Alpine PXE-H660 Owners Manual - Page 5

Features/Description The Alpine PXE-H660 is a versatile processor that takes an OK sounding factory system turns it into a high-end, audiophile system. The PXE-H660 utilizes advanced sound tuning of the factory equipment to correct the acoustical problems inherent in any vehicle. It's equipped with Alpine's Imprint technology. Using AntEQ™ to remove any factory preequalization, Audyssey MultEQ® flattens the frequency reponse inside the vehicle's interior and adjusts the overall reponse to a pre-selected target curve. Once sound levels are balanced, and the system is tuned for optimum response, the addition of Alpine amplifiers and speakers give significant improvement over your factory hardware. Additional amps for tweeters and subwoofers provide a quality, bi-amped system extending the system's response far beyond what a normal factory system is capable of. It's easy to upgrade from factory to Alpine! The automotive cabin is a minefield of audio disruptions. The car's cabin is made from materials that reflect and absorb sound. This causes peaks and clips in music reproduction. For instance, windows reflect and amplify high frequencies. Leather covered surfaces like the seats and dash also reflect and change certain frequencies. Also, carpeted areas in the cabin absorb and suppress mid frequencies. It is dangerous and illegal for the driver to watch TV/Video while driving ! WARNING any vehicle. The driver may be distracted from looking ahead and an ac- cident could occur. 5
