AntEQ is a process that removes the distortion and coloration caused by the factory head unit's built-in equalizer. AntEQ creates a flat and clean input signal for the PXE-H660 or PXE-H650, which then can be processed by MultEQ.
MultEQ is a process that measures the acoustic characteristics of your vehicle using a setup disc and an included microphone. MultEQ then applies a 512-band equalizer and time correction to each speaker channel, creating a balanced and natural sound that matches your vehicle's acoustics and your listening preferences.
The result of IMPRINT sound technology is a customized sound that lets you experience music the way the artist intended, free from distortion and coloration.
What are the Differences Between PXE-H660 and PXE-H650?
The PXE-H660 and PXE-H650 are both system integration audio processors that use IMPRINT sound technology, but they have some differences in features and specifications.
Feature

No
The main difference between the PXE-H660 and PXE-H650 is that the PXE-H660 has an additional preamp output channel for front 2 speakers, which can be used for bi-amping or active crossover systems. The PXE-H660 also allows you to retain the use of your factory stereo's volume knob, while the PXE-H650 requires you to use an external volume controller (sold separately).
How to Install and Set Up the PXE-H660 or PXE-H650?
The installation and setup of the PXE-H660 or PXE-H650 are similar, except for some minor differences in wiring and configuration. Here are the basic steps:
Install the processor unit. The processor unit can be mounted under a seat, in the trunk, or behind the dash. You will need to connect the power, ground, remote turn-on, speaker input, speaker output, preamp output, microphone input, and USB cables according to the instructions in the manual.
Connect the aftermarket amplifiers and speakers. You can use any combination of amplifiers and speakers that match your system's impedance and power ratings. You will need to connect the preamp outputs from the processor to the inputs of the amplifiers, and the speaker outputs from the amplifiers to the speakers.
Run the setup disc and microphone. You will need to insert the setup disc into your factory head unit and play the test tracks. You will also need to place the microphone in different positions in your vehicle, following the instructions on the screen. The processor will measure the sound from each speaker and adjust the EQ and time correction accordingly.
Enjoy your IMPRINT sound system. You can now listen to your music with improved clarity, balance, and definition. You can also fine-tune the sound using the manual EQ and crossover filters on the processor, or using a PC software (sold separately).
