About the Alpine PXA-H100 IMPRINT Audio Processor
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. The PXA-H100 IMPRINT Audio Processor plugs into the Ai-NET input on most 2008 Alpine receivers, analyzes your vehicle's acoustics, and uses the MultEQ feature developed by Audyssey Labs to adjust the receiver's output for the best possible audio performance.
Easy to use
In order to use the IMPRINT, you'll need to purchase Alpine's KTX-H100 tuning kit. Connect the microphone from the KTX-H100 tuning kit, then load the supplied software onto your laptop PC. Use the the included USB cable to connect your PC to the PXA-H100, then use the software to tailor your sound.
The PXA-H100 analyzes over 500 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. You can use the PXA-H100 with your Alpine's built-in amplifier or with external amps in your system.
If you want to get hands-on, the PXA-H100 also features a 5-band parametric or 7-band graphic equalizer, manual crossover controls, and manual 6-channel time-correction controls as well. The PXA-H100 provides a pass-through connection, so you can still add other gear to the Ai-NET bus. It also adds three sets of 4-volt preamp outputs plus Alpine's sound-correcting MediaXpander function to your receiver.

More details on the Alpine PXA-H100 IMPRINT Audio Processor
Imprint: By adding this PXA-H100 Imprint box and the KTX-H100 tuning kit (item number 500KTXH100) to a compatible Alpine head unit (with Ai-NET), a car's inherent acoustic shortcomings can be overcome with the MultEQ feature. Imprint also gives you much more sound adjustment flexibility as detailed below.
MultEQ: MultEQ, developed by Audyssey Labs, automatically optimizes the audio for the listening environment inside your vehicle. 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 500 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. You can select from - Flat, Pops, Rock, News, Jazz & Blues, Electrical Dance, Hip Hop & Rap, Easy Listening, Country, and Classical. 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:
- 5- Band Parametric EQ: The built-in Parametric EQ
allows you to adjust the following 5 frequency bands in 1/3 octave steps
from -6 to +6 dB at a bandwidth Q factor of 1, 1.5, or 3
- Band 1: 20 Hz to 80 Hz
- Band 2: 50 Hz to 200 Hz
- Band 3: 125 Hz to 3.2 kHz
- Band 4: 315 Hz to 8 kHz
- Band 5: 800 Hz to 20 kHz
- 7-Band Graphic EQ: The built-in Graphic EQ allows you
to adjust the following 7 frequencies from -6 to +6 dB
- Band 1: 63 Hz
- Band 2: 150 Hz
- Band 3: 400 Hz
- Band 4: 1 kHz
- Band 5: 2.5 kHz
- Band 6: 6.3 kHz
- Band 7: 17.5 kHz
Crossover: The active crossover can be used as a 2.2 channel (3-way; low-pass subwoofer, band-pass midrange, high-pass tweeter) or a 4.2 channel (2-way; high-pass front and rear, low-pass subwoofer). 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:
- 4.2 Channel:
- High Pass Filter: the front and rear outputs are individually adjustable; crossover from 20 to 200 Hz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB
- Low Pass Filter: the subwoofer output can be stereo or mono; crossover from 20 to 200 Hz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB
- 2.2 Channel:
- Tweeter/High Pass Filter: crossover from 1 kHz to 20 kHz in 1/3 octave steps with a slope of 6, 12, 18, or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB
- Midrange/Band Pass Filter: a band pass has both high pass and low pass filters; HPF 20 to 200 Hz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct; LPF from 20 Hz to 20 kHz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB
- Subwoofer/Low Pass Filter: the subwoofer output can be stereo or mono; crossover from 20 to 200 Hz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB
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 132.7 inches.
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.
