Alpine designed the PXE-H660 System Integration Audio Processor for people who want to create a full car audio system by adding amps and subs, but who don't want to replace the factory stereo. The processor cleans up the output of your factory radio, then applies special IMPRINT sound-shaping technology that tunes your amp and speaker setup to your vehicle. You'll build a great-sounding system, while keeping the look and functionality of your factory radio's dashboard setup, steering wheel controls, and factory extras.
Cleans up your sound
A 512-band equalizer removes the preset EQ curve from your factory radio's output, sending a clean, unequalized signal to your amplifiers through the processor's four sets of preamp outputs. High- and low-pass filters on each output route the right frequencies to each amp, while the 4-volt signal keeps extraneous noise out of your system.
IMPRINT sound tuning technology
The PXE-H660 takes the guesswork out of system setup with its impressive automatic sound tuning feature. Connect the included microphone and place it in your preferred listening position in the vehicle. IMPRINT will analyze the acoustics in each listening position, adjusting the sound so that any seat in the car can be the best seat in the house. You can use either the PXE-H660's controls or a PC loaded with the supplied software for easy system setup and adjustment.
Like to tweak it yourself? No problem — you'll find a built-in 3-band parametric equalizer, manual crossover controls, and manual time-correction controls built in as well. You'll retain the use of your factory stereo's volume knob for on-the-fly adjustments.
