Alpine PXE-C80-88 - 8-channel DSP amplifier

With the introduction of the Alpine OPTIM8 , we have eliminated many of the problems and confusion that normally accompany trying to tune the sound of your system yourself using a digital signal processor or DSP/amplifier. For this reason, the PXE-C80-88 8-channel DSP amplifier features automatic sound tuning and high-performance power, so you can experience the exceptional fidelity, clarity, balance and liveliness of your music without having to spend hours fiddling with controls and test equipment.
Matrix mixing allows you to summate and control input and output signals. Fully adjustable high-pass, low-pass and band-pass filters, as well as 31-band equalizers on each channel, tailor the sound to your speakers and smooth out peaks or dips in the frequency response caused by your vehicle's interior. With the time correction you can center the stereo image for your listening position. After the initial setup with your PC , all settings of the PXE-C80-88 can be made automatically using the app and the integrated microphone on your iPhone or a separate measurement microphone such as the Alpine KTX-CSP1 on the PC. PC users can make all sound settings manually to create a customized soundscape.
The PXE-C80-88 can of course be used as a standalone processor for use with your own amplifiers. However, with the integrated 8-channel amplifier it has enough power for your complete system. There are six channels available, each with 35 watts RMS on speakers with 4 ohm impedance or 70 watts RMS on speakers with 2 ohm impedance. This makes it equally suitable for factory and aftermarket speakers . In addition, the remaining two channels, each with 130 watts RMS on 4 ohms or 260 watts RMS on 2 ohms, can be used for powerful bass-midrange speakers and subwoofers.

Alpine OPTIM8: The new way to optimize car audio

The groundbreaking Alpine OPTIM8 is the new way to provide an all-in-one solution for effortlessly optimizing and amplifying any sound system with remarkable precision. The powerful DSP amplifier features Eilex PRISM™ technology, which offers a new way to perfect car audio. It measures the frequency response using the APVD (Acoustic Power Volume Density) method and simultaneously corrects timing and phase errors in speaker systems. This technology ensures that the sound reproduction is as close to the original as possible. In return, it offers remarkable musicality and intelligibility. This optimization happens automatically and usually takes no longer than 5 minutes.
