for the subwoofer.
You'll also find a band parametric EQ for each of the five channels, plus a 5-band parametric EQ for the subwoofer. Connect the PXA-H to your laptop to get a nice graphical depiction of your audio settings, plus the ability to store different settings for later recall — handy if you plan to move the processor to another vehicle now and then.
Variety of connections Connections include front, rear, center, and sub channels with both speaker-level and RCA inputs, plus two digital optical inputs. There are also two Ai-NET connections for hooking up Alpine gear, along with 8-channel preamp outputs for feeding a 4-volt signal to aftermarket amplifiers. The preamp outputs are configurable to accommodate a variety of audio setups, from bi-amped front speakers, to full surround sound.
The RUX-C wired remote controller sold separately is also required, unless using an "Imprint"-compatible Alpine receiver. In addition, you'll need a Windows PC. Alpine PXA-H owner's manual.

System Integration Audio Processor: The inherent sound quality inside a vehicle varies widely.
Numerous factors; including media used, vehicle type, speakers, etc. 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-H 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-H also maintains control over the sound using your vehicle's factory or aftermarket radio volume control. The PXA-H 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-H to achieve the heritage quality sound of Alpine. 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. 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.
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, 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. 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. 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 slope and level of each channel is also adjustable.
