There's nothing like the cozy confines of a car to emphasize the thrilling dynamics of surround sound, and Alpine's PXA-H701 audio processor can help you experience the impact of multichannel sound in your vehicle.

The processor features three optical digital inputs, so you can connect each of your digital video sources with just one cable. The processor decodes the Dolby® Digital or DTS® signal from your DVDs and sends it to the external amplifiers that power your front, rear, and center-channel speakers, plus your subwoofer. The PXA-H701 even translates your stereo CDs into vivid multichannel sound.

If you're using the PXA-H701 with a compatible Alpine in-dash DVD player, you can use the player's touchscreen controls to adjust the system. If you're using the processor with an outboard DVD player or a non-Alpine in-dash player, you'll need an optional Alpine controller to make system adjustments.

No center-channel speaker in your car? The processor can create a "phantom" center for you, so you hear the dialog in the middle, where the center channel normally would be. The processor also includes digital time correction, graphic and parametric equalizers, frequency filters, and MediaXpander — sonic enhancement features that help you get your movies and music sounding just right in your vehicle.

Alpine PXA-H701

Crutchfield Customer Review (What's this?)

I have been using this product with both the Alpine IVA-W200 which integrates awesome and allows for an amazing amount of customization in terms of setting crossover points for individual speakers, along with time correction along with the parametric EQ. There is no need for a center channel with the phantom center channel feature it is the best car audio listening experience ever. This product integrates perfectly with the alpine multimedia units and I also have used it with the CDA- 9887 with its own control unit, the experience is very different because the H 701 gives you more adjustability in terms of sound correction but the display leaves something to be determined. Its super easy to integrate but I should warn that to use this to its full potential you must have a mid to high level of car audio experience because it will not program itself. I would say this as a must for anyone installing 5.1 in their vehicle, I have tried the other brands such as Audio Control and alpine takes the prize hands down. The one down side is that the wiring harness for the unit is not very long so its hard to find a place to hide the thing because it is not that small and depending on the vehicle you may not be able to fit it under the seat.



AWESOME with W205!!!!!!!!

Crutchfield Customer Review (What's this?)

I bought the PXA-H701 for my IVA-W205 and it is absolutely awesome when fine-tuned. You do not need a center speaker. The phantom center speaker function works great with movies and surround sound. The apple lossless from my iPod sounds perfect without the media expander function. I played around with the crossover and slope adjustments until it sounds perfect. You can also add bass to any of the speakers to fine tune the sound further. Time correction adds the final touch.



Excellent when paired with a nice Alpine head unit

Peter from San Ramon, CA on 5/15/2006

Crutchfield Customer Review (What's this?)

I have an Alpine IVA-W200 to control this and it is staggering how much you can do with it. This isn't for everyone, but if you want true 5.1 (most decks that play DVDs downmix to 2 channel), or if you want TOTAL control over your crossover points, slopes, parametric EQ, time correction, etc., then this is definitely worth it. Make sure you get a center channel if you use this.<BR><BR><BR>My only gripe is that you can't do automatic time correction through the head unit (you need the seperate controller for that).

Product Overview: The Alpine PXA-H701 Multimedia Manager allows you to add multi-channel music and movie soundtracks with digital sound processing to virtually any system. It can be controlled by the IVA-D310, DVA-9965, and DVA-9860 head units, or used as a stand-alone system with the RUX-C701 controller (sold separately). The PXA-H701 offers Dolby Digital and DTS decoding, and allows you to connect up to three source components via optical digital inputs. In addition, you can make multiple audio adjustments using the built-in graphic and parametric equalizers and digital time alignment.

Digital-to-Analog Converters: The unit is equipped with eight 26kHz/24dB MDACs (multi-level digital-to-analog converters).

Digital Time Alignment: You can perform digital time alignment to correct the time errors caused by the major differences in the distances between the vehicle's speakers and a particular listening position. Time correction can be adjusted manually by measuring the distances to each speaker and applying time correction values to each speaker. Audible time correction can be made from 0.05 ms to 20.00 ms in 0.05ms steps. You can also perform time correction automatically when the optional RUX-C701 control unit and the microphone included with the controller are used.

Graphic Equalizer: The built-in graphic equalizer allows you to modify the sound to suit your taste using 31 bands each for the front (left and right), rear (left and right), and center speakers. Adjustable frequencies are 20Hz to 20kHz in 1/3 octave steps. An additional 10 bands are available for the subwoofer from 20Hz to 160Hz in 1/3 octave steps. Levels are adjustable +/- 9dB in steps of 1dB.

Parametric Equalizer: For correcting undesired peaks and dips at specific frequencies not affected by the graphic equalizer's fixed frequency bands, you can use the built-in 11-band parametric equalizer and tune to those frequencies. Five frequency bands can be adjusted for the front (left and right), rear (left and right), center, and two bands for the subwoofer. Levels can be adjusted +/- 9dB in steps of 1dB, and the band width (Q) can be adjusted in 6 steps of 0.5, 1, 2, 3, 4 or 5. Selectable frequencies include:

  • Front, Rear, and Center:
    • Band 1: 20Hz to 500Hz (29 steps)
    • Band 2: 50Hz to 1.2kHz (29 steps)
    • Band 3: 125Hz to 3.2kHz (29 steps)
    • Band 4: 315Hz to 8kHz (29 steps)
    • Band 5: 800Hz to 20kHz (29 steps)
  • Subwoofer:
    • Band 1: 20Hz to 80Hz (13 steps)
    • Band 2: 50Hz to 200Hz (13 steps)

Active Crossover: The PXA-H701 is equipped with an active crossover, allowing the frequency bands to be split before amplification. You can activate two low pass and high pass filters for the front, and one each for the rear, center, and subwoofer. The front and rear crossovers can have different adjustment values for the left and right channels, if desired. All crossovers have a selectable slope of 6, 12, 18, 24, or 30dB/octave, or can be turned off independently. Crossover frequencies include:

  • Front 1: (select Tweeter or Full Range)
    • Tweeter:
      • High Pass: 1kHz to 18kHz (cannot be set to "Off")
      • Low Pass: 1.1kHz to 20kHz
    • Full Range:
      • High Pass: 20Hz to 18kHz
      • Low Pass: 22Hz to 20kHz
  • Front 2:
    • High Pass: 20Hz to 18kHz
    • Low Pass: 22Hz to 20kHz
  • Rear:
    • High Pass: 20Hz to 18kHz
    • Low Pass: 22Hz to 20kHz
  • Center:
    • High Pass: 20Hz to 18kHz
    • Low Pass: 22Hz to 20kHz
  • Subwoofer:
    • High Pass: 20Hz to 180Hz
    • Low Pass: 22Hz to 200Hz (cannot be set to "Off")

Media Xpander (MX): The Media Xpander makes vocals or instruments sound distinct regardless of the music source. You can set an MX effect level for each connected source.

Bass Compensation: Bass Comp can be activated to accentuate bass frequencies. You can choose any of three levels of Bass Comp to suit your tastes.

Surround Features

Dolby Digital/DTS: The PXA-H701 can decode 5.1-channel Dolby Digital and DTS signals from a connected DVD player and output these discrete signals to the appropriate output jacks for front left, front right, rear left, rear right, center, and subwoofer preamp outputs.

Dolby Pro Logic II: You can apply Dolby Pro Logic II processing on any 2-channel music or movie signal from a CD, DVD, FM or Satellite Radio. You can select Dolby Pro Logic II Music to enhance stereo music recordings, or Dolby Pro Logic II Movie to simulate 5.1 channel surround sound. In addition, you can choose a Rear Fill function for 2-channel Dolby Digital and DTS signals and output the front channel signals to the rear speakers.

Speaker Setup: The PXA-H701 lets you adjust the output according to the playable frequency range of your speakers. You can designate the size of each set of speakers as "small" or "large" based on their ability to play sounds at 80Hz or lower, and set the subwoofer for "on" or "off". The level for each speaker (front left and right, rear left and right, and center) can be set in a range of +/-10dB, either manually or automatically.

Phantom Center: If you do not have a designated center channel speaker, the unit can distribute the center channel audio information to the front left and right channels. This creates a simulated or "phantom" center speaker directly in front of each listener. The level of this acoustic center image can be adjusted within a range of -5 to +5, allowing you to shift the image from one side to the other.

Standard/Maximum Sound: Dolby Digital are compressed to achieve powerful sound at regular volume levels. This compression can be canceled so you can achieve an even more powerful sound at high volume levels. You can choose Standard or Maximum listening modes to suit the level you desire.

DVD Levels: You can independently set the output levels for DVDs for Dolby Digital, DTS, Dolby Pro Logic II, and PCM.
